One V8 hot-rodding trick of the ’50s that never quite caught on was the 5×2 carburetor setup. But you know, it’s not such a terrible idea.
The photos we’re sharing here have made a few laps around the hot-rodding message boards across the internet, where they never fail to stimulate interest and discussion. The images depict an idea that originated in the early-to-mid-50s for souping up American V8s: the 5×2 carburetor setup, with an intake manifold specially cast (or modified from a production component) to accept five two-barrel carburetors. While the configuration never really caught on, it’s not as strange as it may look today.
The system above, apparently built up from a production Pontiac V8 intake manifold, uses five Rochester 2GC two-barrel carburetors laid out in an X pattern, with the center carb in the original stock location. The early Oldsmobile (1949-64) manifold in the lead photo is of similar configuration, and also includes Rochester-style carburetor mounting flanges.
1950 Chevrolet 6 Cylinder with Speed Equipment, alternative Hot Rod power?
Saw this engine for sale on Hemming’s and it occurred to me that this would make a really cost effective alternative to either a hopped up four banger or a Flathead V8.
If it’s to go into Model A or B, then any Ford v Chevy sensibilities would need to be put to one side.
Based on the engine number: HAM196465, this appears to be a 1950 216 ci. It has Offenhauser valve cover, Newhouse intake, 2 Rochester carbs with linkage, Fenton exhaust.
This engine was running in a 1954 Chevy when I bought it many years ago. I bought it to go in an early Chevy pickup, but never used it. I have not run it since I bought it. Does not include engine stand. Would be best if you pick up.
This Winfield intake, Cyclone adapter (to install a Stromberg), and RayDay cylinder head were removed from a Model A in 1956. Images courtesy Evan Bailly and as noted.
We are suckers for vintage speed equipment. The hobby of making inexpensive cars faster goes way back—it predates the term “hot rod” by decades. While some names have been around for ages and are so well-established that they’ve become background noise, there are far more companies that tried to enter the business of hop-up parts and didn’t make it. Some folded their tents entirely, but others had come from the more-general auto-supply business and returned to that.
