V8 is 33or34 thanks to your help. I was surprised how easy the spark plugs can out . One side had champion c7 the other c4s . What is the best size to use . Motor turns over with a socket wrench. I was really surprised. Where is a good supplier that I can get spark plug wires,distributor caps( mine missing) coil(the round style) ect. Also what would be a good manual to have . Thanks for your help. Miff

Is your car original or does it have a newer engine? You should post a few pictures.

If one cylinder head had C-4 plugs and the other C-7 plugs, then they have different thread sizes and therefore are different heads in terms of combustion chamber design and compression ratio, which is not a desirable condition. The head with the C-4 plug is a '32 head and the other one is somewhere in the '33-'36 era depending on its configuration.
