I read something Pablo posted before about there being two different tbi intakes. He said that the one with 182 at the end of the casting number has a taller plenum. I'm curious is that really the difference and who got what manifolds and for what reasons. I've got the 182 on my '89 formula.

Ok I saw a 91 Camaro RS with the other intake, my 89 formula has the #182 intake. Maybe it's a bird vs formula thing? I can't tell much of a difference except for different casting numbers and the numbering and lettering being a little different.
