I doubt it would be much. I have only seen one in my life and that was 35 years ago. My uncle had one on his 23 T with a 396. He said it worked ok but he eventually went with a 4 bbl Holley that worked better. The 3 barrel holley seemed to be one of those "why not" experiments. My take is if it had actually been a good idea, Holley would still be making them.
They put them on the Baldwin Motion Chevy's in the late 60's early 70's. They had them running like the wind !!
my dad has one that he ran back in the mid 70's. The spec sheet has it at 870cfm. He said it worked well on the tilt nose 48 Chevy with a big block.
Yes they do still exist . I have both the 950 and 1050 cfm models and always looking for more. As for value, they are worth as much as someone is willing to pay....but do not pay more than you would for a similar, and new, 4-bbl.
I think they were Holley's temporary fix for a growing need for more CFM, and were dropped when the new line of Dominators came out for the "huge" market. I think it would be worth a lot just to be able to watch people's faces when you say "I'm runnin' a three--barrel Holley."
I have been running one on a 68 Camaro with a 427 for about 3 years. It was easy to overhaul and works great. It kicks in like a good working quadrajet. I think it was about $100 at a swapmeet. I would certainly buy another one.
i've seen them go for what i think is stupid money on ebay , i saw a nice one go for $600 i have a edelbrock C3B too
All depends on which one you have. The straight leg booster are on the 1050's and the round leg boosters are on the 950's. both are desirable but I have been told a complete 1050 cfm with matching parts is the one that will bring the large dollars. The muscle guys from the mid 60's seem like the cats that want these. We ran one of these on a dirt car with a tunnel ram back in the 70's and it went real well. Check out some of the carb retoration places for the pricing>>>>.
I think it would be more fun to tell em you got a 6 pack " Hows that 3-2 barrels?? Nope 2-3 barrels!!" Watch em scratch the head and walk away>>>>.
I think a little research will show that they were used/experimented with on NASCAR long tracks when they first came out. I've got one that I've had for over 30 years. I tried it on a big block Camaro before I went to the tunnel ram I ended up using on my B/MP. I always wondered how it would work on a street driven car but never took the time to try it. Frank
Dale Wilch has what looks like a NOS or restored one of the 1050s for sale. If you click on the carb it will show the oval secondary. I have seen more on shelves than on cars, probably more than most street cars could handle at the time. http://marketplaceadvisor.channelad...tail.aspx?sid=1&sfid=78392&c=613655&i=9738709
I bought one brand new at super-shops back about 1988. 950 cfm, $349. It worked quite well on my 550 cid [bored and stroked] cadillac installed in a 70 skylark. Throttle responce was much improved over the 750 holly 4V, and with the 3V it finally got the front wheels off the ground. Street performance was nice, and I believe mileage actually improved... Probably because I was easier on the throttle. When the secondary kicked in, it was quite a ride!
