408
Don't worry about low end torque with a 408. You are choking the hell out of that big motor! You need your heads ported by a professional, Edelbrock Victor jr. port matched to the heads and a larger HR cam.
I have a 408 in my car with an Edelbrock Victor jr., Canfield
stage II heads and a HR Crane cam with 244in 256ex duration at 0.050 Lift. The car is a torque monster! I can spin the tires in third gear @60-70MPH with a T-5, just by nailing the throttle. I definitely have plenty of torque; my cars best sixty foot to date is 1.315 on the motor!.....James
