Quick question. I could not search it ( under min. words..) Where are my RPM's going to be with 4:10 (in a 94 Z28 , 6 speed) at 80 mph? Thanks Guy. John

 

If I remember correctly, I am at about 2100 RPM

 

Thank you!!! I figured between 2000 and 2500 @ 80mph... I'm ok with the cam I am using then. Once again, Thank you for taking the time to responed. John
