actually all pontiac V8s were 90 degree Vs. You may be thinking of chevrolet engines as most of them were 65 degree small blocks some of their larger displacement engines were close to being a big block. Even the GM 3.8 V6 is a 90 degree that explains why pontiacs were know for having so much torque because they were over-square most of the displacement came from stroke. If you look at the 350 in my 69 firebird, the 400 in my dad's 67 firebird, and the 455 in his 74 GTO you can see that the cyliders make a perfect 90 degree V.
