Its been a few years since I've done anything with it, and much of the work was done by a shop for the previous owner, but what I can recall offhand is:
Carter 400 CFM 4-bbl (I'd like to go up a bit more. Regardless of the math, I've always found that the 2.8 likes a bit more carb) on an Offy intake. Dual air inlets with fully functional heat riser valves on a stock air cleaner and K&N filter, MSD 6A with Duraspark distributor
aluminum timing gear, Custom-ground cam (I was told its a bit hotter than an "RV" cam), and I was told that the pistons are forged (never pulled a head or flipped it over to look) Mustang II flywheel/clutch/pressure plate
86 Aerostar shorty "headers" with true dual 2 1/4" stainless exhaust and glasspacks, connected to a Toyo/Kogyo 5-speed and 2.48:1 transfer case, into 4.10 trak/Lok and 32" tires when it was in the Bronco II. Sucker would stand on the rear bumper if I side-stepped the clutch at 3K in any of the first three gears in 2D low range
I was also running the stock A/C pump converted to an onboard air setup, which would run any of the usual air tools and a nice set of trumpets...
The guy I got the engine from originally ran it in his Pinto, with a RAD 4, the stock air filter, Duraspark box, stock exhaust, and 13" rims with 3.20's in the 8" diff. He twisted the front subframe over 8" with it
