Technical Help going from 5.3 lM7 To 5.3 L33
This is my first time planning an engine build and I really try to do as much research myself as I can before resorting to asking questions.
Overall question & TLDR: can I run my 5.3 L33 Aluminum Block (Flat top pistons) // Milled .030 243 Heads, 225/229 Cam // 7.40 pushrods with either 0.051 or 0.040 compressed thickness head gasket or will I run into clearance issues? What kind of new clearances do i need to be aware of or should i order an adjustable push rod and get to measuring?
Previous running build was a stock 5.3 LM7 Iron with the same head, cam and push rod combination and a 0.040 headgasket. Compression calculator shows 9.71.1 (assuming deck clearance is .006 which was the reference i came across the most often)
Today I picked up an L33 with flat top pistons and based on the compression calculator if i moved over my 243 heads (milled 0.30) I should be between 10.73.1 (with .040 headgasket) and 10.45.1 (with 0.51 headgasket.
I run the Michigan Motor sports Stage 2 drift cam package so that's where I get my cam info and pushrod sizing from.
