Don't forget to make your calculations through the left end of the spectrum.

The only way that will be successful is if you can use a 8.1 rod along with the 4.625 piston. May also have to be a negative stroke. However, no relieving will have to be done for the valve/cylinder wall shrouding.

Can you figure out how to put a 4.625 piston in a stock 350 block?

This is a stupid question to waste your time.

Please make 20 pages of posts arguing about it.
Why dont you just machine the piston down to 4" ??

Apparently it is time for the skirtless, single pin tower forged piston, to reduce friction and weight:
