TBI to Fitech Swap

[WalkeJ1]

If this question has already been asked I couldn't find it in the search function. I have a 91 RCSB with a 5.7, thinking of replacing the engine with a pace performance 383 crate engine with Fitech 600hp system. Is there any way I can use the factory gauges with the Fitech?

So since the gauges are controlled by the ECM the answer is no?

1988 through 1994 are all a standalone system for the gauges. Nothing to worry about.

If you end up doing the swap and keep the moonies you should do a writeup on the install.

X2. I have considered this swap myself if I go any further with mods on my 383. I have parts on the shelf to go bigger with air and fuel delivery, but FiTech may simplify it.

Factory gauges will still work. they are stand alone. Pull the service engine soon bulb. Remember you have to use a different distributor. You cannot use factory distributor. You eliminate to many sensors with the Fitech.

I just snagged a Fitech 400HP system. I'll be replacing the TBI on my 383 with it.
