600 CFM vs 750 CFM...

That was my 1st thought. But I was curious
about the overall effects. And throttle stopping would leave you with all the negatives of a large carb and none of the benefits.

I've yet to find the negatives of a larger carb on a mopar. Albeit I only run holley's but I always run a 750 on my SB's and my BB went from a 750 to an 850 to a 950 and loved each bump. It suffered no negatives. No on a BB chevy I have seen negatives from a larger carb, even when tuned properly. According to my engine builder it has to do with the heads.
