I had similar setup years ago in a 34 roadster. We cut about 1 inch out of the upper plenum, this brought some driveability to it. Still even a light car the bottom end was weak. It was bad *** though and drew looks everywhere we went!

Will work find for your purpose. Carbs and timng curve will need rework to dial it in.
Compression is very low for the cam.

A 350 with flat-tops and 64cc heads will be about 10.2:1 SCR. Cam and SCR are well-matched in your combination. Use 18 degrees ignition lead at the crank and 18 in the weights, all in by 2800. Edelbrock RPM intake #7101 with 750 carb, (double pumper if stick trans or auto with 3000+ converter, vacuum secondaries if auto with tight converter) 14"x4" air filter assembly, 1 5/8" long tube headers with X or H tube before the mufflers. COMBINATION, COMBINATION, COMBINATION.

Trash the 450 Holley. The instant you smash the gas peddle. Your car is going into a nose dive, Backfire or stall out. Not to mention pig rich at idle.
