Just wondering if any of these bad boys were factory installed in ANY Oshawa built cars......especially Pontiacs?....or was that one even available....
I was thinking to myself "How'd they ever get 425 horsepower out of one with those horrible exhaust manifolds", and I think the answer is they didn't - they dyno'd them with no accessories, cold air, and open headers in those days (pre-72). Probably under 300hp net!
