My apologies to The OP, not trying to hi-lack . I acquired a P-4B secveral yerars before I happened to find my GTO. The GTO has a 428 with 6X-4 heads (stock) and a Performer (not RPM) intake. I am curous if keeping the Peformer would be better or worse than using the P-4B. Thoughts?
(I suffered a shoulder injury a while back and am able to deal with the aluminum intakes' weight but the iron intake would mess me up even though it would be better power wise.)
Thanks!
