Arrow Building a LS 408 Stroker Motor

Im building a 408 Ls stroker motor with 8 pound ProCharger Turbo 350 Transmission with 3500 stall and Ported Cathedral Heads, 4:10 Gears
Would like to run 93 Octane gas so I can drive it on the street? I need help on what and whose Cam size I should use and what compression Ratio I should go with?

Honestly i would call up a vendor when your ready to order a cam i have had 3 different cams from 3 different vendors for different builds and they was all great and as far as compression around 10:1 would be pretty healthy.

I wouldn't build a 408 either, too much stroke.

Dont necessarily need the stroke, 4.1 gears will be bloody short...and you've given no power goals, nor even which blower you want to use. Nor any details of the engine itself, or fuel you intend to use..

Give details.
