I have all the necessary parts except for the pistons to build my procharger engine. Do you think a 4.625 stroke and 4.50 bore would be too much for a F3 build

Friend is running 622ci and revs it to 7.600 with an F3
Deck height is your friend, pack as much meat as you can on top of the pin.
Depending on how hard you want to get at it, I would personally keep the compression at or tad below 11 on methanol.
