Most (certainly not all) of the factory multiple carb setups on V-8's ran progressive linkage.
Most (certainly not all) of the factory multiple carb units on inline engines ran solid linkage.
Today, since for years the racing sanctioning bodies have been penalizing V-8's with 2 x 4 setups; most manifold development in the last 25 or so years has been with single carbs. Today, the single 4 is much closer to the dual four (V-8's) than it was 30 years ago because of better manifolding. However (opinion, but I haven't been proved incorrect yet), a properly selected and calibrated dual quad will still outperform a properly selected and calibrated single quad on a V-8 engine.
However, even after proper selection of the carburetors, tuning of dual quads for optimal power is MUCH more difficult than most realize.
Sometime, take a look at the calibrations used by Chrysler on their dual quad hemi. The Chrysler engineers really did their homework on these. Calibration for each of the 8 carburetor barrel is different.
And I run my dual quads for power and economy, the hood is rarely raised!
