Just have to mimic what Pontiac did on the '69 428HO GP & '65-69 B series with 421 HO & 428 HO engines.. Will need long branch HO manifolds & the special oil filter adaptor. Dport long branch manifolds have been reproduced for many years, both by Classics of OH, sold to many retailers, & RARE's own castings.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
