Cbaymac,

I think you can find those 4.3's in most Astro vans, and alot of the S-10 trucks and blazers.

It appears from Houston's perspective that the Monte Carlo swap is pretty extensive.

Have you considered an S-10 swap. There have been a few discussions here lately on that topic. You might be able to pick one up with the 4.3 already in place and have alot less work to do.

Here's something related I saw on E-Bay the other day.

Looked kind of neat.
