Long duration cam in /6

well what cam are u gonna run, erson makes a 280/270 cam that i have heard is really nice!

but for startes ur looking at a 9.3-10:1 comp
oversized valves and lots of porting
high stall converter or bigger/better clutch
block work, bore and hone, line hone mains, oiling mods, decking of head/block.

before i get the head done i would figure out what pistons ur gonna run, if on a budget go to summit and get the .040/.060/.080 over pistons, i have part numbers for good rings on the .080.

get the bottom end loosely assembled before final hone! figure out ur piston to deck height measurement. then u can deck the block and figure ur compression. note: the more off the head the better combustion chamber shape.

is ur motor already bored??
