It is the question of the unknown. Here I am with my ERA cobra that I have been happy with for 21 years. But, since I have a pair of 390's and the original cars had a pair of bigger carburetors, I wonder what the difference would be if I changed from 390's to 600's. It is an academic question, and if someone tells me that using 600's would be far more satisfactory as a daily driver, I might be inclined to make the change. The subject of progressive linkage entered this question from left field, but it is there and it is a valid consideration. So I am not saying that I am unhappy with the 390's, but I am curious about what it would be like with 600's (probably with progressive linkage). Thanks for your questions, but this is an interesting learning experience for me.
