used motors..
I've had similar scenario's..I usually find another complete truck that runs good but is rotted to death for less than 500 bucks..(though in Pheonix,that is unlikely,sine nothing rusts out there!

)..a used motor in good shape can be had for 500 bucks I'd assume..
I buy a whole vehicle for one reason-I now have all those parts I'd normally have to scour a junkyard for,like throttle cables and brackets,(lost count of how many times I was able to put a motor in,in just a few hours,only to find I couldn't hook up the throttle cable and detent cables!)..or an exhaust manifold is different,P/S pump,radiator,etc..since your doing this on a weekend,its nice to have ALL the parts between the two trucks --that way its nearly gaurenteed you'll have everything you need to get it running and driveable by monday morning..
Then you can strip any other spare parts you need off the cannibalized truck,and either sell them to recoup some cash,or keep them for your truck..then junk the "shell" at a scrapyard for a few hundred bucks..
Only trouble with doing it this way,is sometimes the "parts" truck is in better shape than the one that needs the motor!

--more than once I was unable to bring myself to cut up the "parts" truck,and ended up buying a THIRD truck,to fix the first one with a blown motor!..then I fixed up the "parts" truck and kept it,since it was actually in better shape than the one that blew the motor..and I sold that one instead!..
