I totally disagree with the 750 being to big, back in my time you could buy two 4 barrel setups straight from Ford for use on a 289 ... The most potent per cubic inch car I ever owned was a 406 with a Ford Factory 3 2bbl setup (950cfm), and I was personally involved with a 427 cammer that ran right at the NHRA national record with 2 dominators, thats 2300 cfm. So if a 750 is waaaay to big for a modified 351, then none of the three motors I just mentioned should have even run.

I'm not saying the 600 won't work, but i still think if you get that thing running like its capable of, then way out on the top end you're going to be approaching the edge of the envelope for a 600, you aren't going to get the top end push from a 600 that you would from a 750, with your combo.

Bottom line IMHO the size of that carburetor isn't what is keeping you out of the 12's, you should be able to get there with either of your carbs.

Keep tuning man, you'll get there

PS: as to that vac port, if you don't need it, plug it.
