Dynamic compression ratio
Hi, whats the maximum static compression ratio using pump fuel advised to have in my 400 using this cam :
crane cam grind number HIT-282-2-NC, it says;
Intake@cam 3067 @valve531 Rocker Arm ratio
exaust@cam 3236 @valve 560 1.73
Cam timting opens closes Duration
@.0029 Intake 28 74 282
exhaust 80 30 290
hoy do you calculate dynamic compression ratio and what is the maximum dynamic cr to run pump gas ?
