Hello together, Since I am still a blancher newbie in the field of carburettor world, I hope that there are some of you who can help me further: I have to clean the present carburettor, a Holley, and I have now heard of some that it should be more advantageous to get a noblebrock or something like that. However, none of the “experts” could tell me what the advantage/disadvantage of a noblebrock should be and whether it would really be worthwhile. o where does a noble brock differ from an original Holley? Supposedly, the engines should run more efficiently? Can I hardly imagine. That would also apply to a Holley, if it is set correctly, wouldn’t it? Can you help me further there? And how can I find out which carburetor type is installed with me? Questions about questions… Motor is a 66er 429cui.
