Any "R" series engine from Toyota (i.e. 8R, 12R, 18R, 22R, etc.). Any of these should bolt right up to the cross member and any transmission that came in an "R" series powered car will bolt right up as well. Wiring, fuel, vacuum and clutch lines might have to be redone to accommodate the new engine.
Allamuchy ext 19 on rt80..but watch for tourists and get set in spot at the upper far end ..you can See who comes from there
It depends on which way you go. I drove from Boston, MA to Tacoma, WA by staying on Rt80/90 pretty much the whole way except through Minnesota when I took 94 into Montana. Granted I had two dogs and two cats and an entire SUV full of stuff but it took us about 70 hours, stopping to sleep in the car at rest stops and walking the dogs included. If you are going to make the trip, bring something to entertain yourself through Montana because it gets pretty boring, ship things if you are moving coasts, don't bring cats unless you have ample space for a litter box, and definitely drive through North Dakota and check out the Badlands. Hope this helps!
