Would a supercharger add more power, or cause other issues?

Hello all, I was asked what other modifications were done to this engine, here is the response;

Hi Len,

The compression ratio is 9 to 1 on an aluminum Laystall cylinder head. Bore size is plus 40 on a 1500 block. The distributer is stock with a Petronix inside. The Laystall head is not modified and the intake and exhaust manifolds are original and not modified. the test run was made with TF air filters installed. One and one half inch SU carburetors were used and Jim fine tuned the timing and carburetors during the dyno run. The crew made a number of runs before getting the engine to 90 HP at 5200 RPM with Jim making minor adjustments to the carburetors and timing.

Many thanks Bill & Jim,  Looks like we are all very happy with the results of the dyno tests!
What modifications were also done? What is the C/R ratio, bore size, was the distributor re curved, any porting, or polishing, or other cylinder head upgrades? Carburetor  needles? Dyno tuning to get to the results, etc?
Thanks again for your business
