V-8 Into a 6-Cylinder Compartment

Q: V-8 Into a 6-Cylinder Compartment

I have a 400 block built and plan on putting it in the 1967 326. I was wondering what special bracketry I mich need to accomplish this.

A: If you use all of the bracketry from the 326 motor, you don’t need anything extra. About the only possible hang up is if your block is a 75 or older. After 1970, all Pontiac V8s were cast with 5 holes on each side to allow installation in either early or late chassis. Some 75 and later engines either don’t have all of the necesary holes tapped, or they aren’t present at all. New motor mounts are usually a good thing since after 33 years, the originals are a bit tired. In general, 326, 389, 400, 428, and 455 all interchange.

Other than that, this should be a simple bolt in. Just don’t try to interchange your 1967 accessories or brackets with any later stuff. You will risk pulley alignment problems.
