383 Chevrolet Low-Stress Breeak-In on Simtester

[afcarrjr]

i think thats a way to make sure you did the bearing right every motor i built and everyone that i know that builds a motor goes in a gets ran car or boat

[allegrobas]

Stupid music detracts from the sound of the running engine.

[DSMeclipsegst]

i heard 383s tend to over heat alot!! is that true or is it just a bad built one that does?

[chevyman8329]

nice elevator music!!!

[sideshow45]

engine has a small oil leak.

[pismo10]

Why do you not close up the motor first and then simtest with it's own oiling system.

[kearneytyrone]

HI can a 305 becom a 383 stroker my 305 is a TBI

[fiatnutz]

@kearneytyrone - No, the bore on the 305 is too small, but you can put the 400 crank and make it a stroker.

[kearneytyrone]

@fiatnutz cool so do the 305 have to be homed for that

[fiatnutz]

@kearneytyrone - If you the block needs to be machined oversize, yes and yes for a rering job as well.

[kearneytyrone]

@fiatnutz o i live your show

[kearneytyrone]

@fiatnutz o i love your show

[420chevy420]

@kearneytyrone I think the block would have to be notched for the 400 crank cause it will hit the walls

[kreigsmann]

i was not even aware they even made a machine like this

it is a great idea

evolution in the engine rebuilding industry.

what rebuilder has them i wonder?

[Warblade118]

Cool to see things in action. You realize that at 6000RPM that crank makes 100 revolutions in 1 sec?

[kyligz]

eeehrm.

Just so you know, never ever run a new engine on idle. It needs compression to break-in properly !!

[SmashMat]

@kyligz yes when HOT...this one run's cold. just the best way to be sure the engine's ok

[scott93257]

You should let me compose you some new music :) It's what I do for a living... message me in regards to it...The music is not bad...but a bit dated.

[PistolPete2]

In years past, we had nothing as fancy as a Simtester. We simply pulled

the vehicle around for a few miles and let the engine turn over with the

ignition off. It worked pretty well.

[SuperRhino22]

love the elevator music lmao... but sounds good :)

[XxMusclecarsxX]

loll my dad doesnt make a break-in for his engines he builds 600hp 383 and 406 and bang wot 9.57 @ 140 makes me laugh.

[revoguy]

@XxMusclecarsxX Ur a Dumass

[newengland72]

What about the piston rings?

Don't you have to get the cylinder pressure up to seat the rings, or is this more to break in the valve-train?

[VegaWgn]

ebay has you all beat

[isaacpbrown]

i love in Piggott AR and i know someone here that builds them that can get the COMPLETE 383 rolling Asmbly for $650

your block/heads with Machine work + the Rolling Asmbly = $850

[marcuskicker]

can buy a stroker short block from places for cheap.......$999

[screaming355]

this is pretty neat olny problem is u get oil all over you motor

[BHARMS2]

brake parts cleaner will cure that problem

[k9forkids]

or you could just install very weak valve springs to break in the cam

[pmanson0624]

thats interesting, plus its better to test it and work on the engine before you actually install it

[RenzeZielman]

I fill the last liter of oil from the top, covering everything with oil before closing the rocker cover, and let it run on the starter for a minute with no fuel nozzles, so it runs without compression untill i see oil coming out of the tappet lube holes.

[jerrydoubleu]

HEY, I KNOW that music--porn music from Behind the Green Door! :)

[joefacc]

@jerrydoubleu

I was thinking the same thing. Sounds like porn music from the 70's.

[fiatnutz]

It does, this gets get the pistons and rods in the right orientation and allows for cam initiation. You still have to do the 2000rpm run-in for 20-30 minutes when you install the engine. I find that engines start faster and easier when run on the Simtester, plus I can check for oil leaks.

[angelicricky]

i have a 350,where do i buy a kit for it to make it a 383? how much what do u reccomend thankxs

[Codythecartaker]

welp if you have a complete 350 a crank,rods,pistions and bearings will cost 900to 1900 i belive OR just get a 400 crank and rebuild your motor id go that way BUT if you want New go to jegs . com or summitracing . com....Good stuff there but can get spendy

[1pollo1rabbit]

Better off buying the stroker kit from jegs or summit.A stock 400 crank has to be turned down which weakens it plus the cost of machining.Rotating assemblies come as matched sets.less headache.

[digzie1]

northern engine parts..

[Drue192]

You cant just make it a 383 to do that you will need the block bored to 383 CI. New Pistons, heads, etc. It would be alot easier on your part to buy a 383 then to make a 350 a 383.

[1pollo1rabbit]

You also have to clearance the block and file some material of a few of the rods to clear the camshaft. If you don't the motor will have some serious damage

[arizonaresident1]

You don't need new heads to make it a 383. You need a 3.75" stroke crank.

[chanceforegren]

get a speedway motors race or street rod catalog and look at the chevy engine section, you can find stuff from scat and callies

[emzarino]

@fiatnutz  What does a service like that cost?

[guitar1111111]

i thought higher cylinder pressures seat rings better?

[ezcondition]

that's how you break'em in the right way, but the machine is costly, and not everyone has one. sometimes big engine houses will have them, but they don't do custom public builds.

[zenithbay]

Damm...That's a great idea !

I did'nt know there was such a machine to do this..

[ganee6a]

i love ur vedios man...u r great

[jfl187]

how long you run it?

[blazingtortoise]

deadly

[chevybro03]

great idea, i must say!

[enginemasterbuilder]

we bult one of these from a tractor transmission attached to a pto shaft and it worked just like yours except that we had a base pan on
