Re: Converting '82 2.8 v-belt to serpentine?
Actually, after looking more closely at mine, don't understand why you can't run a serpentine pulley on the waterpump while keeping rotation stock w/o changing anything out. If serpentine belt follows the stock v-belt route, and ONLY running something like an alternator in the stock location, it should work and alt can take up belt slack if nothing crazy w/ high amperage is used; higher amperage, add an idler that can be adjusted to add tension. If running PS, AC, etc., adding a smooth idler to the lower right 4:00 o'clock area of the alt, and hooking it over that you could grab the rest of accessories in upper right of engine.
Anyhow, ended up retrofitting the 85 amp Subaru alt. Was close enough to work using factory mounting locations and a 2 wire as well. Already added a heavier gauge charge wire from alt to battery, so that tiny 14 gauge stock wire that ran back into the harness instead of going to the alt, won't get overtaxed, but had to fiddle with idle as it spun too slow to get a full charge. Running cooling fan ('95 Subaru Legacy 5 blade, 2 speed set on high speed, which is still extremely quiet, heater on, lights on high, alt seemed to tolerate it and belt wasn't slipping). Everything was free from Subaru donor, so why not. Whatever engine/trans donor is used for the V8 upgrade, will get all the correct bits sorted.
The biggest thief is time.
