383 stroker
I am interested in doing a 383 stroker- I know these projects can get expensive with running into extra things, so to those that have done it, what all should I expect to run into beyond the pistons, rods, and crank? What kind of power are guys making with 383's? Thanks

Look towards the upper r.h. corner of this page, you will see "Search". You can search the forums with this (they even have an advanced search). I bet you can find tons of info on "383 stroker". The latest hot rod mag has a write up tha shows for around $4k, you can get 500 hp out of an LS1

Chris and Doug at ECS are building a 383 stroker for my '04 C5. They said it would be ready in two weeks so I will post my hp and tq numbers once completed. There are many factors that contribute to final performance numbers, i.e., heads, cam, etc. My setup is conservative because I plan to run it on the track during HPDE sessions approx. 6 times a year while being a daily driver. I hope to see 450+ RWHP with a high and flat torque curve.

I already have AFR 205 Heads and a G5X3 cam making 430rwhp- was hoping to be able to break 500rwhp, or get close with a 383. I did do a cursory search I swear! I couldnt find much info from the C5 guys.
I priced the Eagle Crank, rods, and pistons at just under $2500, and my mechanic said he would do all the work for $1K, so I think $3500 would be a great price for the power, but I also need to know what else is going to be needed (Oil pump, fuel, etc). I may make this my mecahics' winter project while I am in Germany for Christmas

Most shops charge 1500 just to R&R the block.

my 383 made 490 rwhp and 460 rwt with Patriot 59cc heads and a 231/237 112lsa cam. I did use a ported oil pump and doulble roller timing chain. Jerry BTW, 1 7/8" headers killed the low end torque by as much as 37 ft lb. I had to put my 1 3/4" back on with the Dr. Gas X pipe

I believe that price is without core, so it would be 5k minus whatever you can get for your take-offs.
Wouldn't blame you for going the DIY though. Your guy with the shop sounds like a blessing, but I would also make sure you or he has a good machine shop lined up. You'll need to get the block decked and notched (for the stroker crank I believe), and have the heads cleaned and decked.
Hey guys, would you also get the block "dipped" at the machine shop? I'm still working with old school knowledge on the bottom end. Back in the day we would always wait until the shop changed out the bath with new fluid (every month or two) before sending in for dipping.
This is something I'd like to be doing myself, whenever I get the money, so let us know how this goes...
Good Luck!

I know, they probably could never tell the difference, but I just don't play that way... Other than that, I really like the LS2 402, and yes it's all forged, at leat the way they come from Scoggin-Dickey and SLP they are, dunno about anyone elses.
Again, let us know how it goes, and good luck!
