No apology necessary, I agree a lot of smaller cubed engines came with and/or use larger carbs. There are a lot of 355s making big power running at high rpm and sucking down every cubic foot of air the carb will give it. It's not just dependant on cubic inches but valve train, induction, rpm, etc. You missed the word "if", I said IF you are over carbed with a 670 you will be over carbed with a 750 or 800. I do not think MJ69 is over carbed with the 670 Holley. The Holley is a good carburetor, I belive he/she will get it, and the rest of the engine, tuned and running the way he/she likes. I was stressing often the carb is blamed for problems when it may another component or system that is at fault. But there are some who have the bigger is better mentality when bigger isn't always better. A 1050 dominator sitting atop a big honk'n single plane intake on an 8800rpm big cammed engine is great, not so much for a small cubed small cammed runabout. Once again, just my opinion.
