Anyone know where's the best place to go to find a single stock 502EFI piston ? I've searched a little in classifieds but classifieds here are huge. Just thought I'd ask if anyone had a tip on finding just one.

Any help would be appreciated.

Ive got a full set out of a gen6 502mag EFI if youre interested. They are standard bore of course with about 250 hours on them. Make an offer! Would prefer to sell the whole set.

Unfortunately I posted incorrect info in that I posted looking for stock 502EFI piston. After tear down I found that they are .030 over. That is an available size. I've been offered a 30 over piston from HP500EFI. Anyone know if that's the same piston ?

well seeing how yours has been bored who know what pistons you have ?? so better be looking for #'s on the underside before you go looking for what you don't know you have...

Sorry the .030's are in the boat now. Good luck!

I have 6 of them.. Less then 30 hrs on them.

ELIMINATOR, are your pistons .030 over stock

Stock 502 are 4.470, I have 4.500 which are .030 over. These are the SRP replacement pistons for the Merc 502 (.030 over, now 509)PM me if you are interested in them.
