Finally did 2 test runs yesterday. Car did not pull in the last 1/8 mile of the run like the old cam I was using.

I have 1.65 Scorpion rockers, but with spring pressure applied they are 1.62 ratio. So the 60919 has .507 lift and the old cam had .532 lift with different duration-246/252 flat solid cam.

I realize the 60919 is a mismatch for my engine, but I had the cam so I thought I would use it.

1965 GTO 3800 lbs car and driver
t-400, 3.73 gears, 28 inch tires
428 .030 over , 9.7 compression
9380 Holley, 850 annular
RPM intake
670 heads, ported
1 5/8 headers, full exhaust

1st run 2nd run
1.693 1.689
7.781 7.769
87.35 mph 87.95 mph
12.335 12.289
107.40 mph 108.20 mph

With the old cam, those 60 foots would give high 11's for 1/4 mile times at 113 mph. I was thinking the 60919 would be at most 12.20.

Since we were rained out, I did not get a chance to tune/change anything.

Anyone have similar numbers for the 60919 or think something might be off, say carburetor, etc?
