Mystery B block intake....

That was on a 440. Can't assume the same results on a B series, similar yes. Besides, with a big block, even with a stock 4 barrel, you're gonna have plenty of torque to move you. The differences are mostly gonna be felt on the time slip

if you want a good street intake that allows room for growth, the Holley Street Dominator on a B series is pretty hard to beat. I had one on my 400, which later grew to 451 in my charger. Find one of them if you can would be my suggestion.
I made the ebay guy an offer on the intake.....I will keep the Domnator in reserve [in my mind]. I have an old '60's-'70's [?] Edelbrock Trantula TM6 on the motor now. When the rear gear gets changed from a 3.55 to a 4.11 I might be good to go with what I have...we'll see.
