432 Remember that blown gasket? The next weekend I managed one race. The reason? This Holley manifold! It's Mexican! See the recess for the distributor? I never noticed at the time of installation but there should be no recess, only a flat machined surface. When the distributor was installed, it went into the hole and was canted to the side because the hole wasn't centered. (mexican) That DESTROYED the cam gear of the distributor and THE CAM! The engine cut clean on the return road and I went home. Good thing for the trailer winch! Grrr,,,,
