Default 228r 60cc 5.3 heads ptv compression?
Just ordered some tsp 5.3s at 60cc. My calculations put me at 11.3 scr but I’m starting to wonder if this thing will bleed off enough dynamic for 93 with the 228r on a 112 and will it clear?

small cam, and Ive ran almost 12:1 on 93
people always seem to forget that ls2's are almost 11:1 from the factory
With anything though you need a good tune

Use the dynamic CR calculators that are out there. You will need the Intake Closing point to complete the calculation. You can always retard the cam to lower the dynamic CR.
