I think that 19 inch wheels would let it run faster. My 31 tudor with a completely stock professional rebuilt engine with side bowl zenith carb will run 65 mph. My old 31 coupe would run 65 mph with a stock overhauled by me engine with a Tillotson model X carburetor. Both of these cars have 19 inch wheels and are both 3.78 gear ratio with stock 4.22 compression heads. With 19 inch wheels and your snyder head, I think you will pick up a few mor mph. If 5.50 x 19 tires were used on the rear it would probably change the final drive to somewhere near 3.54 and would gain a few more mph and have an rpm lowering effect.
