I'm in the process of converting my 77 CJ from the stock 1bbl carb to MPFI. I got the intake manifold off today, and as I expected, the new intake does not mate with the old exhaust manifold, so I'm going to order a set of headers and start working on the rest of it next week. I'll post some pictures of the project as I go along.

Here's my Jeep:

It's a 77 CJ7 with a 258 inline six. Everything is basically original and it has 90,000 original miles.

This is the engine:

And here is the new intake manifold:

Parts:

Stock Mopar MPFI intake manifold, injectors and throttle body
Custom AFI harness and Chip
1227730 Batch Fire Speed Density ECM
Custom-built distributor with GM EFI module
New tank with 75 psi in-tank fuel pump

Engine Controls:
TPS
IAC
MAP Sensor
Heated O2 Sensor
ECT Sensor

I am estimating approximately 150hp after the upgrade, which is a big improvement over the stock 90hp with a 1bbl carb. Looking forward to hitting the trails 4th of July Weekend!
