Are plenums and runners interchangable from an '86 TPI 305 and a '91 L98. I just put a '91 L98 in my car and while Im driving my car, I can polish and port my plenum and runners from the 86 intake then just switch the two.

Maybe then I'd polish the '91 and sell it.

84-88-these have a cold start injector that is attached to the driver side runner and has a fuel line that runs from the cold start injector(9th injector)to the back of the driver side fuel rail.these two holes can be plugged for use in later model cars

Bandit: I you mean 85-88, there was no TPI in 84.

You will also need to drill a port on the back of the passenger side of the plenum for the MAP sensor that the 90-92 TPI uses.
