505 rb build advice needed for 39 dodge

That will be one fun 15 mile ride to work. You better have it pointed in the direction you want to go when you pull the trigger.

Power and torque? We built a 496 with the 4.15 stroke, mildly ported Edelbrock RPM heads that flowed 305 cfm @ .600" lift, the Lunati 60333 solid roller, Torker II intake, 1000 cfm 4150 and it made 642 TQ @ 4600 rpm and 642 HP @ 5800 rpm. Right now you have a little less head flow, a longer arm and a little different cam. Probably close to the same torque and a little less horsepower. I'm guessing over 600 lb-ft of torque from 3500-5300 rpm. The tunnel ram could get enough air to the heads to pull the torque a little higher in the rpm. But of course I'm guessing, I no expert as others here are.

Laurel, right close to Billings. How IS that drag strip there? I hear it is nice.
