There is only one Q-jet intake available and it was only made for two years, 1985-'86. It's a heavy cast iron dual plane piece, has EGR and a heat crossover. It works OK for mild builds. | There is only one Q-jet intake available and it was only made for two years, 1985-'86. It's a heavy cast iron dual plane piece, has EGR and a heat crossover.

| − | There are several marine intakes, both for the Rochester 2G-type 2-barrel and the Q-jet and Carter squarebore (uses an adaptor) 4-barrel, all cast iron. In fact the only aluminum intake for the V6 Chevy 90º is a 2-barrel single plane(!) piece that was used for several years on the 200 and 229 cid engines. Not a performance-oriented part, it has a bolt pattern for the Dualjet (basically the front half of a Q-jet), which means no other carbs will fit it and there are no adaptors, either. | + | ===Marine intakes=== |
