What size is your engine? Small block? Big block?

With my old setup I did a 13.335@105 with one of the lobes wiped and using 1.72/1.5 valves. The 60' was a 2.0? also. Oh yeah and I was running out of fuel on the top end.

My motor is just stock 350-Vortech heads 373 gear 3500 stall-to high! I run this motor in my 4dr cutlass-I had a 400 sbc alum heads last yr/ ran 8.3 spinning on whitewalls - 8.0's slicks! It has shocked a few newer cars at the track! Ugly cars are neat!
