do u get a intake manifold that takes single SU'carb ?

Prob'ly need a custom made, but why fit a single SU? You will need a big one!

Its not a mini.

There are factory manifolds for duel SUs. but are hard to come by. I spose you could run a single but as Levey said you will need a custom manifold made and would have to run a 1 3/4" or 2" to match the original carbs performance i would imagine

Quote:You do if you want to screw an SU carb on one, but if you are asking if anybody makes one, then the answer is no, ... well not for a single SU & there's a good reason why.

A single SU manifold is a solution desperately looking for a problem, ..... & it's a problem that doesn't really exist in a commercial sense.

Why do you want to run a single SU carb on a small Datsun engine?
If it's for economy, then a bloody good tune up & the correct driving style will yeild wonderful results in a stock 1200.
If you are looking for a modest power improvement, then either a dual barrel downdraught Weber carb on the original manifold, or a fabricated adapter that connects the SU to an original manifold should do the trick very nicely.

thanx 4 the input guys . its jst an idea i had(1 too many beers)

I understand the beer bit!

Nothing wrong with a fertile mind
