I run at 42-4400rpm down the track if I keep it in 2nd gear. 3rd gear it is around 4k depending on the track. I have an auto trans, 4:10's, and a non wastgated K31 from II. this is in low range with 33's. the pump has a 5k spring kit in it, and I do see as high as 4700rpm it I dont shift it soon enough. I also have a 2300 stall in the converter which helps. pump is a 12mm from II with 18* timing
Does the motor pull to much over 4700rpm or was that just a one time oops kinda thing?
