Need Help on Magnum 360/380 hp Crate Motor Tech Info

The engine is a stock engine minus the cam, valve springs and intake. I don't remember pistons being special.

Being the cams intake duration is [email protected], that points to a approximate starting rpm of 2000. You should be looking at a stall converter of approximately 300-500rpm more as a min. You may want the move that up to 3000 because it is in a 318, 42 cubes down from where it came from.

A min. gear recommendation is 3.91's. 26 inch tire to go with it. As a min.

Your P/B are on the border line.
