You are already changing the shortblock, change too many variables and you might waste a lot of time chasing your tail in circles, dialing it back in.


BTW, your current combo is HEAVILY influencing what I'm planning on doing with my '73 ;-)

I'm around 700 rpm under the shiftpoint at the traps.Its not ideal for the qtr mile but it sure works on the highway.My car sounds different than a lot of cars I'm sure from the 1/8th mile where I basically go into topgear and to the finish.Instead of winding out back up to the shiftpoint and beyond my car just uses the torque it has and lumbers down the track.

On track days I like picking out 2 different types of cars to run..either newer cars that are quick or cars that launch hard with shorter gears,more stall,louder and more dragstrip oriented.Its fun running down the shortgear cars when they start to run out of gear.
