Yeah I have the 6al, blaster 3 coil & MSD cap.
$420? That was installed right? If it wasn't you kinda got shafted.
I love mine. I have my 6al inside on the passenger's side floorboard. The coil is on the left of the engine.
Its a worthy investment that's for sure. Increase in MPG, smooth idle, and even cleaner shifts.
