I'd love to do that to my Astro, but as Kps396 said, I just can't kill the 4.3.
There are all kinds of swaps that go into 2WD Astro/Safaris, but the issue with swapping into an AWD is that there are no
options concerning front torsion bars. The new engine needs to be of similar weight to the 4.3, or you will need helper shocks to take the added load.
Any idea how much the 2.8 weighs?
The 2.8 weighs just around 500lbs. Iron block 4.3 has to be around the same? I understand the 2.8 is an expensive swap but there is a $1500 discount on it right now from this site...yes this 4.3 is a 211,xxx mile runner and still going. I suppose I get the mill a total rebuild along with the trans for less than the cost of the discounted 2.8. Just love the idea of that swap.
Astros are amazing little vans, we love ours! Around here the 16" AWD vans bring $6k+, more if they are lifted, campered, etc.
I just had the 4L60E rebuilt on my Astro, so maybe when the 260K mile 4.3 finally gives up, I'll find a 2.8 Duramax...
