Twin H Conversion

[Deleted User]

Fellow Hudsonites,

Is it possible to retrofit a Twin H Set Up to a 262 motor in a 53 Super Wasp? If so, what would have to be considered to do this conversion? I am also thinking about hood clearance since the front is shorter on the car.

Glenn, I'm not an expert for sure but I think I remember that the 262 measures the same as the 308 so the twin H set up should work fine. I know people with more knowledge than me will give you the complete scoop on that set-up.

In '53 and '54, the 262 was available with Twin H-Power as an option. However, they use a smaller carb than is used on the 308's.

The Twin H-Power set up was offered as option on the 1953 Super Wasps (5C) as Option E for a grand total $80 and the Oil Bath Air Cleaners were an additional $14.68 (Option O).

the only problem you will have is that the rear air cleaner does not clear the wiper motor and must be pointed forward on the filter end. works but looks terrible, SBILL ALBRILGHT, L YOU WILL RUN A LITTLE RICH USING THE HORNET SETUP AS CARBS ARE DESIGNED TO FEED 308 INCHES NOT 262, yOU MIGHT TRADE THE NORNET MANIFOLD FOR THE 262 WHICH HAS THE SMALLLER BASE AND MOUNT STUDS TO MATCH, I HAVE THE STAINLESS HEAT SHIELDS AND DECALS IF YOU NEED THEM.

As Bill A stated, the factory option Twin H is different than the 308 Twin H. Smaller carburator with internal calibrations that result in a better fuel mixture for the smaller engine displacement. But when using the twin H in a short wheel base car stock rear air cleaner, both oil bath and paper filter will not clear the vacume wiper motor requiring the filter to be askew of the proper fit. The attached picture is of the modification that Paul S used when installing a twin H equipped 308 into his Pacemaker convertible. The factory also has a modification that is detailed in the mechanical proceedures manual that will move the vacume motor allowing the rear airfilter to fit correctly. Paul's modification allows the vacume motor to remain in the proper postiton and makes the filter fit appropriately.

I'm also in the process of putting together a Twin H set-up for my '49 narrow block 262. I'm just slowly restoring/modifying the parts I have, and may not even get it done until next year.



I have the longer wheelbase than the Wasp, so no worries about the air cleaner clearance, but I think the biggest obstacle in my case is the changes to the linkage from the gas pedal. The 308 has a linkage pivot point that I don't have, so I'll have to modify the stock brackets somehow. Also, it will move my coil, spark plug wire loom, etc. I also have a cruise control attachment that will have to be re-engineered.



Also, I believe with the 262, you probably want the smaller WA-1 used on the Pacemakers and Wasps. I just recently picked up two of the Carter 749s carbs that will hopefully be the right size for me. I was told the 2113s Hornet carbs I had would've been too rich without some tinkering.

We put twin h on Hudsonkid's 50 Commodore 262 and used the hornet twin carbs (WA1-968S?) and stock linkage that bolts on the head. Made up a bellcrank arm with three holes in it and welded it to the stock pivot mechanism on the drivers side of the block so it pulled down. A little adjustment (picked the best hole on the arm for travel) and syncing the carbs and doesn't seem to have any problems. The "kid" can probably remember more.

Could there be any pictures of this modification? I'd sure appreciate it.

When the "kid" reads this, he probably does. It was nothing fancy, I'm sure I didn't have more than 1/2 hour in it. He probably has a better memory also!

The Pacemaker 749s Will Be More Richer That The Stock Hornet Carbs As The 749 Was Used To Feed A 232 Engine, Two Of Them Will Give You Enough Fuel To Power A 464, Equal To Two 232s. Bill Albright

Does anyone have information on the vaccuum motor modification? I think I'd rather try that than do the air cleaner change, if it's not too intrusive.

What carbs should one run on a 262 Twin H set-up?

While we've found many sets of 968s and 2113s, I think in all our years of searching I've only seen one 990s for the smaller twin h. I'm guessing these are really tough to find. Hopefully if you find a manifold with the smaller base, it will have the carbs.

H-guy - Put the 308 TwinH on the 262. It will run fine. The acc.pump discharge might be a little rich, but you probably never notice the difference. Norm

Actually, I bought a complete 55-56 Twin H manifold with a pair of 2113 carbs. Problem is that the carbs turned out to be too far gone to rebuild, due to internal corrosion. So they're just a pile of parts now.



So I guess what I need are another pair of 2113s or 968s carbs. Maybe I can trade my pair of 749s with someone. They all have the larger base flange to match my manifold. I believe the 990s are the smaller size, anyway.

Hi Ken - must be a case of mistaken identity...isn't their another Dan on the forum that hosts his own website too? (Dan is such a common name )
