Re: 196 differences

[farna@xxxxxxx]

Just to clarify, Andre means the 1963 American is the oddity -- it uses the front/rear engine mounts but has a block with side mount bosses. It will take any 56-65 195.6 as long as you have the original engine to get the front mount plate off of. The mounts are the same on L-head and OHV engines, so I literally mean ANY 195.6.

Cranks interchange among all 195.6 engines also -- except for the flange as Andre pointed out. But you can use an auto crank with flat flange in a stick car as long as the pilot hole is there, and can probably have the "volcano" macined flat. I don't know of anyone who's tried the later, but a machinist can look at the crank and tell if there's enough room. Don't know why the "volcano" is there unless the old trannys (pre 63) had a shorter input shaft and the "volcano" held the pilot bushing. 

I remember the trouble we had finding a cam and bearings for the 195.6 in my old car (that Andre rebuilt for the new owner). Neither of us knew there were so many changes made to the 195.6 over the last 2-3 years it was made! Apparently the AMC engineers were experimenting with different size cam bearings... who knows?
