I’m positive I had them plugged in. My wire harness for coils probably got damaged when I removed them from the bracket and painted the bracket. Wires were hard as a rock and didn’t want to bend or move. I’ll try a different set this time around.

My cam specs are 218/222 on a 110+3 .587/.578 nothing major.
LY6 rods and pistons.
NNBS intake manifold
8.1l injectors
ls3 throttle body
pac racing springs
trunnion rocker upgrade

milled heads .030
comp cam push rods
shorty headers

How much horsepower you think this motor will make?

2600-2800 stall converter
4l80e

Ah man that sucks but nothing on these trucks is really hard to work on especially if you have already messed with everything at least once.
