Mike If you do alot of starting and stopping with a motor that needs 1,000 rpm to idle, you may want to look a trans change or rearend gear change to low speed driving. If you keep slipping the clutch to get the car moving, you are going to keep going through clutches. Do you know what the ratio is in the trans for 1st gear? You may need to look at something in the 3.15-3.25 range. Get a wide range trans with over drive. This way you can crawl along at a low speed and have the motor not lugging and hicupping trying to run. It will also make it easier to engage and disengage from 1st gear. This will cut the slipping down. I have a 3.15 in a race trans and never use it. My street trans has a 3.25 first with overdrive and again don't use it at the track. When I need to putz along a 1-3 mph this works great. Parade speed.
The other idea is to put a smaller camshaft in the motor to move the power band lower and increase the torque band off idle. You will still have almost the same power, just at a lower range. Talk to Ernie, (Excaliper) aout his motor change or look at the old threads on his motor build. Hie gas mpg doubled, drivability improve big time, power was still there, and the car was only .5 slower in a 1/4 run.
