A-Bodies...Big Motors / New Hemi Duster - FINAL ASSEMBLY
our #'s are flawed...
what cam is in that 383?...500 lift, aint no stocker...and look at the intake and 1" carb spacer...does it look like a coffee getter set-up?...no, it is a mild race motor with 10 plus to 1 compression.
like comparing apples to oranges
if he wants a more power....bigger cam, then bigger carb, and maybe 3:91's.....of course, then you loose drive-ability, ...... you know, the reason he built it.
