yea and you need a diffrent water pump
Maybe I'll swap my heads with my mom's EXT, she'd never even know. :devil: As for the intake, is sounds like what I have is alright then, and the cam will have to be of a custom grind.
When you say everything off Camaros, do you mean LS1s?
You can swap just about anything between any of the GEN III family of motors (4.8, 5.3, 5.7, 6.0). Heads, cam, intake manifold, exhaust manifolds, etc will all physically bolt to any of those blocks, but there could be interference/clearance issues based on what application you're working with.
For instance, you can't run F-car manifolds/headers on the NBS trucks because the simply don't route correctly to clear the frame. The intake manifold is the same--the LS1/6 intake will physically bolt to the iron blocked motors, but you have to make some modifications to the accessory brackets to get everything to work properly.
I swapped to an aluminum 5.7 LS1, and used all of my truck "peripherals" (intake/exhaust/accys). Everything lined up perfectly except for one bolt hole on the A/C bracket not having a corresponding boss on the block. Since there are 4 other bolts, I'm not too worried about it. :D
Good luck!
yea ls1s Oh your truck would be a runner with the lq9 heads i think they lower your compression a point. not sure
Sweet deal. I'll start looking for lq9 heads then.
These are the equivalent of LQ9 heads right?

Would my 5.3 heads work just as well Ported and Polished?
She might get suspicious when she has to run premium gas because of high compression.Quote:

No those will bump up your compression. The combustion chamber on them is 59cc or 58ccs i cant rember but yea you dont want those.
No to the lq9s. Does airflow research make heads for the 5.3?
