New LS for my 72 blazer

[C.I.Blazer]

Sub'ing onto this thread as I am doing a swap into a 4x4 as well. Spoke with Tilden yesterday and am sold on their product (plus reading Blazerowner's experience and others). They did say that I may have to move everything forward an inch to get the motor to clear the firewall. Some do, some don't.

I am putting in the 4L65E that came with my 6.0. I spoke with Advanced Adapters and ordered their kit. I will take it to a local transmission shop to have the new output shaft put in. Anything else I should do while they have it opened up other than check it over?

Just got done rebuilding my NP205 with the ORD kit and am hoping to leave it in the stock location.

Starting to think ahead to the wiring part of the project. Blazerowner, are you still thinking about the Holley Terminator Max? Care to share your thoughts on going that route?
