[jeffrey19621]

Could you please explain the benifits of this type of simulated runup ? I carefully lube (not to over extent ) . Just curious...

[JohnxWaynexGacy]

That valve train looks so much more stable then factory sbc stuff. Stamped steel rockers, and pushrods that could bounce around when the big heavy valves start floating. I bet this is a really good engine. Just out of curiosity, does the timing cover interchange with sbc?

[bluebomb49]

Amazing great stuff

[upcork1]

That music is horrible.Isn`t the whole point of a video of an engine running is to hear the engine.?

[captainkurk]

@upcork1 thank you

[captainkurk]

@upcork1 thank you.

[cougar1972xr7]

ford blue? why?

[mykidlets]

why are the valve springs tilted forward like that? im from autralia and our 253 is a v8 so that would be a nice cruisy six :)

[fiatnutz]

@mykidlets - The 235 uses the May Fireball combustion chamber, its a bit different than the trench or bathtub styles.

[AlabamaCrackerHonkey]

The F and 2F engines in older Landcruisers are based on this engine.

[upcork1]

I don`t understand why there is music with this video.Makes it seem really strange.

[mr48chevy1]

Ok, for all those arguing about explosion versus combustion. In a gasoline engine, the fuel/air mixture is ignited much like the gas is lit in a lighter. Combustion explosions in a gas engine are referred to as "pinging" and is very hard on the pistons.  Diesels, on the other hand, are controlled "explosions" as the fuel literally explodes in the cylinder. The difference is diesels are made to withstand it.

Very cool process, by the way.

[63echo]

i love this engine.im gonna put one in my Chevy LUV longbed

[mr1nutwonder]

why do you paint the inside of the engines, are they going to rust?

[stingraystud]

@mr1nutwonder some people paint the inside of an engine so the surface will be smoother than bare cast iron and the oil will run down to the oil pan quicker so under hi rpms all of the oil wont stay at the top of the engine and cause oil starvation

[mr1nutwonder]

@stingraystud : strange, with all the drain back holes in the head how could oil not drain back to the pan?

[stingraystud]

@mr1nutwonder with a high volume oil pump and high rpms, that sends a whole lot of oil to the top, if you ever take the valve cover off of an engine with a high volume oil pump even at an idle there is oil flying everywhere at 600 rpms imagine it at 6000 or 7000 rpms

[mr1nutwonder]

@stingraystud : but this is a 235-6, just how high of RPM is this thing going to see? maybe 3000.

[stingraystud]

@mr1nutwonder thats the part i could not figure out on this engine, it may be a performance engine but i doubt it

[mr1nutwonder]

@stingraystud : with all the years I have building engines, I never really found any advantage to painting the inside of a engine. on a street motor, the hot oil eats at the paint and it lifts off the cast iron. I have peeled off huge chunks in the past.

[stingraystud]

@mr1nutwonder i have always heard that you are suppose to use latex paint, i dont really know if it holds up better or not, i have never painted the inside of an engine during a rebuild, i was always afraid it would chip and flake off and get sucked up in the oil pump pick up

[fiatnutz]

One man's explosion ans another man's controlled burn - semantics.

[drtyfknmouth]

@fiatnutz Exactly.

[reniercosta]

Cool engine right !! guys I have a 250 inline and I wish to get a 6 speed on it is it possible ? maybe a t 45 or tremec ? what about the camaro 6 speed ?would it fit into the 250 ?the bellhousing is the same i would apreeciate it if you have any info .thanks

[ZULUBRAZIL]

I have a 1952 chevy truck with a 250 and a manual 5 speed from a C20. Im from Brazil and here is the best match.

I think is the Clark CL2215A, but not sure. C20 was a 90s gasoline Chevy truck with overdrive in fifth gear. Its a strong transmition because the C20 was a big truck. This transmition is hard to find because most of our pickups are diesel (D20) and C20 came with a 4 speed too thats not a good choice.

[jacktheripped]

If the bellhousing is the same the odds are what you have planned will work. you might need the disk from one tranny and the plate from another but it should work. Really check the bearing for fit. I'm having to do nearly the same thing for my race car. the motor is a Jeep version of the 151 Pontiac Iron Duke. it has a Chevy bolt pattern on the motor and I have an 80mm Saganaw 4 speed tranny. Motor came with a aluminum bellhousing and a T5 tranny with a blown 3rd gear.

[nuggmanrule]

nooo keep your old 235 and modifacate it some like i did its worth it

[osawill]

hi

please help mE i have 1955 chevy bel air whit tired 235 straight six and powerglide trans

my buddy had 1967 El Camino whit 250 straight six and TH350 trans both rebuilt 8 months ago

his get sweet deal on the 350 combo from crash car show and my questions is

this 250 combo bolt in ?? or I have to modify the crossmember different motor mounts?shift linkages

or is better rebuilt my 235 ?? I really appreciate any help you may have to offer me thank-you

[ryansiki]

Amazing to see a straight six like that. They used these things in trucks back in the early sixties because they were bullet proof. A real workhorse.

[ALVIE78744]

Wow! ....Cool!

[midnitesquirldog]

all the straight 6 engines gm ford and dodge had were awesome i heard alot of stories about those motors lasting 300,000 miles + the car would be rotted out and the engine and transmissions would be good still going to the scrap yard what a shame... most people would take the straight 6 out put a big motor in even if the engine was still perfect i had a 69 nova straight 6 289,000 on it still ran perfect when i sold the car...

[reniercosta]

@midnitesquirldog Hi , those engines are really strong for sure I have a brazilian Puma GTB with the 250 chevy as well ,how was the gas mileage on your Nova ?

[fritzr128]

This is cool---so you are breaking in the motor by artificial means ? manly to mate and break in the cam and lifters? Rings will come later

[jacktheripped]

all at the same time :) with fresh oil. Break them in on regular oil, not synthetic or the rings will never break in.

[flourburger]

Chevrolet continued improving the straight six from it's inception up to the 292 came in. That was through the 216 (babbitt) which was through 1952. The 235, 250 and 261 were improved on until the 292. That is about as far as technology could take the straight, overhead valve, six. It was a hell of a good tough engine. Junk pile? I don't think so. Generally, It is the engine of choice for old chevys.

[kennethrobinson11231]

@flourburger Don't call a 292 junk. A 292 would out pull a 350 V8 with the same load in a Chevy c60 truck. I had one years ago, and loaded with 8 to 9 tons of rock. It would out pull, out run not only the 350 chevy but the fords 330 361 V8, Dodge 360, International 304. The International 345 was hard to out pull I was close to him. A 292 pulling hard would run 100,000 miles if you change the oil and tune up when it needed it. 292 was the best 6 cyl. engine. Ford 300 was good, but not like 292

[k9forkids]

that 6cyl needs to go onto the junk pile...lol

[Totenhosen17]

I dont see anything wrong with it, sounds like it had good compression too.. Why toss it?

:D

[k9forkids]

How in the hell would you know it has good compression? there aren't even Spark Plugs installed? lol

The only use i could find is to use it as a boat anchor especialy when you can build a 350v8 with 100% more power at the same cost.

[Totenhosen17]

yeah, dunno what i was doin there either...

But still, you can hop up a straight six to have the about the same power as a 350, AND it would be much, much cooler.

but everyone is entitled to their own opinions.

[phrysk]

Eh... I have vehicle with V8 350's 327's 283's and the Inline 235, I like all of them :)

The 235 is a very good engine, but not for everyone. The 100% more power you talk about also comes with 100% more fuel consumption. But I do enjoy the power of a V8 too, and I say V8 not specifically 350 because my 283 and 327 have lots of power too.

[autophyte]

I've been told that the new oils don't have zinc in them, in order to prolong catalytic converter life,resulting in rapid wear of flat cam followers (lifters) in engines, especially during start-up and break in. Is this true?

[EdwardPack1988]

yes it is. Thats why it is as good investment to get as roller cam. Valvaline makes oil called VR1 racing oil with zinc and so does royal purple. i also been told shell rotella diesel oil also has zinc and is safe on OLDER flat tappet engines.

[autophyte]

Thanks. I can get Rotella diesel oil. I don't want my vintage car engines to wear out prematurely.

[cas111498]

ok pull some shims already, ha ha .

[PALLADINARC]

how ironic...a new truck doesnt do much better even with all its "improvements"

[PALLADINARC]

what is the bhp and mpg for a 235?

[1093T]

About 25-28 highway, and about 15-16 in town.

My uncle gets about that in his '54, but he keeps it in near new condition.

[EdwardPack1988]

New cars today don't get any better fuel milage than older cars. Infact cars during the 20's averaged around 25 mpg, while today avearge is about 22 mpg. Almost 90 years later and cars are getting worser fuel milage. Thats ashame.

[roddinron]

Actually, when you compare the number of horsepower you're feeding today compared to then, it's a GREAT improvement. I'd hate to think of trying to drive a stock engined 20's vehicle on the highways of today.

[drtyfknmouth]

Yeah, a model T Ford had a 177ci 4 cylinder with 20 hp and a top speed of 45 mph. No AC, no automatic tranny, no power anything, plus when considering the weight difference I'd say maybe it could be a little better but we're still WAY ahead of the curve :).

[LeviMan2001]

no auto tranny, but an interesting fact about the tranny, is that it's a planetary gear tranny similar to modern auto trannys except shifted manually and no torque converter.

[drtyfknmouth]

I look at how a transmission works and think about how smart the guys that came up with them were! People who don't know what all goes into making them work really can't truly appreciate that. Of course harnessing multiple explosions to cause locomotion in a desired direction is no small feat either. :)

[LeviMan2001]

I know, it's truly amazing! The people that I figure must be insanely smart are the ones that design computer motherboards, those are stupidly complex.

[freshvu]

@drtyfknmouth I agree, but it's not an explosion :) Bits of motor aren't flying through the air with every combustion

[drtyfknmouth]

@freshvu You say it's not an explosion, but you DO agree it's combustion. Explain what happens inside a cylinder during the power stroke, then try to explain to me how the gas isn't exploding.

[fiatnutz]

@drtyfknmouth - Tha power strock is a rapid oxidation process. Any oxidation (burning) process is either controlled or not. As the process begines the piston is down in the cylinder about 20-30 crankshaft degrees. The compression helps to mix the air/fuel mixture and aid in the burning process.

[drtyfknmouth]

@fiatnutz Exactly. He says it isn't an "explosion" because parts don't fly everywhere, but he says it IS "combustion". My point is that it's the same thing, it's a controlled explosion. Being such, nothing flies apart when it happens, which is how you harness the power of a series of explosions to create usable power from fuel/engine. I don't think he understood what I was trying to say. Thanks for helping me explain my point. LOVE your videos man! Keep em coming!

[freshvu]

@drtyfknmouth It's simply not an explosion at all. I think you need to look up the meaning of explosion. It's a controlled/uncontrolled burn.

[drtyfknmouth]

@freshvu Go to merriam-webster's website, type "explode" in the little white box, hit the enter key, read their definitions, and THEN, try, as convincingly as you possibly can, to explain to the rest of us why you're right and I'm wrong. I dare you.

[fiatnutz]

@drtyfknmouth - Check out this video here on YouTube:

The Secret Life Of Machines - The Internal Combustion Engine Part-1 John...

[drtyfknmouth]

@fiatnutz Alright, at 3:54, he says that what's happening is NOT an explosion. THEN, just after 8:00, he tells about the water jackets essential to help cool the engine due to the "explosions". Webster's definition- Explode- [to undergo a rapid chemical or nuclear reaction with the production of noise, heat & violent expansion of gases]. I'm not arguing that it isn't a controlled explosion, but my question is, who's right? Isn't it all just semantics?

[LS100TA]

@fiatnutz Do agree, engine burn, do not have explosion in the cylinders

[CJinSeattle]

@drtyfknmouth

Combustion is not the same as explosion but the general thought still stands. :)

[drtyfknmouth]

@CJinSeattle Webster's definitions: [Explode- to undergo a rapid chemical or nuclear reaction with the production of noise, heat, and violent expansion of gases.]

[Combustion- : a usually rapid chemical process (as oxidation) that produces heat and usually light.]

The beautiful rumble of an engine, the heat it produces, the force that drives the pistons, & the light of the crackling fire from the pipes. Sounds like they have a lot in common w both definitions, but I've been wrong before.

[CJinSeattle]

@drtyfknmouth

True that. I get it. I thought the same thing. Then I read that explosions are the equivalent of detonations in an engine which we all know is a big bad thing. :D Diesels DO explode, since they have no spark plugs. That's why they're built so much more durably. "The beautiful rumble of an engine, the heat it produces, the force that drives the pistons, & the light of the crackling fire from the pipes. Sounds like they have a lot in common w both definitions." I totally agree.

[drtyfknmouth]

@CJinSeattle Like John said, semantics.
