I have a 1994 z28 with a rebuilt 4l60e and a cc306 cam with Long tube headers, full 3" exhaust mild bolt ons 3.73 gears I might add nitrous later on not sure. I was thinking around 2800-3200 or should I go higher I am just not sure. Thanks for the help!

 

Forgot to add the car is driven maybe three times a month on the street other then that I take it to the strip.

 

I use a Yank SS3600 and it works pretty well on the bottle. It's also tight enough on the street that you hardly notice it's there. That's with 3.73 gears by the way.

 

I just bought a HUGHES performance 3200.

 

Go higher IF your main concern is dragstrip oerformance.
