which compression (not ratio) may I expect after engine modification (351c), approx ? 10 bar, 15 bar, 20 bar... at an expected ratio 9.5:1. thanks, Uli

i don't understand how these seemingly arbitrary bar figures relate with no knowledge of when the intake valve closes and the actual dynamic compression stroke begins?
256.x & 271.x psi are a good 100 psi over normal cranking cylinder psi findings
