Default Need help!

I have a fairly new LS6 and the only mods I really have done to the engine are headers, SLP cold air induction kit, exhaust and got it dynotuned. It already has 336rwhp and my question is if I get it stroked out to a 383 and I put a 92/92 setup on my camaro along with probably either 205 or 215 AFR heads what type of power am I gonna be looking at? My transmission is an automatic. Also had another question, I saw a thread on here of a guy that stroked out his ls1 to 383 and put a ported 90/90 setup on his with ported
AFR heads and I believe a cam as well, my question is with my LS6 engine would I end up having the same amount of hp as the LS1 if I did the same mods as him or would I gain more seeing it is a LS6? Any insight would be much appreciated!

500+ rwhp can be had with a 383ci. Cam choice will be a big factor. Heads/cam and the fast on the 346ci will get you to the 450(+-) range. Also don't forget to match a converter with your cam.

LS1/LS6 blocks share the same bore so a LS1 can make the same power as an LS6 if they are prepared identically. The difference is the bay windows cast in the LS6 to improve windage. Some believe the LS1 bock is slightly stronger (rigid) however.
