[morderca95]

Is that a Roadrunner ?

[Bellefeuille66]

i have a 70 challenegr with a 493 and i was wondering how exactly 493 cubes in made? what rod length and what bore and stroker because ive never had the engine opened up and i bought it from a dead guy and im not the best with math..so any hep?

[lastofgenxxx]

Damn now i cant get your video out of account any suggestions genius?

[lastofgenxxx]

And yes you are very right about this country! Move!

[lastofgenxxx]

And I dont see any of your links and dont need too!

[warlock451]

Ok. A cold weather block is not an engine thats been laying around in a bar in canada. These rare blocks are commonly referred to cold weather/industrial blocks. There is more rib support cast in the side of the block for added strength and rigidity. They came as 413/426/440 displacements. The heads Are Max Wedge Ported Edelbrock VICTOR 440 heads. And yes, the cam is .700" lift.

[lastofgenxxx]

What is a cold weather bock? Or block never heard of that? Does that mean it sat in a barn in canada? And damn what is victory-max wedged heads? Really? And that is the tame 700 lift cam! Are you sure you know what you have there?

[warlock451]

@lastofgenxxx I am very much aware of what I have. I was one of the engine builders and I selected the cam shaft. The cam is indeed .700" lift. The engine actually idles at 1200rpm. has a power range of 5000-7800 RPM. If you need more proof, watch the video link above. This engine propelled a 3500lbs road runner to a best of 9.80 @ 139 MPH.

whats an engine like this cost to build? nice work btw! one bad engine!!!

[Skeletoil]

r u running a timing belt? won't help with the oil pressure just curious. now we're running evacuation systems for the crankcase, pump or pumps, good for fifteen hp max rpm. that was awesome on a homebuilt stand

[Joker28th]

dam man it sounds fuckin amazing

[DYNO323]

why does the exhaust seems to ve closed???

ive allways wondered that

[warlock451]

@DYNO323 Those are Defuser disks and they tune the sound for the Supertrapp muffler.

[Joker28th]

dam what kind of mufflers are on it that thing sounds really good

[warlock451]

@Joker28th Those are 3" in 4" out Supertrapp mufflers.

[Giftied]

hey do u think this motor would fit in that dakota in ur other video

[warlock451]

@Giftied Man... I would love that....That engines in my fathers road runner now, but I pretty confident that it would fit.

[moosemobile33]

440 bottom end will prob turn faster than that but the heads wont let it

[warlock451]

@moosemobile33 The heads are Fully Max wedge ported Edelbrock 440 Victor Aluminum Racing Heads. Valves are 2.20 Intake and 1.81 exhaust. The engine will turn over 8000.

[moparmaniac666]

great motor, whats it going in?

[warlock451]

@moparmaniac666 Its in a 1969 sox and martin plymouth clone.

[meirace]

7800 rpm nice! whats been done to that beast?

[Wildkkat1]

I think to much oil pressure could wash the bearings! 80 psi. is plenty! Let us know what it turns, thanks!

[yumyumsashimi]

That is bad to the bone! I have to settle for my 68 Imperial it has the 440 in it stock with 118,000 mi on it. I love a built engine so I will do a mild build just to enjoy and use this car to tow my boat.

[pimpmasterpercy]

wow nice. I now know the supertrapp exhaust tips can work on my 454 fiero. Was wondering if they might quiet a big v 8 enough to drive on the street.

[ryan112976]

Nice engine, turn that oil pressure down, 10lbs per thousand rpms is a good rule. Save some horsepower! (and your oil pump drive shaft!)

[darokkz]

very sick. my wedge builds a ton of oil pressure too, 80psi at idle and about 100psi crusing down the highway. And its only a stock internal pickup hi-volume.

[moparrr07]

theres no way you would need to turn 7800 rpm with a 4.15 stroke, your running it out to far

[warlock451]

Bottom end is studded and girdled... Operating range is 5000-7800 on the cam... The engine performs very well flawlessly at these RPM's as it should. No reason why it shouldnt be able to spin that fast...as thats what its intent is.

[kloveh]

Very nice.

[hondakil4]

when i heard this rev i think i might of jizzed in my pants

[HUMBOLDTG35DRIVER]

BAD ASS, Those headers look a little small for the motor tho. I want to build this same motor just 11:1

[warlock451]

Glad u like it. Those pipes are 2" its kinda decieving but the motor will turn 7800 RPM with out any problems

[OwnzNubFace]

A 440 going to 7800? yea.

[warlock451]

Yes it does

[73sebrougham]

@warlock451 best believe she goes up there take my 9 sec GtX runs 8 grand all day

[MahoganyBrother]

Thanx for the stats. That's so ironic in the vid response because I'd like to put one like it in a '70 Dart Swinger 340 Hurst if I can get one - wow lol

[MahoganyBrother]

What type of cam+lifters and RPMs you runnin?'

I want an engine JUST like that! Was it a Max Wedge, 440 or a 383 at first?

[NoLongerFooled]

Jesus H Christ that thing is huge!

[jdcauthr]

what are the things called in the back of your headers??

[warlock451]

supertrapp mufflers

[darokkz]

Awesome!
