Howdy y'all, nephew n' I are doing a motor swap. Dentsides all the way,1973 360-390 motor to a '78 300 inline 6. We got the 300 out of an 80's model econo van, put it in the '78, but now we want to put the 300 into the f350 and take the 360-390 n' put into the '78 f150. I think they both used to have a.c., but not anymore. Just wanting to know if there are any major problems that we're up against? Yes, we'll snap some photos for everyone to observe. This will be fun n' we want to share it with everyone. Cause that's what FTE.com is all about yah, woo, yah!!! Thanks for all your help n' suggestions...
