351m\400

[eischee]

:wacko: What is the acceptable compression test per cylinder on this motor? I'm almost positive it is set up as the 351 so If it doesn't pass the test I'll rebuild it as a 400. Thanks for your help. Kregg

The compression may vary from 100-160psi for an individual cylinder. More important is the variance between cylinders should not be more than 75% FROM LOWEST TO HIGHEST.
