Should go real good. Had a slant with 1/34 triple s.u's that went real hard.

Another AP5 valiant still going strong.

I have only seen others run those. Should work really well. They are best for broad range HP as well as peak HP for a carbureted system.

My Dad seems to think it would be a real pain in the ass to tune. Do you think that would be the case??

With scroll type black meter device not the red ball flow meter. And bunch of jets (start with red box of jets). Start with idle jets to get idle mixture in ballpark and balance them with good flow meter. Then main jets to get it right at beginning of throttle progression when progression holes is past.

Then air jets for mid to top end range (RPM).

Not too bad at all.

Requires distributor without vacuum.

Linkages is critical that all throttle opens at same time by carefully checking them and alignment. These carb is balanced via bypass air needle screws not by throttle.

From my personal experience, getting them tuned and in-sync is a PITA for a novice. (I used a red ball flow meter. ) I had a spitfire with dual DCOEs. Even after professional adjusting, they wouldn't stay in sync very long. It wouldn't be my first choice, especially for a daily driver.

A few years ago I pimped out a 73 Toyota Corolla. I managed to find a Japanese 2TG DOHC and put dual side-draft 44 Dellorto's on it. Too tune them was not too bad. I used a piece of fuel line to my ear to "listen" to the air flow into the carb throat and got it pretty close. I had a friend tune them professionally and they ran AMAZING. Incredible throttle response and pulled hard all the way up to 7000RPM.
I didn't want to have to re-tune them so I put a drop of superglue on each of the adjusting screws. lol
Might not be the best way to keep a carb in tune but it worked like a charm no matter how hard I ran those things.


-EDIT- I just realized that nobody has posted on this thread in 6 months. lol A little late to this one I guess.

Ditto on the hissing tube to ear method. That is how I would synchronize two SU’s on my 59 Austin Healey Sprite. Those things would stay balanced for about two weeks…
