All I have left to do is get the cam, machine work, heads and bigger injectors. Then drive down to Futral and get it tuned. I'm gonna go ahead and get the cam and the patriot dual spring kit within the next few weeks. I'll get the rest when I get my taxes back.

 

im gonna go with around 355rwhp.

 

Sounds about right to me. Prolly knock on 400's door.

 

Voted for the 360 I put down close to 330 with a 5.3 and a slightly smaller cam true duals and dynatechs so you should have close to 360 IMO. Put some juice on it too for good measure

 

i'd have to say somewhere's around 360 also...

 

Keep em' coming guys!

 

Without dyno tricks or a Dynojet I'm gonna say about 360-365 at most. I did 345rwhp on a high CR head/cam 5.3L. Then again tire/wheel weight will play into it as well as 2wd vs 4wd.

 

I said 355-360 rwhp....

 

365 RWHP... my expectation for my '86 is a little less.

 

ttt....

I just seen Scream's dyno with his bolt-on LS1 w/ a 224/224-112 and STOCK heads and NO dyno-tuning and he put down 354rwhp/357rwtq. Oh yeah, that was also with the truck intake, which I plan on using as well. Seeing good numbers like that with no heads or tuning gets me pumped up on the potential of this LS1 build-up!
