Some "Dime Rockets" for the 4TH!

I had a 79 Monza V8 that I bought new and it had a 2GC. However, the intake manifold number was 373598 like is listed for the '78 engines. I have also seen 79 Caprices, a 79 Firebird, a 79 Skylark and recently a 79 Nova with 2GCs, never a DualJet.

If you look at NHRA's sheets, they list the same intake manifold for the 267 with a DualJet and the 305 with the 2GC; is that possible? (I am not familiar with DualJets, other than they look like the front of a Qjet.) Also, is either of the 79 intake manifolds (14007372 & 14007374) aluminum?

The 78 alt intake 346260 is also used on the 76 and 77 305s, and the 75 and 76 350 2bbl. (Probably the 74 also; the tech sheet says 346266 but that could be a typo.)

Agreed.

No. The dual-jet and the 2GC have a different bolt pattern. I've had a 79 Caprice and a 79 Camaro, 305s both that had dual-jets on them. I wouldn't doubt that it has something to do with where the cars were built and what plant supplied the engines.

I did a bit of research last night and found that the two intake manifolds listed on the 79 tech sheet are both for DualJet. In fact, I physically inspected a 14007372 number which is cast iron. I'm going to chase down the carb numbers next. Billy, I think you are probably right about supply and model usage; maybe it has to do with timing in the production year, too. My Monza was ordered in September 1978 and delivered in October.

I've been running the 82 267 Monte Carlo combo for a year now and I have to say the intake manifold on this car has to be the world's heaviest for a small block chevy. Love that dual-jet too. '

Been looking at some of these U/SA combos such as the late 70's Camaro with the 305-2V and the 80's combos with the 267-2V . At 180 HP vs. 150 for the 267 is it worth carrying the extra 600 lbs. with the 305 ? Which is the better combination and what other chevy combos may be the way to go for U ?

Bill, there is an aluminium intake available. I just don't remember which one it is.

How does one go about fixing this? The tech sheet calls for what looks like the 2GC though the intake is not?. I could swap grilles and make a 77 ( have to change header panel too) or 78 (run in T) but the 79 is a favorable U. Looking at a 79 Caprice 2dr, the funky sloped back window version.

[Billy Nees]

Make it a 77.

[Dwight Southerland]

77 is a big change with the bumpers. What's wrong about the '78? Run it as an LT and it is still in U. Much easier change.

Are you discussing Camaro or Caprice ?
