installed iron gt40 heads,ported stock lower and 1.7 rockers. still on the 125 wet shot and drag radials. shifting at 5200rpms witch may be too low.

1.43 60ft
7.07@95mph
11.23@117mph

i need to get it tuned and install the 150 jets and try for a 10.99
 
yeah on motor it seemed a little slugish down low. could be from the low timing or cold plugs or just the lower compression from the gt40 heads.

in the same weather before it was trapping 101mph n/a so it picked up about 3mph n/a and 5mph on the juice
