I can't do wiring either. I would have to have a shop do it. And shops cost too much for me unless its in a buddys shop done together in an evening or weekend. My 442 509 Caddy swap was carbed so no wiring issues. It also used the factory 200-4R so all I had to do was heat & beat a little room for duals on the crossmember while it was up on the lift. Sounds crude but it only took 20 minutes and with a little spray paint looked shockingly good. An LT1 & 4l60E would be too much work & expense for the reward for me. I gots to keep it fairly simple & cheap.
