Came into possession of a set of twin su carbs tags on them are AUC 784r and AUC 784F, question is can I obtain a manifold to fit these to my mini? Currently set up on mine is a hiff44 with stage 1 kit fitted on a 1991 cooper any help will be great

AUC 784 comes back as an H4 build for an MGA! You could probably sell them to an MGA owner and easily make enough to buy a set more suited to the Mini outright. There are manifolds still available for H4s I believe but these are a rarely used thing on a Mini. They were used by the works teams. If I'm not mistaken in an MGA they would be set dead horizontal but in a Mini would need to be at the same 30 degrees as an HS. Unfortunately changing an H type over to Mini spec is far more expensive than changing an HS. The float bowls alone are £80.00 each, unless they are the thermostatic type which are even more. Then there are jets and linkages and it's all pricey stuff. To give you some idea, a brand new set of H4s built for a later Mini Cooper, fully manifolded up and ready to fit will cost you more or less £1000.00 from SU, while a set of HS4s in the same state will cost half that.

Ah right, the kit I have has linkages and gaskets they are brand new in boxes, what price would you say I could get for them ?

[Dan]

Brand new? Where on earth from? Have a look at the MG Owners Club websites to get an idea of prices, they have all their catalogues online.

Been in my dads workshop for god knows how long all boxed and sealed and ok will do

If they are the type im thinking if i got myself a manifold that allows fitment to a mini. Are they hif38 lookalikes ? Only problem im having is getting the linkages to fit the ones i got where way to long so ive been trying to make my own but it is a little tough

Im looking into selling them atm and yh looks like hiff38 just looking up prices on what these sell at
