ET'S with ported J/or other iron heads SB

Honestly, just telling the "one part" and leave the whole story out makes me sketchy. I say my combo from bumper to bumper. It is what it is. If someone likes it, great. IF not, ok. Truth be told, I could go down to Jabs house and build a low 11 second car within 24 hrs. He has 4.88's, stocker cam, 8" converter (4800 it think), and a 73 Duster with cage. All I would need to bring is the proper valve springs. His 750 DP would get it there. Just say'n, this isn't uncovering ancient secrets.

Come on down and lets get the Duster together.
Already have the valve springs and have a fresh tq carb from a stocker record holder.
Would like some differant rocker arms tho. Got the mechanical 273 stock rockers at the moment.
