A little bit won't hurt but,,,, if it is way over full your crankshaft will
have to fight it's way through the oil so your mileage and power will
suffer. I lost a fuelpump diaphram on a 327 once and filled the crankcase
with gas. Had one hell of a leak, out the dipstick, oil filler cap, blew pcv
out. Sure smoked a lot too.
