Scat rods, no SIR's
No issue with a scat 9000 cast crank.
Look at Brians RHS X heads. They have made 500hp on 400+" engines. Once you buy valve train and have the speedmasters ported, you'll be in the same price range is my guess.
Simple cam, Voodoo hydraulic 404-405 comparable. Use a set of stock 273 style rockers.
The rest that you have will get you close to the 500hp range.
I agree my 360/408 Scat Cast Crank Scat Forged I-Beams and Icon Flat tops made 470 HP at the crank with worked over J-Heads....is still running strong today in a buddies car....he loves it and beats it to death in his Demon...lol
