Car ran slower then expected.

My combo is
360 .30 over
Speed pro flat tops
Mp .484 cam
Eddie heads
Performer rpm intake
Eddie 650 avs

727 with 3000 stall

8 1/4 3:55

Car turned a 13.6 and was missing at the big end. I'm going to bump the timing down and switch to a Holley but the combo should be in the 12s and I don't feel it in it!
