How out of shape would a 6-bbl car have to be to be taken by a 4-bbl car, because from *my* vantage point (from the opposite lane!) those are 2 *very* different animals! Honestly, it ain't the 4-bbl cars that keep me awake at night...

last I checked, I thought L88s had a 4 brl, but yet the 435hp engines had a 6 brl setup...so please tell me the logic there..(could a rejetted 4brl actually be ok?). Would my 69 camaro L78 be that much better off with the 3 dueces? Innocent question, fill me in.

The top level GM cars had pretty decent intakes and big Holleys. Or Quadrajets- which can be a pretty decent race carb if prepped right. The Mopar iron 4 barrel intake/AVS setup is an absolute TURD. The sixpack setup was a significant improvement over the AVS/iron 4V manifold. Forget about the factory ratings. Take a look at what NHRA rates a particular combo. No way a six pack is only 15HP better than a 4V. Just no way.

As for the GM Holley Tripower. The manifold was too low in order to fit under the Vette hood, and the plenum volume suffered. Don't forget- your comparing a big dual feed Holley and a hi rise manifold to a Tri power- pretty comparable with the edge going to the 4V. The Mopar comparison is apples to oranges.
