My 1965 B-Cuda had a HP 383 when I bought it in 1986. It was nose heavy and the steering shaft was into the left ex manifold and would lock the steering when torqued up. Could not afford "Stan's" headers so had to work with 383 logs.
Changing spark plugs was HARD, remove the left motor mount and jack the engine up. Right side was a little better. Had to use a MODIFIED 13/16's box end wrench on most plugs.
Small engine compartment meant no air flow out so even using a bigger radiator, DC P part 5 blade clutch fan, Water Wetter, and every trick at the time it over heated.
It was fast in a straight line but had to slow way down to corner.
