Crane 2031 cam Questions ???

[Rick 91GT]

The 2031 makes a good blower cam due to the slpit valve lift and duration it will good NA though. Most NA cams feature a lot of overlap, the 2031 intake valve closes at -1 and the exhaust valve opens at 6 I think. The only problem some people have is idle issues, my dads 93 Cobra had a real hard time finding a idle now it's not a issue because he runs a SpeedBrain, but I run a much more radical cam and my stock 91 computer takes it pretty well?
