340 to 416 stroker build need advice

Agree with Moper, but my 2 cents, if you go half way big o nthe cam, get 10:1 - 11:1 pistons and after bore sizes, milling etc you can ru non pump gast with iron heads. We need more info, but it is the effective compression that is what matters. With head work and not to much cam, depending on deck height etc. 9.5 may be ok for you.

I went with Ross Forged pistons and a forged crank. Very sweet on the balance and I wanted mine a little more bullet proof.

PS I do not have power brakes.. way to much cam in mine for that.

Also what gears, trans etc are you going with and what is the goal, besides just more power?

PS a few oil mods would not hurt either...
