Formula to shave pistons to reduce compression ??

[6pak]

284* intake cam with bring effective or dynamic compression down to the 9s.

You could chuck ‘em in a lathe and cut a dish in them.
I dunno. Just a thought.

Dynamic in the 9s won't run on pump gas.

This discussion is all theoretical now. The o.p. has decided not to purchase the engine he wanted to shave the pistons in.

You'll find it's a recurring theme with all his posts.

The piston shaving idea was for a motor I was thinking about buying. However, due to my having to buy 4 instead of just the one that is broken.They’re discontinued I am going in a different direction. I’m looking at a kit on eBay that is supposed to have Mahle pistons
That will produce 11.7 cr with a 65 cc head. My new plan is to use an .80 thousandths head gasket and take enough off the pistons to get 10.0 cr , very 93 pump gas friendly.

Like a MOAB, that'd be the Mother of All Head Gaskets.

Heck, you'd need longer head bolts or Studs.
