Looking for estimates as to what my cranking compression test readings should be. Calculated SCR is 10.01:1. Engine is small block 383. Cam is hydraulic roller .530/.545 lift, duration @.050 is 233/241 lobe separation is 110 degrees. 1.5 rocker arms. Performer RPM intake, 195 runner ATK heads with 2.02 intake valve. Quadrajet held wide open while cranking, engine warm. Considering the cam timing, intake and heads, I'm thinking there is not a great deal of intake velocity at cranking speed, especially with gear reduction starter. Closest guess wins the prize. Thanks guys. Brent.
