Are the TPI runners on ALL L98 engines the same length, diameter and part number?
Can anyone tell me the part numbers for the TPI runners for an 86 with aluminum cyl heads?

Here's the deal:
1985-88 left side manifold (tube assembly)= GM #14081007
1989-91 left side manifold (tube assembly)= GM #10108467
1985-91 right side manifold (tube assembly)= GM #14081008
How the 14081007 differs from the 10108467 I do not know
The GM #14081007 was discontinued without supercession in June, 1995
The GM #14081008 was discontinued without supercession in July, 1997
GM #10108467 was discontinued and replaced by GM #10108469 in September, 1995. GM #10108469 was then discontinued without supercession in August, 2000.
Joe, I assUme those are all Corvette parts. The L98 was used in other applications, and I believe there are differences between intake tubes for those applications and Corvette.

Yes, these are Corvette part numbers. The part numbers for the L-98's used in Camaros and Firebirds were different.

Joe - thanks much; that's exactly the information I was looking for.
FWIW, 85-88 MY has a 9th cold start injector which was eliminated from 1989 onward. Here is a photo of the different runners.
