Help with compression ratio calculatio
1. LS3 73cc heads 4.0 x 4.0
2. LS3 73cc heads 4.0 x 4.125 stroker
A friend has some mew Trick Flow 73cc that he wants $3300 fully assembled. I will add Pro Charger 10 to 20# and octane boost or water injection . This isn’tsn’t a daily driver.
i have not yet purchased the pistons nor the MLS gasket

The 4.125 stroke engine with the same parameters will be 10.75:1
I’m moving this to Internal Engine…
