I would buy a new 4.0 short block. Thats the deal right now. Redo the heads, throw in a new cam if necessary and put it back together. 1200 to your door for the short block. Don't mess with used or rebuilt when a new short block is so inexpensive. Ron | ||

Short block: $1200 Gasket set: $175 Bolts: $100 Heads: $0-1000 Cam, lifters, pushrods, rockers: $0-1000 Depending on the level of maintaince the cam is likely fine on a 4.0, a new cam can be had for ~$300, but new lifters are $$$, as are pushrods, rockers are cheap though. Heads are the same thing, you can DIY a valve job for nothing provided you check the heads for warpage with a mechanics straitedge, or you can go whole hog with new nitrile valves ($400), machining of the heads and three angle valve grind ($500), new guides (maybe bronze $100). So $1500 in parts at the minimum but depending on how far you want to go 3500 or more is not out of the question. Ron | ||

Why not just drop in a 4.6? |
