[Dave at Pelican Parts]

I think that the SBC motors are all pretty much dimensionally identical to each other. And since we know that some SBC motors fit, most or all of them should fit--if some of the accessories can be dealt with. Renegade Hybrids in Vegas has been doing these for decades, and knows their stuff. Much of their parts can be purchased through Pelican, though if you are having someone else do the work it would probably be best to go through that person. Or just ship the car to Renegade...

The axles, CVs, and transmission become very possible failure points when you start running V8 torque through them. There are solutions, but they can be somewhat costly. Or you can make sure that what you have is in good shape and then be careful about what you ask of the parts.

Dave is quite right about the gearing--Porsche doesn't even make a tall enough gear for the 914's gearbox that allows happy V8 freeway cruising. So a number of people will take something like an "H" gear and run it "backwards", flipping the drive gear and driven gear to the other shafts. Which, of course, is not free, and generally winds up being part of a transmission rebuild...

It can definitely be done, though. The problems are pretty well understood and there are solutions available. And there are other options, like the Scooby motor already mentioned.
