so i have the 5.7 sitting here and the motor and trans out..where do i get the motor mounts and what radiator do i use for this set up....does the stock y pipe hook up to the ex manifolds for the v8? or do i have to build a new ex system? talk to me i know some of you have this done already....i want to surprise a few 5.0's in baltimore:smokin:

What year, make & model are you wanting to install the 5.7L into?

sorry i thought it was in my stats... it's a 88 astro cargo with a 700 r 4...i am having the trans work done now...sorry i did not get right back on here and check for a reply right away....you can also get me at yahoo if you put 3 after captinhowdy for a faster response

Suggest you head to www.astrosafarivans.com. Tons of guys have done this swap there. Many have even used the stock V6 radiator IIRC.

I can ask. I know the guy who built this and used to drive it:
