Just ordered a Mark's Adapter and the needed clutch parts (I recommend Cruiseroutfitters.com if you are looking, they beat everyone's price and Kurt seems to be a hell of a guy) today and will be doing a V8 swap when they ship. Obviously I'm mating it to the stock manual 4 speed tranny (heads up to those who don't know), but what I was looking for was some feedback or comments from anyone that may have done this or used the Mark's Adapter before. I have a very proficient and kick ass cruiser mechanic/ cruiserhead doing the work, but in order to help things (or at least try to) go smoothly, I want to hear from anyone who has used this and maybe get a heads-up on possible problems to look for. He has many extra 60 trannys to use, so chewing up the stock tranny is not a big deal, if it should happen. I hear that this is the best way to go, no drive line mods, etc, etc. But I never hear how easy/ difficult it is or isn't. Any comments will be appreciated.
