I've bought a boosted 01 cobra engine with 04 cobra pistons and rods in it but the crankshaft is still the 01 crank, my question is does the 01 Cobra crank changes the compression ratio to 9.85:1 or not? Because I've got a bigger build for the engine and I won't risk running this high compression on my project, should I leave the crank or replace it with 04 cobra crank? Because I want the 04 cobra compression 8.5:1
