well guys, what do you think?

I would fix the injection... here is a snip of my comments for our records!

----------------------------------------------

ugh... going to carbs... that is the most bass-ackwards thinking. I don't agree with it.

And it has nothing to do with being a "purist" it has everything to do with building the right engine.

The car was a mess, fine, but there are ways to repair this. First off, I am curious why the tuner can't tune it. That bothers me. The 91 ECM is pretty good. I know it's SD, but it could be converted over to MAF, so that's not a problem.

Also, harnesses are not that expensive. I would call Contemporary Corvette, Corvette Salvage (Dino's) or Painless and see what they have.

The other option is to do a FAST system, which might be your best bet.

Unlike Rich's 84, where upgrading to a carb is a good idea, I am not so sure with later injection systems.

Carbs are not as tunable as you think. They are analog devices that work great within a power band, but that's about it. EFI is so much more linear and is capable of dealing with altitude differences much easier. It is intellegent.

Then again, you would loose much of the dash board, and the ABS might just barf. The later electronics are much more integrated, the CCM is expecting a signal so it can communicate with the EBCM... this just gets ugly.

To me, it would be easier to update the injection, fix or replace the harness and be done with it.
