I received a PM from Shmabs asking to humor him with where I planned to source parts to do a conversion.
To be brutally honest, I'm one patient son of a gun. I held out for almost a year waiting for the right deal to come along for the drive shafts. Local guys wanted $250+ EACH for the shafts, but I had both shipped (from Alabama to Texas) plus some other parts I needed for a budget friendly $180. I've seen the GM to Toyota adapters (normally $1000-ish new) sell for $350. I'd wait for a similar deal. The adapters are solid chunks of metal, as long as they're not broken in some unlikely way, they're not going to be bad! I'd most likely keep as many stock drive train components as possible to avoid the 'can-o-worms' effect. The LC transmissions and transfer case are easily capable of handling the power of the modest 4.8 vortec, plus some. The only thing I'd really need to buy new is the wiring harness adapters.
My earlier numbers regarding only needing a few hundred dollars more really indicates the wiring harness. I bought two 3FE engines for the price of 3 decent, low mileage 4.8 engines, or two decent 5.3s.... I will say that it's nice that all of the 3FE stuff slips in and bolts into place in the engine bay. But the reality is, this truck is over 25 years now. The engine puts out approximately 155hp and 220ft lbs, vs +100hp and +70ftlb for the 4.8 vortec. With the potential of getting 20mpg on the hwy.... vs hopefully 15.
Can I stop in at the Oreilly in Rock Springs, WY and pick up a starter off the shelf for my 3FE? I doubt it, I was lucky that they had one start for my Montero! Now, given a 4.8 or 5.3.... they'll ask "which choice of starter would you like? We have 3 dozen brands to choose from. Brand new for $20 each. Or, go to Wal-Mart and get the "Great Value" brand for $10." -Slight exaggeration and a load of sarcasm, but you get the point.
The good news is that I'll be able to enjoy driving the truck for now (well, soon) while I start collecting the parts needed to do the conversion. I just need to find a plan and stick to it.... like I've done with the 3Fe.
Ian hits on quite a few points in his recent thread,

I could go on and on.... but, that's all I've got to say about that.
