The Pontiac 428 was introduced at the same time as the Pontiac 400 V8 in 1967 and used primarily in the Grand Prix, but also for the legendary GTO and Firebird models.. Although the 428 was modeled after the Pontiac 421, it had a cast iron crankshaft rather than the steel used in the 421.The 428 was one of the long journal V8 engines that Pontiac produced The most probable head swap is a 1967-up 4 bbl head for a pre-1967 or late 2- bbl one. In either case, the change in valve diameter is 2. 11 for 1.92 or 1.96 . The corresponding increase in valve lift area for the former is 10% if the cam and rocker arms are unchanged. The rpm must be increased by a like amount to maintain the same gas speed It was the first in a long line of high performance Pontiac heads with screw-in studs and stamped steel pushrod guide plates. If one obtains these 670 heads, and opens the chambers ala the 1968 and later 400-428 heads, and adds the good valve prings, you will have as good a high compression head as is possible to find

One in the Midwest - Royal Pontiac (home of the Bobcat Kit), and the other on the East coast - Myrtl Motors. Myrtl built 428 Firebirds and GTOs, they sold Tiger supertune kits, traction kits, suspension goodies and anything else in the way of speed equipment to make Pontiacs haul tail The more muscular looks weren't just for show either, as the 1969 Grand Prix retained the 428 V8 found in the '67 and '68 models. But, in 1970, things got even more powerful.
