That piston isn't 50 over. It says 0.50, indicating .5 millimeter. Unless it is a 1/2 inch over piston for the 7M. I don't think he recongiized that. ;)
.5 is 1/2 mm over. That is about 20 thousandths. That would be a standard overbore.
Last time I checked JE sold rings seperate from pistons. I can't believe you can't find any. Maybe you just meant you can't find them at .050".
Are you going to blast him with your M4?
Nice car other wise. Looks good.
My car was rear ended for about $3800. The insurance company also "totaled it", and wrote me a check for $5800.
After reading the various valve spring threads on various forums, I would do the BBC inner. Seems too easy.
If you plan on spinning this engine high, yes, you should upgrade everything in the valve train.
