I had thought that many of us had run this test over the years. laugh2 We frequently threw larger carbs on our Mopars. And with varying degrees of success due to a number of factors besides just the size of the carb.

But I firmly believe that most 440s would be quicker at the drag strip with carbs larger than 600cfm. Now, for street only we can talk about the smaller being better until you throw in the spreadbores like the Thermoquad. But overall, don't most here feel that any credible 440 with a tuned 750 would outrun one with a 500 or 600cfm carb?

Aren't there any youtube videos doing this kind of shootout? Or has everyone thought that this was settled (rightly or wrongly) in the 1970s?

Engine Masters episode 44 tested a mild 383 shivvy with a 600 and with a 750 carb. But I am not a subscriber. Can anyone link that test?

Here's Uncle Tony's take on this: www.youtube.com/watch?v=HdF7IAWFT8w
And he does make some good points on this subject.
