auburnseeker 4,531 Posted June 11, 2020 Share Posted June 11, 2020 My 47 Hudson Pickup had it on it when I bought it. Has a 49 engine and a 54 Twin H setup I believe from the casting numbers. I rebuilt the carbs and it runs great. Can't see any negative to it once you dial it in. It runs well and has great power. If you are looking to buy an intake/exhaust manifold, I do know you have to watch to make sure it's not cracked. Link to post Share on other sites
StillOutThere 149 Posted June 15, 2020 Share Posted June 15, 2020 As with any multiple carburetion, you MUST balance the carbs. Owning a "Uni-Sync" balancer is important. All good after that. Link to post Share on other sites
Bud Tierney 111 Posted June 20, 2020 Share Posted June 20, 2020 It's been tears ago, but my brother ran Hudsons for several of their last years production, to 1954, , always buying all the power he could incl Twin-H...Seven-X engine sound familiar??...anyway, a performane lover, drove fast and hard (Texas/NM), the only complaint i remember being that the U-joints couldn't handle the power, so the Twins must've been fine.

paulrhd29nz 79 Posted June 23, 2020 Share Posted June 23, 2020 There is not thing negative about a twin -H setup. They need to be dialled in just like any other multi carb set up. I get 18 mpg all day long. A blast to drive. Link to post Share on other sites
carbking 1,219 Posted June 23, 2020 Share Posted June 23, 2020 (edited) Carter WA-1 carburetors. Leather accelerator pumps, so ethanol contaminated fuel doesn't hurt the pump. Excellent carbs. If you are buying a set or piecing together a set, be aware they were used on three different size engines, so there are different sized carbs. The ones for the 308 are the most difficult to find, and the most expensive. As others have said, they MUST be synchronized, but that is an easy procedure; and once synchronized, just leave them alone. Quality set-up. Jon.

Actually, the U-Joints are pretty standard fare. For example, the ones in his Hudsons were the same as Chevrolets. The weakness was in the driveshaft center bearing supports. A little too much torque and they would tear loose and leaved the driveshaft to wobble and send odd vibrations throughout the car. Link to post Share on other sites
