I consider that a problem and a restriction Rusty having 3 in of vacuum at wfo.............less power potential no matter what "charts" or theories say and the ONLY way to know for sure is to try a bigger carb. I love it when people say "But on the DYNO it did this or that and the Dommy only made 7 hp more than an 850......lmao.....EVERY time I put bigger carbs on MOST motors they go faster.....WAY faster in some cases like Jeff Sausier, from 10.60's to 9.90's w/a Dommy I did, then there's the pump gas 3430 lb Chevelle that went from low 9's w/an 1150 before I modded it to 8.90's then a best of 8.84 at 150+ w/a 1250 I did............Real world testing, not dyno mumbo jumbo......
