Cab, i built a 408 dodge stroker using EQ iron replacement heads. Bowl ported with 2.02 intakes. Made 504 hp at 5700 and 518 torque at 4600 rpm running a Comp Thumpr hyd roller with 235/249/107 specs. A milder cam might not make as much power but will still shine! The heads flowed 276 @ .600 lift. I used an rpm airgap and TTI step headers, 15/8 to 1 3/4. 10/1 compression. Sold it to a guy 5hat drove it home 308 miles.
