I just sold this setup a month or so ago. I got it in the deal with my ‘28 coupe, brand new. It just didn’t fit the build style of any of my cars. I thought about using the carbs on the 375 hp 396 bbc I have under the workbench until I saw what the bbc Chevy tri-power manifolds go for these days, yikes!!
In the case of the FE setups, the 3x2s were stronger than the factory 1x4s of the day- but if you've ever seen those old 1x4s, they are very flat and not too efficient. The low riser 2x4 was a pretty good step up, but still pretty "low"- but can run quite well on a street car. The good one for street (and brackets) use is the "regular" medium riser 2x4, which is what is on my Galaxie- they run very well. Then you move up into stuff like the Tunnel Wedge, and start giving up low end for top end boogey. Hard to beat the looks of any of them. There are folks who can make the 3x2 run pretty well, but it takes a huge amount of work, different carbs etc. On that note, my next-door schoolmate, Larry Kirkum, has been doing pretty well in FAST racing with his '68 427-435 3x2 Corvette (not an L88), running 9.50's on Wide Ovals https://www.hemmings.com/stories/20...turn-9-second-passes-all-day-long-in-michigan
Yeah, he took machine shop in high school and has done very well. FAST class is interesting, has to LOOK stock, but inside, lotsa goodies
3x2 looks very cool. 2x4 gives more power and is easier to maintain. Aesthetically speaking - I think 3x2 is Hot Rod esque, while 2x4 feels like a racer. They both are pretty fancy setups really. The engineer in me struggles to get behind dividing 6 barrels into 8 cylinders, but that is simply my own neurosis bubbling up
I like 2x 2bbl holleys....on a 2x 4bbl intake. Typically without a blower. I like the early offy dual 4, or TR1X Tunnel ram.
