please help with my combo

ok so me and my friend are building him a little s-10 project so he can have some fun before he moves back to the uk.

so here are the specs

1970 gm 350 2 bolt main complete rotating assembly ballanced for 8500 rpm

edelbrock performer RPM aluminum heads 64cc w/ 2.02/1.60 valves
guide plates and screw in studs

crane energizer aluminum roller rockers 1.5

edelbrock torker single plane intake

speed pro short skirt hyperuetic(?spelling?) pistons rated at 10.74 w/ a 64cc combustion chamber

bored 0.030 over

chevy pink rods shot peened and re-sized

stock crank turned 0.010

comp 3/8 hardened pushrods

comp cam dur. 259/266 lift 550/570

edelbrock 750cfm carb

proform distributor

msd 8.5 wires

edelbrock aluminum water pump

serpintine belts

and short tube headers with open exhaust

this is all going into an s-10 that should weigh around 2800 lbs and will be running a 10.5 slick with a built th350 that includes race clutches trans go shift kit and all the other goodies as well as a tcs 2800 rpm stall tourque converter it will have 4.11 posi rear and im jsut wondering what this motor should be revved until and also what the horsepower should roughly be as well as 1/4 mile time?? we roughly based the engine off of the edelbrock 420 hp 355 so im hoping this will make at least that maybe more because of the bigger cam and more compresion- thx alot

If you plan to rev it past 7 grand, You`ll need a 4 bolt block, and better rods than the pink jobs. you mentioned "stock" crank, if it`s a cast iron crank I wouldn`t use it for revs past 6500, you`ll need a forged unit. For the cam you have picked I`m assuming it`s a roller cam, you`ll need a stall bigger than 2800. I would also run a forged piston, the hypers aren`t meant for revvers. if you plan to run the combo you have go with a smaller cam that has a more realistic RPM band that matches your combo.

is that an @.050 duration on the cam?

If so its way too much, those heads intake ports are like 170cc.

Your stock bottom end will grenade long before you ever get to 8500 RPM... or 6500RPM for that matter.

Other than that it looks strong-
