My s/strip '71 340 Cuda with a 750DP, .484/284 hyd. cam ran well, put an 850DP on it picked up almost 2/10ths. Same carb on my stock all iron 440 with a big sft cam made 530fwhp on track, ran perfect on both my motors. Its the carb itself, set them up well and they'll run hard on anything. You should never lose time with a larger carb if you've got a perf combo on a mopar.

We ran/run an old 950HP (830cfm) on my mates mild 10:1 589ci wedge motor through muffs on track, (showed 2" hg@6000rpm on dyno so restrictive), but it runs real good and only drops around 20>25hp from the dyno numbers worked on weight/mph. They tried a 1050 Dom on the dyno and it made 1hp more, carb not set up or rubbish.
