'69 Road Runner, freshly rebuild 383 with small Summit camshaft and 9.0 compression, electronic ignition with original heads and an Edlebrock 650. 4 speed with new Brewster's clutch and a suregrip 3.23.

When I start from a stop it seems like I have to ride the clutch to get the car to start moving, like is has no power. Once the car is moving and the clutch is all the way out it will accelerate fine and seems to have the power it should. The clutch isn't slipping, it just seems like I have no power/torque when I start letting out the clutch.

This is my only 4 speed car so I don't have much to compare it to but this can't be right. What are your thoughts???
