well after doing some more searching i think im going with the 2.7. i found one at the local bone yard i talked to them and i think i can trade for it i just need to figure out what i need from them for the swap. the 3.4 go for about $800 more then the 2.7 around here. so this is what i need motor all the wiring im geting the entire truck harness, maf, pcm ,every thing from the engine bay, the w59 bellhousing, clutch, slave cyl.  anybody think of anything else i might need? also i cant find any thing on what fuel pump i should use i have a fuel cell so i need a inline pump but which one? o and the 2.7 is a 98 with 114,000 miles. i still havent got the 3.4 pulled all the way so i still got a few days to figure out what i need. any imput would be great. all this searching is making my brain hurt.
