1933 stock v8 40 compression test results & advice welcome

[drolston]

A stock engine with those numbers will run just fine. It is good that the numbers are all fairly consistent.


When doing a compression test it is best to do it on a warm engine. Be sure all plugs are out so you get maximum crank speed. Have a fully charged battery. Block the throttle and choke open so there is no restriction on the intake side.
