Hello Z Kid. The mystery carbs wont bolt onto the standard N36 manifold as there are three mounting holes in the carb and 4 on the standard manifold. I dont think they are British as they have ASIAN ISO in the casting on the side. Thanks Simon

Ive posted more photos and are awaiting approval. Its beginning to look like the boats going to be sercure with two sets of anchors!! Thats very much for your help. Regards Simon

They measure 3 1/4 Inches. thanks

Photo as promised. Thanks Simon

Why does blocking off the water to the manifold and carbs make them car go better?

I have a 1976 Dastun 260Z 2+2. It has the original 260Z flat top carbs ( Boat anchors)and N36 manifolds with four bolt carb holes. Recently while in Australia I picked up a set of carbs, aircleaner and manifold as well as an unused manifold that some Dude that reckoned the were off a 240z that he crashed 20 yrs earlier. The manifold is a webed design that look like they are off a crossflow head. They do not have space for exaust ports. The numbers on them are 41025 and the unused one is 41026.The SU looking carbs have 1G26 and Asian ISO stamped on them. Hopefully this will mean something to somebody. So what I want to no is which manifold number do I need to get hold of to bolt the three hole carbs to my head (Engines) I have tried the search function and have learnt plenty, but hasnt been able to help. Any assistance would be appreciated. I can post photo's tomorrow if that helps. Thanks Simon
