Ok today at the big 3 swap meet in san diego i was going round buying up most of the rochester carbs without electric chockes. Well in the overflow section i found this intake here with triple rochesters and linkage. I asked the guy he said 60 bucks just get it away from me. So i asked what it was for and the response was i dont know thats the reason i want it gone to many damn questions. So i bought the thing. Then went round to some people i know and went to the h&h flathead booth but no one knew what it was. I got so far to find out its a marine application. It has chevy carbs but its way to short to be a 216-235-261 chevy motor. ITs not home made either. So anyone know what it is? Can anyone help?
dunno what it is but its obviously marine with that lean and would look cool if you bought a old wood boat to go with it but them boats suck if you have cars, you cant work on the car and maintain the boat at the same time and the boat rots away while you build a car
It looks similar to a Harper for a GMC. But the ports on yours are different. Are the elbows aluminum? I can't find any pics but Stovebolt on here has a Harper. I hope he sees this and can post photos of his for comparison.
Ok to answere a few questions. It is NOT homemade. It doesnt have any welds at all anywere. The bends seem to be aluminum Also with the harper, i did compare it with mine(yeah i got some intakes to compare them with) so i looked . It may have 235 chevy port sizes but way to short. As for snow no i dont need any lol
i don't think it's automotive, based on the angle of the carbs. the engine must have been mounted on one hell of an angle or the vechicle sat high on one end. i guess marine also.
yeah the carbs and linkage is worth the 60 bucks. The intake if no one id's it or we cant find out what it is i think i will make new tubes and run it on a 235. But keep the info comming.
you said you were buying most of the rochesters at the swap meet, do you have a rochester fetish or what?
The only time I have ever saw one like that was on a old piece of mining equipment, it was a flathead six and seems to me like it may have been a old mopar. Not saying that yours fits a old mopar flatty six, but it may have come of a old mining piece of equipment. Those things were always working at odd angles.
If it was fron San Fran maybe it worked in a vehicle made to run up and down one of the hills there like an incline railway.
Thanks for all the info guys still looking to find what it is. As for my rochester buying well i have about 4 chevy six intakes to be set up and a old 5 carb mcgurk for a gmc 302 so i need carbs but every year i tend to buy them cheap as they are great carbs.
Marine of unknown manufacturer. I'd look at old (wooden-hulled) speedboat websites to see what 6 cylinder engines ran in what classes back in the day.
Its off a 48 packard, a friend of mine once told me that if you can't tell what it is, it came off a "48 Packerd"
They were very old semis in a truck junkyard,,and Mack made Gas motors as did Cummins they have both been around since teh teens,,gezz
Cummins NEVER built a gasoline engine, at least not one that ever saw the light of day. Cummins is and always has been a manufacturer of Diesel engines. I am fully aware of the fact that Mack built gasoline engines for many years. All the famous chain drive Bulldogs were gas. You say you saw a Cummins gas engine, I raise the brown flag. You're going to need to post a picture. Post one of the Loch Ness monster while you're at it.
do and say whatever the f&^k you want just trying to help the guy out,,and I was referring to the manifold not the carbs,,as I saw something similair
You're not helping when you post bullshit. Show me ANY proof or evidence that Cummins ever built a gas engine and I will apologize. Cue the "Jeopardy" music now.
On a technicality, they do make gasoline engines. Onan makes their own gasoline engines and Cummins bought Onan, but like I said, it doesn't really count. It would be like saying Dodge makes diesel engines. They are making natural gas engines, but they probably bought out someone else's design. Cummins is around today because the founder believed in diesel power and nothing else.
