Anyone have any idea on the differences, if any, between these motors? I'd really appreciate the help!
Thank you! That is exactly why I'm asking lol, I did notice the heads were different, so Ill have to look more closely at the 2.Check and make sure the 86 heads have the threads in them for the serpentine belt system. If not, your stuck using the v belt unless you have conversion kit. This is the problem I'm running into with the 72 350 that I'm going to run. The double hump heads don't have them. Otherwise it's plug and play
