swappin a 292 for a 350

[RichardJ]

The '67 is a SM420 and the '72 should be a SM465. The SM465 has a larger bearing retainer and will not in the smaller hole of the '67 bellhousing.
I put a SM465 in my '67, but I was replacing a 3 spd.
I had to make a new driveshaft. I had to cut open the floor for a tall, bolt-in hump. The hump I found, had the hole too far forward and I had to relocate it. I don't know what the hump came out of, but I think it had a V8.
