MSD intake/5.3L
#19
Truck has MSD intake manifold, 1 7/8 headers (TSP) stock air box with homemade tube, exhaust and a 3600 converter with stock 3.42 gears. Day we dynod it rained so no 1/4 mile testing yet. 1/8 spinning went 8.39 at 82mph so I'm sure fine tuning at the track I'll see 8.20s or 8.15s but goal is 12.80s 12.70s bolt ons. Then 4:10s and aim for 12.40s
