That's a screamin deal on the v8. Are you going to make this into a daily driver? Does it have to be smog legal for you? Add up everything you THINK it will cost, and then figure at least double that for the bottom line. There is a lot of stuff to take into consideration. Personally, If I was going to do a swap in an 80, I would want the torque of something closer to 6 liter displacement for a 3 ton station wagon. JohnI have an option to buy a 5.3 for 400$ with comp and wiring harness. Now my question is how much should I look to spend past that cost? I have decent knowledge of working on stuff so hopefully labor wouldn't cost me much.
I would suggest getting a GM trans though, and then an adapter to the toyota t-case, or get a NV4500 and an adapter to the 60 series split case. Then you can go part time 4wd, and have a manual!
I have a 62 tcase, converted to manual, in mine. I wanted part time 4WD. It was cheaper to buy the tcase, have it rebuilt, and then get the adapters, than do a part time in my 80 case.
well, you will gain a bit for mileage, most people say that the steering feels a little lighter. I got my with the cummins in it and swapped to part time with 35's (now 37's). There doesnt seem to be anything easily noticable based on the handling from full time to part time is what Im trying to say.
The biggest benefit is wear on parts, though living in a northern climate with snow or ice on the roads for 6 or 7 months of the year, I would prefer full time, though then it may not be suitable to upgrade to long's in the future.
