It is almost identical to the 440 in my 63. I have a complete stock bottom end with KB quench pistons for my 906 heads so it runs great on pump gas. I have 10.0 comp and I installed the 2.14 and 1.81 valves in my 906's also. It has Hedman 1-3/4 headers with 3" exh. I also use the Holley Street Dominator with an 850 DP and I use the MP .557 cam with Isky nodular iron rockers. I use 4.30's with a 30 x 9 tire and a dynamic 9.5 converter. My 63 weighs 3700 with me and I figure it is making right about 500 flywheel hp by its 11.49 @ 116 best et. You should go easy 12's in a B-body and maybe even low 12's with the right tune and drivetrain combo. Ron
