Carb suggestion for a 512 with trickflow 270's

A Holley Sniper would solve a lot of problems but you would need to come up the learning curve on EFI. The Sniper is fairly easy to install and you'll get data logging as a bonus. If you want to stick with a carb then most any of the larger 4150 carbs should work. A 850 or 950 or even 1050 will work. The smaller ones will work better on the street while the bigger ones will make a little more power at the track. Personally I'd stay on the small size with the carb if this is your first engine build. The smaller carb has a better chance of working out of the box.

Yeah I was planning on sticking with a carb and neither my dad or I have messed with anything like the sniper. I've rebuilt carbs before and my dad knows everything about them too, we've been told by a few knowledgeable people that a 950 would be good and even trickflow said they test all of their heads with 950's. Then when we called holley they recommended a 750 and really threw us for a loop. The way everything is set up the car should have a stupid amount of low end power and the only problem with that is that I can only fit 235's in the back wheelwell... My theory with the carbs is that if I go too big I can always restrict it, if I go too small I cant do anything to make it put out any more. Does that make sense or do I have my head in the wrong place.
