Help you out Bill.
STOCK Pontiac Distributor Gear Diameter is 1.350 inches
Stock Pontiac camshaft gear is 1.985 inches. .635 inches in diameter difference but same 14 tooth count.
If Pontiac Bored the hole Bigger on the Block and made it .150 inches larger then the new distributor gear
size would be 1.500 inches and the camshaft gear would be 1.835 inches so THE DIAMETERS OF THE TWO
TEETHED PARTS WOULD BE CLOSER TO THE SAME DIAMETER. These are general dimensions and there is
always a bit of room to get the gear inside the block.
So now the tooth spacing (for the 14 teeth gears) would also be closer to the same.
