From what I read, I don't think there was a dealer installed 401 Dual Quad. They where all on the 425's and where about 360 horsepower and about 465-480lb/ft. Why? You got one? :Brow:
Bill, You could get a dual quad dealer installed on the Skylark. I'm sure there weren't many done, but it was offered. Mark
Oh. I stand corrected. I've seen this question come up a bit on the NailheadBuick group over at Yahoo and that is the response that is usually given. In fact just as I was writing this post the response quoted below was received (spooky)...
401 8v To my understanding you could order a 401 with dual quads on the 66' skylark GS from the factory. When the car arrived the carbs and intake were in the trunk, thus being dealer installed.
Matt, Unless someone appeared with all the paperwork from new that proved that is how their car was ordered and the parts were in the trunk, and the dealer did install them, I would put that in the "myth/legends/wifes tales" file. The parts in the trunk stories kind of go along with the Corvette in the barn, but was advertised as a Chevy urban myth. Mark
Didn't the Super Wildcat motors also have a slightly more radical cam? As an aside, I had one on my 4spd for a few years and it was a very sweet running setup. The progressive linkage allows you to open it up in stages. I noticed an appreciable gain in power through 6 barrels, but when I opened up the last two, it made more noise, but no more power on my stock 401. A built motor with ported heads and a cam might be able to use all 8. Dan
