Hi Brian,
I've been running a Howell TBI on my 74 CJ5 with 258 engine for 3 years. I bought it mainly to improve off-road performance and it has not disappointed me. It also improved highway performance significantly. There is a discussion forum for Howell TBI users. You should have a look there. Here's a link to it:
