Do not get the FMS Block, it doesnt come with forged pistons... try Coast High Performand or DDS alot better components... CHP has a good 347 stroker kit that puts the pin below the rings..... good luck
how much horse do you think i would be putting out to the wheels with that set up an the custom cam? also would this set up and the custom cam be good with my gears? or does it not even really matter what gears you have unless you have a power adder?
I can see you hitting 375rwhp w/o a problem and untouched TW heads. You'll need to change the springs though. If I were you, i'd bump the limiter to 6500rpm and you'll make more power. Just be 100% honest to the cam grinder in what you want and they'll do what they can. Custom cams arent magic. You could possibly see 400, depending how wild the cam is. The tq should be excellent! Also, do NOT waste your money on a forged steel crank, buy a cast crank. Forged cranks in stock blocks are a waste AND their heavier.
