1989,
18% of 20 is 3.6 (mpg). Good luck dropping in a used 4.0L and getting that
Definitely contact Angie on those PARTS!!!
I only know a little about the 2.8l. There are 2 piston heights, the higher compression height is for the old Pinto engines.
• They should be worth 1 point of compression
• multi-angle valve job
• Milling the heads 0.035" will get you another point of compression .
• a complete bottom end balance will improve the overall efficientcy +10% (hp/tq).
• lose the crank shaft driven fan/clutch for an electronic fan
• custom reground cam (I would expect a solid +10hp, probably closer to 20)
• headers and free flow exhaust +10 solid (Svenn says more)
If you commit to rebuild, then pistons and rings are in. There were a ton of aftermarket headers for the old Ford v6's, so used SHOULDN'T break the bank; I remember Edlebrock had the TES (tubular exhaust system) in every old truck magazine.
A sourced, home build exhaust can be done very well for under $200, even in stainless. Fan kits are much easier to come by these days for <$100
**Summary**
Balanced bottom end (+10%), head mill (+4%), higher compression pistons(+4%), custom cam (+15hp), headers and exhaust (+15hp)...and losing that fan frees up a serious LOAD add an engine oil cooler. Your power, torque and fuel economy will see the approximate 18% efficientcy improvement plus, on paper anyway the 30+hp/tq bump.
With any rebuild, I can't help but suggest a new timing set, oil pump and water pump.
