    need help with swap 4.3-5.3

    ok i got the v6 out and am currently in the process of putting in the 5.3...the motor mounts look to be in the wrong location...the engine is bolted to the trans and it seems that the engine needs to go back about 1.5 inches for the mounts to line up...anyone else had this prob...i am using the mounts for the 5.3...the engine is from an 02 and my truck is an 02 any help would be appreciated...oh and i also need a EVAP solenoid...if anyone has one...thanks

    You just have the wrong mounts. It took me like 3 or 4 tries to find the right ones. I put up some part numbers in the threads from my swap and they should be the same. 99-02. It took me a few days to find the right ones. Luckily the parts manager down here at the dealership was a real big help and got me the right ones. They werent too expensive either

    check your pms banker. those are just the motor mounts, you need the frame mounts as well. like ramsey said make sure they came out of the 1500 trucks. If yours is a 4wd then get 4wd ones, if not get 2wd.
