i used Andrews 37g with cnc heads 1.9 & 1.6. 95cu. .030 squish. 9.8 comp e carb. DDT ignition tuner. had to fit a 30 tooth trans pulley to sit in 5th at 60mph. not the best cam

How would the cam impact gear/pulley ratio?

As we all know a cam has direct influence on where the Torque curve comes on. The speed limit is 60mph here so i did not want to ride in 4th on my 5 speed. Now that i went 107" with all the fruit i run a 33 pulley.

It may change the torque curve but it doesn't change what engine RPM equals what speed of travel in a given gear. If 60mph in 5th gear is at 2,500 RPM then it will be 2,500 RPM no matter what cam you have in the engine.
