Don't ask how it worked out this way but it did! A '42 flywheel from a 216 is mounted on a '55 full pressure 235, in a '54 chassis. As long as I don't stomp on it too much the 9 inch clutch doesn't get too blue! The problem is the timing mark is the usual pressed in steel ball, but I think the '42 216 flywheel had that ball pressed in at something different than what it was for the later '55 and 56 Stovebolt 235. 5, 6, 7, degrees BTDC?? If I knew that actual number I could dial it in on my handy Snap On timing advance timing light!
So now that I've had an overheating problem which appears to be timing related, what is the actual NUMBER of DEGREES in BTDC timing that the '55 motor should run on? Anyone, anyone...?
