I started my car up today for the first time with the new motor. I love it already and i haven't even got to drive it. It cranked right up first try. And man it sounds good. I went with a Comp Cams XE-R 238/242 on a 112LSA. The lift is my secret It goes on the dyno tomorrow morning so i'll post some numbers for you guys tomorrow and i'll be taking the video and i'll try to get it on here sometime next week. I need to make a sig with my mods but this is what i have. Direct flow air lid,slp 85mm MAF,slp smooth bellows,home ported stock TB with bump stop mod,stock LS-1 intake(I know i know i'm working on the LS-6 intake) , Comp Cam listed above,Comp pushrods,Titanium retainers, Comp R lifters,Comp 918 springs,Stock Heads,Mac mid length headers with the big welds gringed down,H-pipe with two bullets turned down at axle,TB by-pass, !AIR, !EGR, Free Air mod, !A/C, SLP ported oil pump, and of course the Eagle 383 stroker kit.

I'm sooo happy with it so far. Hope it puts down good numbers. This is my first car i've had a motor built in. The car is a 99' SS M6 by the way. I'll get those numbers on here tomorrow hopefully. And might i just say that when the car cranked up i went Sorry had to make a post i'm kinda excited here. Anyways thanks for listening to me ramble on.

 

You gave the lift away when you told us the duration and the XE-R lobe. It's readilly avalible on comps website. Good luck with it, I hope it makes good numbers.

 

and

i'll be awaiting your graph

 

im sure you have adjustable rockers with the comp Rs....

 

cam is custom grind and no i have stock rockers that have been shimmed

 

Yeah But You Listed 918 Springs, So I Doubt They Are Over .600

 

Congrats on your new motor. Did you build it or did someone build it for you? If so then who? Was the price reasonable?

 

ok lift is actually .609/.614. i had someone build it for me. after parts and all labor and TUNE it came to $6300. So i don't guess that's to bad. Should go on DYNO Monday. I'll get numbers and vid on here next week. I'm sooo happy with it so far.

 

you mentione stock heads, are you planning to go with some ported heads in the future, you might not get the power you expect from stock heads on a 383.

also, the comp 918 springs are good for about .600 lift, i would recommend some dual valve springs for this much lift if you want it to be safe.

good luck with it and make sure to post the video too..

 

I agree with the loss of power on stock heads on that 383 with that cam. Lets see some numbers and find out.

 

Congrats on the stroker!!

I would personally swap out the 918's though for some double springs good to 650 lift. A broken 918 could be disaster for a motor. Those lobes spec out at .605/.610 so you got a little extra lift from Comp

Let us know what the numbers are, good luck!!

you have a ticking time bomb with the stock rockers...
good luck...
