Just got done installing the 66's and the power gains are crazy! I was really over jetted!! I thought they where 72's, nope 74's!
BUT, I must have a internal leak somewhere! I can still tighten down one side and the car will idle! I'm going to look at the drawing on the Holley site -
Any other IDEAS?
thanks!
