(2)450 DP's vs (2)750 DP's

I was always told the twin 450’s for milder street applications.
I’ve road in. 440 Charger with twin tunnel ram 450. I thought it was pretty darn good.

Likewise, twin 750’s for racing, unless it’s a super beast. Back then, a good 30 years ago, I couldn’t understand how a regular 440 could be happy with 1500 cfm worth of carb. It’s a good bit to fully make use of. But I didn’t know anything of this arena and of performance.
