Where to start?

-----I recently had two 383 boat motors built for one of my Donzis. 416hp and 466 torque. I named them the twins . Remember, these are boat motors meant to run at about 5000RPM and provide as much torque as possible in a broad range. I didnt care about the horsepower that much. Just 9to1 compression with mid 90s GM aluminum heads, cheap GM alum manifolds, 750cfm Holleys, and fairly mild roller cams. You dont need a tremendous amount of high-tech stuff, just the right stuff! A well built 383 will give you the most bang for your buck!!! ......Bill S
