Had An 89 Wrangler, Thing Was A Pain Until I Put A Jacobs Ign. And Howell Injecion In It. Ran Like Charm After That. Moved On Though And Sorry, No Pics.

I put the ProForm roller rockers on my 340 with no problems.
I installed them early this past spring. Did not have to adjust
all sommer long. I think they are worth it. I have a 484 lift
purple shaft cam though.
