440 tunnel ram

Rechecked timing piston 1 at t.d.c

Both marks are at 12oclock then removed dizzy cap and the rotor arm is pointing to lead no.1 so i beleive the cam is timed correct. Is the easy was to get compression ratio up to install flat top pistons??


That just means the dots line up. If you don't put a degree wheel on it, you have no idea what the cam timing is.
