Re: 401 vs 432 torque ratings???
Make sure you are comparing like figures. The 401 being older ws usually rated in gross figures, the 432 in net. The change happened around 1971. Net is usually 15-20% lower. Also, the 432 was tuned a little more for emissions, such as the standards were for heavy trucks in the early 70's. Nowhere near as stringent as passenger cars at the time, but still a factor. Yes, the 432 had Magnum heads, manifolds, and carb..
