help, lunati 382 stroker kit questions...
all other things being equal, my stock bore ls1 with heads/cam bolt ons pulls 396 rwhp, if I get the lunate stroker kit, what CONSERVATIVE bump would I get in HP and tq using the same heads and cam header etc is it worth the money? Also, could this be used as the basis for installing a s/c like the vortech since the bottom end would be stronger? what are the pros cons of going stroker?

Before I had my stroker built ..I asked the same questions. :yesnod: As a rule of thumb I'm told the kit is good for about 1 h.p. for every cu.in....and depending on the cam, even more. I went with the Lunati 232/236/-575/578-112 cam and increased the RWT over a 100 ft.lbs. :eek: The tuning has alot to do with the final result as well. Spend some time with your tuner and come up with a plan, a strategy on what your looking for ..There are lot's of options.:yesnod:
The main reason for the kit is the stronger forged components!! The crank ,rods and pistons are all much stronger now and the rpm range is considerably higher. :thumbs:
Check out my homepage for videos of my new Lunati 382 stroker..:D

can you post a dyno graph after stroker install and tune or at least what was your final rwhp number and rwtq? graph would be nice to see area under the curve also, what is your rev limiter set to?

The kit is not good for a s/c IMO. Although you have better internals, the compression is still high. You might not see a lot of boost. You want 9:1 or 9.5:1 compression for one of the superchargers.
I would say expect a mild increase in hp but a good increase in torque. Your car will be a lot faster even though the peak numbers might not be that much greater.
What size cam are you currently running? You can go bigger on a cam with more cubic inches.

Tony, whatever you do, make sure you go with a reliable engine builder if you go the stroker route. Please do not try to save a few dollars and have some unknown engine builder build this for you. Stick with an engine builder that has a TON of LS1 experience as this project could lead you down a road you definitely do not want to go down again if you don't do it the right way. When engines arent built perfect you end up with a detonating, oil burning pig.
Also, your heads would be fine on a stroker, but I would definitely go with a larger cam and stronger valvesprings.
Drop me an email if you want to discuss a path to getting where you want to be with your motor.

Not to steal your thread, but....

The Stroker kit of course will a produce greater torque due the increase in cubic inches.. :chevy

I've been thinking about stroker lately instead of going the FI route. I know the cost difference between the 382 and 427 is wide, but what about the power increase. Is it more cost effective to just go with a 382 or 387 or just save up and go all out with a 427?

Check the Agostino site and look under their short and long block packages, Cartek and MTI have numerous packages as well, it will give you a good idea what is involved and how much $$$-I went with Agostino 436ci----

I also believe that they have a dish piston that you can substitute for the flat top if you are going to run FI.
If you need any help at all, give me a ring. I am more than happy to help. You can also read a little more about the kit on my web site.
