So on my 80 CJ7 the transmission is Kaput, shot, and needs to be replaced. The Dana 300 is in decent condition, but could use a good going through and cleaning up.
I have decided that I am going to use one of the NV4500's that I have in the Jeep, but where I am stuck is figuring out what I am going to do for the motor in the long term.
Currently the Jeep has the original 258, it runs strong, sounds good, leaks a bunch of oil out of the pan, rear main and valve cover, but it it is certainly not beyond repair.
My options are when I drop the transmission I can either clean up the 258, install a new pan gasket and rear main and valve cover, and continue to run it until I can rebuild it with a 4.0 head, EFI and some other goodies, in fact I can get a complete 4.0 with a bottom end knock but good head for 200 bucks. I was even thinking about doing a stroker with a cam.
My other option is I have a Chevy 350 that came out of an 89 suburban that runs like a top. It is a little ugly on the outside because it has been in some salt, but it will clean up just fine. I have the throttle body, all of the accessory drive and goodies for it, id just have to drop it in.
Either way I go I will have to buy a bell housing because I don't have one.
I am really wondering which is going to be my best bet for the long haul.
I know the I-6 should get decent fuel mileage running the 33 11.50's and 4.10 gears, I will be at 2134 RPM @ 70MPH, 1981 @ 65MPH.
The jeep is going to be a daily driver that will see regular trail use, I am going to be driving it to Alaska in the spring, and it will be my primary mode of transportation when I move there.
I would really like to know what those of you who have done similar swaps think, what you liked and what you did not like.
