Crank Bolt Size
Hi everyone.
Can anyone tell me what size the crank bolt is on a 70 Olds 350? I have a car that's been sitting a couple years and now the engine is stuck. Yes it ran fine when I parked it. Won't move with the starter, won't move tugging on the belts. I'd like to put a breaker bar on it and see if I can't muscle it over. I can't see the bolt and can't feel it since I can't get my hand past the fan. Also I thought I'd squirt something into the spark plug holes. What's a good serum to use? PB Blaster, Kroil, everyone's favorite WD40?
Thanks everyone.

You will need a 1 1/8" socket and a HUGE breaker bar.
