I did a 4.3 to 4.3 swap in an astro van for my dad this past weekend. I went ahead and pulled the old wiring harness off the donor van, and have a complete fuel injection/tranny setup for a 4.3 ready to use in something. I can find 4.3's locally for under $200 all day long...
Now...
My 1.6 is shot in my tracker. It has a rod hanging out the side of the block even. The cheapest one I can find anywhere near my house is $450 w/130k on the odometer. I now wanna install a 4.3. I can fab my own mounts, crossmembers, driveshafts, etc... for a 4.3 swap, and I can use the wiring harness and fuel injection from the van. It's easy to find 700R/4L60's and 350 Turbo's if I ever have a prob with the tranny... (I have had 6 in my '94 camaro, I know they are easy to find). I think I can do the swap perty darn cheap...
The downside, the rest of the drivetrain. I am just gonna do the install, then deal with the breaking points as they come. It might cost me a bit in the long run, but overall I'll have a powerful little ride. :-)
I have done multiple searches on doing a 4.3 swap, but haven't really found anything useful. I remember seeing a link to a site with a 4.3 Votec in a tracker, but can't find it now. Anyone have any good links that might help?
