Well, here it goes. A 390 block, with a 427 crank, correct size H-beam rods, to 12:1 pistons. 427 Tunnel Port heads/intake, ported out. A solid flat tappet cam, about .600 lift with 1.7 roller rockers. I would probly try to adapt some fuel injectors into the manifold, with the holley throttle body. Some hooker super comp ceramic coated headers would have to go on there. I would get the whole bottom end of the motor balanced, just for good measure. How well do you guys think that motor would work?
