Pushrods!!!! <img src="/forums/images/graemlins/confused.gif" alt="" /> all of this new stuff I bought and pushrods is what has got me stumped. I know that the rocker arms are the same between the 82 and the 95 head because I checked the PN's online, but what pushrods do I need to buy and how do I check to make sure there the right ones? I have 4 different books on my jeep (and its frankensteined parts) and I can't find anywhere that shows or tells on how to check which pushrods I need. The block is a 258 I don't know the year, and the head is out of a 95'

By the way, I got my shortblock 258 back from the shop this week and they bored it 30 over. I can't wait to throw this baby in with the 95 4.0 head, borla headers, and MPI. Now if I could just do something about that body rot <img src="/forums/images/graemlins/shiner.gif" alt="" />


1982/1992 CYJ "FrankenJeep" SOA with Waggy Springs 1" body, 4.0 head, borla headers & cat back, mopar MPI, Jacobs ignition, York air, Custom 3" intake w/k&n, K5 heater, Flexlight fan, 33" Coopers, DANA 44's, lockright up front, NP 435...In progress.

Everything I have read says they will all work. Although I have not finished mine yet. All the parts are in the garage but except head bolts and new exaust. I can't wait.

I know from rebuilding so many that there are several sizes of pushrods.. I have never installed THAT head on THAT engine.. I think I would go down the the parts house and ask for one of each and stand them up side by side and then I would KNOW what I had to deal with. When in doubt I always go a little longer. If too long the darn valve won't close.. If too short you will have an immediate click. If almost too short then the click will WEAR into hearing before it's time.
