Well my 505 with OOTB 270's made 713 hp 707 torque with a 4150 950 cfm carb and a Dwayne Porter roller cam. Mopar 337 intake (no valley pan) - needed small adapters on the ends to make fit.
Not in the car yet but it will be street driven.
We had a pump gas 505 on the dyno recently that made almost exactly the same power. It has TF 270 heads with a port matched Indy 440-2 intake and a Holley Sniper. That engine had a Comp street roller cam in it and 2 inch dyno headers. Nice strong engine that is going into a 1969 RoadRunner. Should be a fierce combo on the street.
