Lou54,
I have installed a 230 and later on a 292. As other have said, it all depends on how you want to mount your engine and trans. If I remember right my 235 that came with the truck was mounted with a front mount below the harmonic balancer, and the the mounts on the bellhousing. This is how I ended up mounting both my 230 and my 292, forgoing the side motor mounts. Since I went with the SM420 trans, I was able to keep the bellhousing mounts and not have to worry about a trans mount. Luckily I had a friend who had a rear end from I believe a 55.1 truck (which had the open driveline), so I was able to swap that over for a near perfect fit. If you went with a more modern trans (like the T5), then the mounting situation would have to be figured out for that... something I may or may not end up doing way in the future.
For my 292 rebuild, I went through my local machine shop to get some of the parts (bearings, reconditioned rods with ARP bolts, pistons/rings, oil pump, etc). I went through 12bolt.com for cam/lifters/valves/springs and lumps for the intake ports. Local NAPA for gasket sets.
There is a lot of good info on these motors out there, 12bolt being a good source for info and parts. Leo Santucci has a power manual (focuses more on the 292, but does have some good info generally).
Feel free to message me for any additional info you might be after, I'll do my best, but I'm not nearly as knowledgeable as some of the others on here.
