LT1 in a 1990 Vette?

I recently bought an LT1 out of a '93 Vette and was planning to install it in a '90 Vette that had an L98 (I believe). I have the engine, transmission, wiring harness & computer, but I was told my dash gauges will not work with this computer. Is this true? If so, what can I do to make it work?

Thanks,
JD

Actually, I'll be adding 300 horsepower with an LT1! Currently, the '90 has no engine or transmission. I bought it as a project car.

Cool. Maybe you can get a LT1 dash so the gauges work.

You can do it, it has been done before. If you have a complete wiring harness, you may be able to use the '90 dash? but you may need to change out the cluster. You will definatly need a '90 FSM.

Good luck, and keep us posted.
