408 Stroker Build Suggestions

I run a smaller comp 274-S solid flat tappet cam and 9.7:1 compression, edelbrock “63cc” heads, scat kit: cast crank/I-beam/17cc Icon/balanced, M-1 single plane, 750+ cfm BG Silver Claw dbl,

Since you are looking for something real street freely I would limit yourself to 91 octane pump gas with 9.5-9.7:1 compression, flat tappet cam.

The heads and piston give me quench to help fight off detonation. If you need reduce compression, run the stock Fel Pro gasket that thicker. I run the thinner performance line gasket.

I think .500 NET lift is max for stock rockers. But stock rockers are 1.46:1 ratio. So you can get away with .515 or so advertised lift with flat tappet hydraulic cam

Add a edelbrock rpm intake, 750 dbl pump, TTI or Dougs headers... and you have 425-450 hp motor built economically that will fry street tires at will. Probably more.

I run ported heads, solid cam, comp roller rockers, bigger cam and single plane looking for a little higher power curves for when I occasionally go to the track and not dip below 3K rpm.
