I have just purchased a used olds 442 400 engine. I assume the specs of the pistons are .030 as the top of the piston has that engraved in it. How do I find out the stock length of push rods for. the 66 olds 400 engine?

How will I know if the main bearings and rod bearings have up sized to a 010 020. 030 etc....

How can I tell if the cam is still good to use!

The reason I ask all these questions is that when I pulled the head all the valves and spring and seat etc. had been redone. The valves had never even seen fire and still had marker numbers on each valve.

Thankzi Koop I’m
