I'm just wondering how poorly that camaro must be running with carb swapped on to it. Could be an easy fix, depending on how badly is was hacked to run it in its condition. Might be easier and cheaper to find an unmolested 80's-90's tpi/tbi engine to swap in instead

1990 could have came throttle body or tuned port. Either way, a correct set of matching components is critical to run properly including cam choice in current engine.First off if the iroc still has a computer &( a mess of unused wiring under the hood) , you may be able to use most of it. The computer should have a part # that a parts store could verify. Also could use the vin #.
As far as finding a good condition 350 tpi complete setup, that could be a little hard now at the age their getting. Few factory setups , other than vette were 350 tpi.
This is also a labor of love type of project.

JL most IROC's were factory TPI cars, the TBI's are few and far in between
