Hello, I'm not sure if I'm welcome here? I have a 1940 Ford with a 425 dual quad motor. I came across v8buick and thought it looked like a very informative site, as I will probably have a lot of questions. Even if I need to go somewhere else, I thought you would enjoy the photo of my engine. My wife's family has owned many Buicks, as her uncle was a Buick dealer. Thanks, Roger
The engine has what appears to be a factory intake (partial casting # 37031, I think). It sports a pair of Edelbrock carbs (not sure what size) with progressive linkage. I'm hoping to find out more about this engine. It runs great, sounds great. It's backed by a TH400.
I saw another black 40 at a local car show just yesterday. It was powered by a 327. You very seldom see a 40 with Ford power although another one local has a 427 Ford under the hood.
Very nice! Welcome to V8 Buick. A friend of mine has a '40 Chev with a 425 Nailhead, also had one in his '37 Pontiac and '50 Ford pickup! It's a neat engine no matter what it is in. The carb number will be on the front of the mounting pad, passenger side. A pair of 500's will work, but these engines like big carbs, 625's are closer to stock size. Most 425's had a slightly more aggressive cam, 109 degree lobe spacing vs 114* spacing for later 401's. Buick switched to the 114* cam in 1966 due to customer complaints about a 'rough' idle!
Wow!! That is one pretty car!! My 66 GS's 401 was was pulled from the junkyard in the late 80's from a man who also planned to put it in a 40 or 41 Ford pickup also, only found out and met the man when he answered my add later on for all my other nailhead motors and parts. Some small world kind of thing "well sort of as we were in the same state I believe to this day someone has my old motor and parts and is on this forum??? Anyone know of a man who was a Postal worker in MA back in the day with a nailhead Small world and that's all I remember..
I had another 40 Ford a while back with a 351 Cleveland. It was pretty cool. A friend has a Windsor in his
That is a beauty. I have afew 425s in cars and love them. The sound is different which really makes people wonder whats under the hood. That is all dressed up which really makes for stunning looking power plant.Welcome to the right place for Buicks
Do you know what year trans it is? The 1964 had only 'low' and 'drive', while the 65-6 had the 1-2-d positions. The 65-6 also had a 'switch pitch' converter that could be switched from low stall to high stall ! The 12v switch is usually built into the throttle linkage so you may not even realize it's there. With an additional switch, you can manually select high stall for off the line performance, and low stall for economical cruising. It's a real neat feature that was only used for a few years.
I'm trying to get a hold of the previous owner for more info. He had a shift indicator sketched out which is the standard prn321...
1940NH. Do a search on this site/forum. How to ID a switch pitch converter. Look at the tag on the right side of the trans. for a tag. This will tell you year, make & model. Maybe someone can point you to the site. There is SOOOO much knowledge on this forum it will blow your mind. AND people who are willing to share their knowledge. Tom T.
Oh yeah, if it is a "switch pitch" tranny not setup, then you are in for one FUN surprise if you do set it up
