Gonna stick em on the new 5.3L setup.

I didn't really feel like taking the time to find a good 6.0L for the swap as I want my truck back asap and I'm thinking that with the 6.0L heads I wont be making a ton less HP as the main diff. is just cubes now and that wont account for too much HP. The main thing is the lowered compression. Now I can run boost to achieve the same HP level and be safer than before.

My main goal with this truck is to make great HP but keep it at a safe level and drive the **** out of it. What good is peak power when you can't get on it for fear of breaking? LOL

Anyway, is there any way I can calculate what my new compression ratio will be with these heads? If i start off with 9.5:1 then is there a simple formula I can use? I don't have the specs on either head as far as CC. Any advice?

 

Ive heard 8.5-1 with those heads. I could very well be wrong, but that is what I remember. Im thinking of eventually doing the same thing. Please let me know how it goes. I havent gotten them yet since Im not sure if I should spend 1K more and get the whole 6.0, Ive heard it is more stout than ours.
