I finally got the small-block out my chevelle and after some minor freshening up it will go into an s-10 pick-up truck. The transmission that I will be using is a powerglide because that is what I have laying around. I have heard that automatics prefer a wide LSA while manuals prefer a narrow LSA. Is this also true with a powerglide? The truck will be mostly a beater and will see the strip occasionally. I have several cams that I could use. The cam that is in it now is a 106 LSA. The one that it replaced was a 112 LSA. Any input? Thanks.
