If you guys could build a "street killer" 393w stroker without worry of funds, what parts would you select? PLEASE LIST SPECIFICATIONS OF CAM. The block is a '69 351w bored .030 over. The engine will be placed in a '70 Mach1 with a Tremec TKO (5spd) tranny and 3.89 gears. I am looking for around 450 HP. Thanks.

stock 351w block, 8.4:1 compression, a pair of GT25 Garrett turbos feeding 10 psi. Cam would be a Lunati 510A4LUN which is a 226-210 @ .050" (intake-exhaust) with .525" lift on both. I'd guess it'd make around 580-600 conservative HP at just over 5000 RPM. Should be a complete torque monster all across the RPM band. Add a set of Vic Jr 70cc heads, or even 60cc ported, and I see no reason it wouldn't make 650-700 HP, yet idle smooth, quiet, and with no giveaway of what's under the hood. Those GT25 turbos are similar to the T3's from 5-speed TurboCoupes 87-88, but use ball bearings instead of hydrodynamic bearings. The exhaust A/R is .63 compressor is .60. Add in intercooler, and 750-800 HP is easily achieveable. That's when the stock block becomes a weak point.

Or...with what you already have, I'd use an Erson Hi-Flo 2M camshaft, which is around 232-232 @ .050", and a .542" lift. That would be about as big as I'd go with iron heads. BTW that is a mechanical flat-tappet cam. A 750-850 carb would be in order, as well as 1 3/4" or 1 7/8" long-tube headers to scavenge the hot gases.
