383 strocker?

I just wanted any information on a 383 stroker. i have looked at a lot of camaro owners pages and a lot of them have said a 383 stroker. Does this engine really kick out a lot more power than the standard 350 in the Z28? if anyone has one or knows anything about it would greatly appreciate it. Also how much does it cost?

well depends on how dynamic of a stroker you want.. a run of the mill stroker will run about 450 Hp.. and run you about 3-4 grand.. unless you can build it yourself. they are also a high rpm engine.. where your normal 350 will turn 6000 rpms safely, a 383 can turn 7-8 k with no problem.. just depends how dependable and how much money you want to spend.. it also stands to reason wether you want a FI motor or a Carbed motor.

i am buying a stroker at this moment.. that allthough im getting a good deal on.. i am still paying a high price for.. when all is said and done i will have about 8 thousand dollars or so in the motor. that will run (if my math is correct) 655 hp @ 8100 rpms.. but the motor will be safe till about 9800 rpms...

of course this will barely be streetable let alone a DD..

if you have a lt1, there is a guy on EBAY that for about 4500 bucks will build you a FI 383 stroker and put it in your car if you take it to to his shop in indiana.. as long as there was a LT1 int he car to begin with.. and he will do all the dyno tuning and everything for you for that price.

just gotta figger what you want out of the motor and what you need. also what you are able to spend!

hope this helps!

Thanks. i didn't know they were that expensive. Keep me updated when yo get yours finished. Love the quote about ford hitting fords. lol

it all depends how much you want to gain... you can do a stock setup just a steal stroker crank reuse your stock rods and get the stroker pistons fairly cheep and still run it with maybe larger injectors... but that wont give you gobs of power probably like an extra 100hp and 150tq for about 1500-2000 bucks if you tear it down yourself then take the new parts to a machine shop have them assemble the short block balance it and everything then you finnish putting the top end back on...which really isnt to bad of a price for a NA power increase but if your gonna do it you might as well go all out get forged parts new heads and cam to match the cubic inches you just added... really no point in tearing the motor apart notching and clearancing it for the stroke and cam and then not make it atleast a little wild.. but still probably one of the best bang for the buck power adder besides boosting the motor or spraying it... a stroker motor will still run pretty much like your stock little worse gas millage but alot more go

We have various LT1 stroker kits, starting from $1599.99, and assembled short blocks from $3399.99.

I thought shorter strokes could rev faster? Makes sense intuitively as a shorter stroke at a given rpm will have a smaller maximum piston velocity...

My buddy that just built his 383 said if he could do it over again, he'd invest the money from the machine work and crank into head work, etc.

they are also a high rpm engine.. where your normal 350 will turn 6000 rpms safely, a 383 can turn 7-8 k with no problem.. just depends how dependable and how much money you want to spend.. that will run (if my math is correct) 655 hp @ 8100 rpms.. but the motor will be safe till about 9800 rpms...

I have to disagree here. In my experience a 383 wouldn't be a high rpm engine safely. They are usually a torque engine made below 5000 rpm's which is why they are so widely used on the street. This is due to the increased stroke (3.75") over the 350's (3.48"). I think you may want to check your numbers, I've never heard of a 383 peaking that high in the rpm range and running safely to almost 10k rpm's. If anything the 350 should turn better rpm's with the same money and for that kind of rpm's I would think you would want to decrease stroke to increase your HP like a 3.25" stroke (327 ci) or 3.00" stroke (302 ci) crank.

I could be wrong, but it would be news to me, and if anybody thinks I'm just way off here feel free to chime in. Just thought I'd chime in not only for Josh but for xavier as well.

I believe you're 100% correct. I keep typing additional info, but you've pretty much got it covered.

You guys are right....383 will rev less. Longer lever means more torque and slower speeds. Somebody should do their homework

well all i have are the data sheets straight from Hendrick Motorsports Inc.

i have heard that stroker motors can be high or low rev. depending on how their built..

in the short track scene i have yet to hear of a 383, or any other motor for that fact that was not turning some gobbbs of rpms. i have never heard or seen short track motors making power at less the 6500-8000 rpms.


all's i know is when i put the deposit down on my 383, the warranty sheet i recieved Via USPS says that i am garunteed 620 hp, and up to 9950 rpms, anything over the 9950 rpms will void the warranty.

alls im going on is my short experince in the short track world, and my contract for the motor i am getting from a nationally renound race engine manufacturer.

i have no problem if i am wrong, and i could very well be.. please correct me.. would rather be right and eat some pride then be spreading the wrong word around.

Well that's all we're trying to do is just get the info right. I don't know the circle track world that well but I do know a lot of them run long rod (6") 350's too vs the 383 because you get better rpm's. Seems like an awful lot of rpm's especially for a 383. Do the Nascar engines even turn 10k?

[zspot98]

You must have got a great deal because I have never heard of any engine builder creating a warranty for up to X HP or X RPM. I've know of three guys that bought 383's and 2 that bought 427's and none of them were given that type of warranty. The engine builder just states that the engine should hold up to X hp, but I've never seen a warranty for that. So if you did get one like that, good on ya man. Check out these thread's and see what you think about the statements made by your engine builder and the opinions of the site members...Mike

Pretty sure they are usually between 8000~9000.

Yeah, NASCAR motors will see 10K for the short tracks, but they're 347 cubes.

That is the exception though, not the rule.

Usually they'll max out around 9500, and yeah, I'm splitting hairs...

10K is usually reserved for F1 motors or things that ride on two wheels.

Yep, I know from personal experience that things on two wheels @ 600cc will turn 13k and that was 10 years ago, now they have some turning 15k. Requires special anti-foaming really expensive oil too!!!!
