Okay I have '69 351W that I bought already rebuilt so I don't know the specs on it.

I cracked a piston so I am planning to replace them with forged or hypereutectic. What do you guys suggest? I also want to bump up the compression a bit and replace the dished pistons that were in it. I know the 69-70 have a lower deck height causing clearance issues with some pistons. What are my options? Also, I assume I should go with ARP rod bolts when I do this....any thoughts? I am running factory heads and I may do a little porting to them before they go back on....

Also, stock size bore size is 4 inch , but what is the actual piston size, there has to be tolerances. I measured the piston last night and I think it was around 4.020 or so. Is this typically marked on the piston somewhere? I just need to reorder the same size. I assume its .030 over but it may be less...

A 4.030 bore would have a piston of what size?

Thanks,
Ryan
