Parts required to swap from small block to 385 in a Superformance

[520SC]

You may need to swap your existing alternator bracket to a 385-series bracket.

Also, the small block coolant surge tank won't work on a 385. On a small block, the water exits the intake manifold horizontally. On a 385, the water exits the intake manifold vertically. You'll either have to fashion a custom 90 degree elbow, or come up with another way to vent the air out of the radiator. My car uses a 1970s Corvette surge tank.

On my Street Beasts 427S/C with a 385-series engine, I have an Edelbrock RPM Air Gap intake, a Holley 750, and a Spectre 14" x 3" air cleaner. It all fits under the hood with no modifications necessary.
