This is a great thread; I've been following it for awhile, and finally have to jump in with a questions that I'm unclear on after reading the whole thing a couple of times: do the pre-85/pre-turbo gearbox bellhousings with a SAE pattern really exist? I found a reference on another site (
http://cruisers.shoumatoffmedia.com/4bd.html) that Isuzu used to make an
adapter that allows SAE #3 bell housings to be used (gearbox bellhousing, I assume)- is this the same thing? Wouldn't this simplify things greatly if you wanted to use a GM transmission?
Also, the discussion about whether body lift is necessary is a little fuzzy to me; assuming you want to keep the engine off the firewall, how much lift would you need for oil pan clearance? (I'm not a big fan of body lift, so less is better!)
Finally, are engine mounts commercially available, or would they have to be fabricated?
