boy, the headaches just never end with this motor. I found out that a motorhome motor like my 1968 318 is more of a different bird than I ever imagined. Not only were the heads and intake different (water heated instead of exhaust), but the water pump placement (via the timing cover) is different, got all that changed out, went to put on all the pulleys and front accessories and brackets only to find out that THEY are all different too. crud!!! so I went and put an ad on craigslist asking if anyone had a complete 318 with all the brackets, accessories, pulleys, ect, so I could get a complete matching set. Fortunately a gentleman about 20 miles away from me has a 69 Satellite that has all I need and still on the engine so I can even take pix to make sure all goes back the same way. I will get them this upcoming weekend. Just another small blip on the radar screen of life.... at least I now have the heads, intake, rockers and manifolds on the motor. some progress is better than none
