Cam selection: 5.3's milled for 11:1, 3500 stall, 3.23 gear Looking for the strongest NA cam I can find to match up with these other parts in my A4 car. I know the cam will have to be on the smaller side because the heads are milled. Also, please let me know how 3.73s would perform with the cam in question.......thanks

Your 5.3 heads are milled .030"? That would be like .060" for a 5.7 head.
Or were you just stating that the valves on the 5.3 heads are already .030" lower than the 5.7s?

5.3s should only need about .010" to bump an otherwise stock LS1 to 11:1. The factory 5.3 chambers are 61.3cc vs 66.7 for the 5.7 LS1 heads.
I'm not trying to bust your chops about your heads I'm trying to understand exatly what you have. I have an LS1 that I'm building a set of 5.3s with 2.02s and I'll be running a Futral Motorsports F14. My 5.3 heads were millied about .007"

, as per my request and invoice from TSP, they're "cut for 11:1 compression". Take it from there.... Trending Topics

You need to find out how much they're really milled. like I said, 11:1 on 5.3 heads doesn't take much milling, but the valves are .030" lower already so cam choice is important.
