My 418 small block runs well

In my 67 Plymouth it gets 1.34 60 ft.

It only runs 100 mph in the 1/8. This thing should be going 105 easily.

Thinkin when we put this Milodon gear drive on it we may have degreed the cam wrong. Going 4 retarded in stead of 4 advanced...or vice versa...hell I can't remember which way we went with it.

Based on these symptoms, could that be my problem??

It has a crank trigger...set at 32-33 degrees timing (this is where it ran its fastest) but yet will kick the starter back when trying to start it cold. Already snapped one new light weight starter in half.

This car pulls bumper draggin wheelies but doesn't have any balls at the finish line.
New converter and new E85 for this motor. Converter a new one from Lenny @ Ultimate ( I love it).

Help and thanks
