Next step is installing the cams, then back to the dyno, then the heads/cam combo. Lots of work but very anxious to see the results and Vince will be tuning for each.


Here's a little bit clearer example from my Camaro... Just for grins we did back to back pulss until we peaked... The Camaro made the most power on the 5TH PULL!!
