408 stroker engine build

I would expect with all the limitations you have that power would be low (375'ish) depending on the cam.
TQ should be great though.
I would use comp's new thumpr cam, works very well and it sounds nasty.
Carb I would use would be a 750DP Holley.
I'm a Scat dealer so that is what I use. 9000 series crank, I beam rods and KB IC745 piston.

You can get (millidon) 4 bolt main caps for strength. or ARP studs to keep it a 2 bolt. They never made a 360 4 bolt. Scat would be my choice. I am building a roller block 408,procharger, and methane injection. You will need to make the bottom end bulletproof to sustain 850 horse.:banghead:
