I spent my weekend doing this:
Turns out, my 401 came back from the machine shop with leaky freeze plugs. So I had to get it out after going to all the trouble of getting it in my Cherokee.
I had a 360 rebuilt and waiting for my CJ project. So we put the 360 in the Cherokee so it would be running while I work on the CJ. The 401 will get the plugs fixed at the machine shop and then it will go into the CJ.
The good news is that the GM TBI conversion I did works reasonably well. I have to do some tuning but it runs adequately now.
I ended up blowing a transmission cooler line so I have to fix that. But that's minor.
I should have that 360 broken in by Christmas.
The 401 in that CJ should be a lot of fun.
