A Link For Those Interested In Building The 2.8

That link is one of the best 2.8 resources out there. The parts are pricey, but still available. The intake and carb combo alone is reported to bring you up to around 160hp, which well exceeds the 302 of the time.

There was reportedly a rare turbo 2.8 setup available that I'm aware of (Spearco AK Miller). I loosely modeled my 2.8 custom turbo build after it (I did a write-up here some time ago). She screams now.

One more resource 2.8 owners with more than the usual sewing-machine ticking sounds (even after valve adjustment) might be interested in is here:

Those shafts commonly wear and have sent more than a few 2.8's to the junkyard prematurely. I picked a set up a few weeks ago to keeps as a spare, they're inexpensive and are only getting harder to find.

Here's a rear thermostat housing that fits, 4-seasons part 84878 (you'll rarely find a 2.8 without the bolts frozen into it, or the threads stripped out -- if you ever need to change your thermostat or water pump, you'll want one):
Amazon carries it, you can also find it on eBay and elsewhere.

And last but not least, here's the only currently available, proper clutch for the 2.8 with RAD4:
