Thanks Jake. I grew up there and still hang out there. They might be able to help me since I would like to keep the stock transmission to keep costs down as much as possible.
Curtis,
Yes the 460 is singing it's death song too, but it might find it's way into a 1969 F-350 farm truck since it has less than 60K on the motor. I wish I could find a good 12 valve that's in the 96-98 year range that I could afford. I have found a place that sells new drop ins for $6K.
The only problem right now is getting enough information to make an informed decision on what to use. The motorhome has been well taken care of since we have had it, but it has seen better days. This is not going to be just an engine swap though. I'm going to try to modernize it inside and out as much as I can without destroying a fairly good floorplan.
The work will be done in my Dads 30'x60' shop at the ranch. That will make it nice since he has accumulated all the tools I should need for this project. Thanks for the offer of help. I'll take you up on that!
Have a great day and thank you again for the help!
