before u get yourself into anything i would just like u to think about a few things first.
is the 5.7 rebult or new, cus if it isn't then do that first.
next, is the engine dune up?? if it isn't then all ur doing is adding 30 hp with extra weight of the engine.
i don't want to discurage u but i want u to know that it is alot of work.
trust me i know.
i have a 93 1500 that had a 4.3 with a five speed manuel,
i did the engine swap in my garage by myself.
after i was done i had small electrical problems and some others,
to make a long story short, i'm putting the 4.3 bake in.
if i spent the money on performance parts for my 4.3 i would have been much more ahead of ware i am now.
i have way more info on it, if u want to know e-mail me at
