'54-56 Twin H in a '49 262

Just wanted to educate myself on the possiblities of adding Twin H to my stock '49 262 engine. Is this a good/bad idea?



I've got a '54-56 Hornet Twin H intake manifold and WA1 carbs. This manifold has the 'buried' balance tube (I've read this was done to fit within the Nash engine bay). The carbs are the 'last' series I can find info on (2113)



I realize that my exhaust will have to be changed to either headers, or a '54-56 exhaust manifold, since the mating flange between intake/exhaust was changed, and is different than my '49 exhaust manifold.



I plan on installing jets and metering rods in the carbs that make the most sense for my application, and that gives me the best performance.



Just wanted to know the opinions of you Hudson people that have 'been there and done that', so to speak.



As always, thanks for the help.

Hi Doug,

I have a friend that has a 49 Commodore with a 262. He installed a twin H setup and he said it brought his engine to life. One of the resons, I suspect is better and more equal fuel distribution,giving more power,more evenly. I used headers on my 49 commodore and wouldn't think of running without them. It will deliver more power and most all,in my opinion, gets much more heat away from the engine compartment period. The stock cast units,well very well designed in its' day and being cast hold quote a bit of heat.It's like pouring a liquid into a funnel, the quicker exhast can be pushed out the quicker you go. I'd use the split headers and run duel exhaust to reduce back pressure. You would be amazed at power difference. Randy Maas has them,a little salty, but good investment for the long term performance and endurance of the 262. I bought my headers from Jack Clifford about a month before he passed on. They're a little "iffy" now. It took 6months to a $100.00 core deposit for a rebuilt oil pump. That's my opinion, hopes it helps.
