500hp from a “warmed over” 383 ain’t gonna happen.

383’s that make the type of HP are fairly high strung........ and need the necessary support pieces(converter and gears) to have good performance in the vehicle.

Put a 4.25” crank in it...... then you’ll be closer to the 500hp goal with the “warmed over” type of build.
