Hopefully this doesn't get deleted immediately... I realize this isn't completely 3rdgen related.

I have an 89 s10 blazer with the tbi 4.3. I'm doing a solid axle swap and will be wheeling this truck a lot, quite a bit at odd angles. I'm interested on the ideas of some of the guys here.

How hard would it be to pull the tbi unit off, tap injector bungs into a stock or aftermarket carb manifold and run a multiport setup on the 4.3? What computer should I run? What computer does it have stock? Couldn't a late model chev truck vortec TB be adapted because of the built in tps, iac and map sensors?

 

You might try this article here... The '89 Blazer 4.3 uses a '7747 ecm doesn't it??

Thanks!

I'm not sure what ecm it is yet. It looks like it's a sealed unit mounted in the engine bay but I could be wrong and that could be something else, it did look a little small...
