On my last FH powered deuce roadster I had the wide spread 2 carb Offy manifold with 2 94's. I had Baxter Ford in Lawrence KS set them up with a straight linkage and they worked great. I have no idea as to jet size as they took care of that.

Although not running a slingshot, I have been running a "Y" adapter on a stock manifold with a vintage speed progressive setup. No need to butcher a progressive 3-deuce setup - vintage speed has the two carb version.

Btw, the progressive setup has been on my car for almost 5 years and I have never touched them in all that time (save for removing the tumbleweed on my return from the LA Roadster show trip!) ...
I will never run 2 2s together again ....

have the same setup on my T-v8 , orig slngshot w/94's w/ progressive link. w/secondary carb, charlie price [vintage speed] set it up. haven't had it running yet .

Hey,
I cane across this while searching for information on this exact subject, running dual 94's on my 239 Flathead with a Sling Shot intake.

I am thinking that I would like a progressive linkage BUT want to retain the "ball" type factory linkage & use the stock type ends.

The distance, center to center is 5" on the nut. Does anyone know a good source or site that may offer this type set up?

Thank you,
Chris

Chris the progressive linkage idea on a two deuce set up needs a secondary carb designed for that purpose. That adds to the cost of the set up. I have tuned dozens of two deuce assembly's on flatheads everyone with both carbs working together. Its easy to tune the pair of linked carbs using a unisyn gauge and a vacuum gauge. The engines run excellent and pull nicely the two deuce assembly's were originally designed to work linked together not progressive.

Chris,

I’ve been running my slingshot manifold with a straight linkage for the past five years since I started this thread. Initially I had some issues setting it up the carbs, but found it was mostly my inexperience was at fault. Since the original setup, I have had no issues running the duals with the straight linkage. I did have to make some distributor adjustments and it took me a little time to find the right balance. The car runs very well on straight linkage and I found the car to have a little more pep in acceleration. My original thought was to try both setups. To see what worked better, but found that the straight linkage worked so well, I never went through the cost and effort to try the progressive linkage. If you do let us know how it works?

Regards
