Yes, indeed.. I'm not surprised... remember, the 400 was last built in 1978 (a few were used in 1979s, but they were made in '78). The last 455 was made in '76. That is almost 32 years ago. And they were never volume engines in the way a small block Chevy is. The "modern" Pontiac V-8 was only in production for about 20 years before it was retired.Originally Posted by mrblanche
The good news is that the aftermarket now offers some Pontiac blocks and head castings, in cast iron and aluminum... but they are expensive.
Before we moved, I sold off three incomplete engines I had laying around, including a very rare 1970 casting RA III 400...
