How come we don't see more 382 strokers? With Eagle parts being affordable how come more people don't just build 382's rather than paying big dollars for resleeved blocks or pay for a new block and add the extra weight of an iron block?
I'm trying to figure out if it's worth it to stroke the motor with H/C or just stick with stock cubes and H/C.

if the numbers are disapointing their setup wasnt planned right from the begining.
youve heard the saying, there is no replacement for displacement.
you WILL make power with more cubes, but plan your setup from the begining.
you need a good set of heads, the right cam, the right exhaust and intake etc.
people dont do it because the average person doesnt want to spend 2-4grand building up their motor at once.

Well as we have seen recently 346 stock cubes max effort are achieving close to 500rwhp. In general poeple go the iron way as it has more cubes and is capable of achieving higher power levels more easily.
Personally I favor the 382/383 cubes because of the weight factor and if properly put together, those combos are capable of over 500rwhp with plenty trq down below.
Also it has to do with the fact that a 382/383 needs machining of block for clearances and is usually in the same price range of an iron block that doesn't require a core.

I like mine.
Eagle crank, Eagle H-rods with L19 bolts, Ross pistons. No dyno #'s yet, but the first track times weren't bad for no tuning time.
We literally got it running on a Thursday, loaded it on the trailer, and I took it to the Thunder Shootout on Friday. ![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)
I would much rather have a few less horses vs a 408, than an additional 80-90 lbs on the nose of the car.

I weighed my car the other day and it came in 3640 with nobody in it and I have done some weight reduction (front/rear bumper supports removed, z06 rims, rear seats/setbelts removed as well as some various plastic peices, not to mention headers are lighter than manifolds etc etc. )with me in the car it weighs 3860 lol
![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
To compete at a track I will be forced to spend alot of money on even ligher rims, seats, k member/a arms , hood, and then I might even have to take out my comfort items like powe rsterring AC/heater core etc.
Now my block has been/is extremely durable but who is to say an aluminum one is not plus nobody has really experimented with a 383 to see what a max effort is. shoot nobody has really done a max effort 408 for that matter.

My car is running great with my stroker setup and I am forced to run cats! (see sig)
Should be in the 128-130mph range in the spring on motor.
No dropped sleeves to worry about, no added weight of iron, less expensive.

480rwhp
440rwtq
Daily driver 92 octane
383 Callies with LS1 heads
No extra weight with the iron
I think lots of people are happy having 550+hp 383s...

Properly built, I do not see why this "offset" stroker wouldn't make lots of power.
Thing is, this type of stroker is short on rpm capability, due to it's stroke /rod combo, it tends to put a lot more stress on the cylinder walls, reducing it's longevity and adding to the oil consumption factor in LSx motors.
For some application though like trucks or really heavy cars, this can be a trq monster ticket.
All this would mean a light rod, piston assembly which would cost mucho mucho dinero.

I may be wrong here but I think a lot of people lose sight of the fact that while a 4.00 stroke may be 1/8 shorter than 4-1/8, it is really only .0625 different as far as the centerline of the mains to the centerline of the rod journals. What do you think?
Not only is there more side loading there is also piston design compromises with the longer stroke. You are also limited in piston choice with the 4.125 stroke vs the 4 inch stroke setup.
I would stick with the 4 inch stroke. It tends to make a little more power in the 4500-7200rpm range and you also get a stronger piston that will better handle spray or FI.

That being said, the point I was trying to make was that in my situation, I can't justify the large difference in cost to gain the "relatively" small increase in power/torque...I guess it all depends on what you're after...
My car will see the strip, but that is not what it is being built for. The highway is my focus

Do you hear more piston slap noises because of the shorter skirt forged pistons?
Do you have more engine oil consumption compaired to stock ?
Are there any downsides of the 383 stroker other than high cost that you have learned from personal experience?
Thanks
