Few pics of a friends 4.0L build for his YJ. R&I (remove and install for you non-techs) is being done by Down East Offroad, and machine and head work is being performed by H&F Performance. I've used both companies for many repairs, and in my opinion, are some of/if not the best in their fields of expertise! They are both located in Wilson NC.
He opted out of a stroker build, but the block is bored 30 over with oversized pistons. Custom headwork is completed with a port match and polish along with roller rockers and matched camshaft. All of the stock electronics, sensors, and modules will be retained for relibility. Never know when you might need to borrow a friends extra crankshaft position sensor to get your junk cranked on the trail! Nothing worse than needing to borrow an apple...and all your friends have oranges!
I'm just glad to see another 4.0 saved. Too often these things are replaced with whatever 350/351 v8 that happens to be rusting nearby. Don't get me wrong, I love a small block as much as anyone, but the name of this game is functionality and reliabiltiy.
