| Re: 88 with 2.8 and puting in a 97 ls1 I believe you have an LT1, not an LS1 - the LS1's were in the 1998 and up cars - my 1997 Z28 has the LT1.
The tranny from the 2.8 litre car will not work - it is a V6 tranny will not bolt up to an 8 cylinder motor, and even with a new bellhousing to bolt it up, the 6 cylinder tranny wouldn't hold up to the LT1 power for long without breaking....
UNLESS, it truly is a V8 tranny that had the bellhousing swapped out to a V6 bellhousing in order to be able to install the 2.8 litre motor.
BUT - I highly doubt anyone would remove a V8 motor (what should have been stock on an IROC), and swapped in a V6 motor. More than likely, it was always a V6 car and someone swapped badges so it had IROC emblems on it. Check the VIN for the car, and decode it according to the chart at the home page of this site so that you can verify that it was a V6 car originally.
