I agree with Unit on the statement that your engine components are mismatched horribly. It's best to stick with parts that are made to work well with eachother.
On the whole carb vs. efi thing, they both have their advantages and disadvantages. EFI is way more expensive and just kind of a pain sometimes because it's all computerized and you can't do everything the old fashioned way. With a carb, pinpointing the problem is way easier than with computers.
I run a 750 Edelbrock carb with RPM intake and RPM cam, stock heads, 3:1 gears, and it bogs, but not horribly after I've learned how to control my engine a little more. And it pulls harder than crap on the top end squirting 750 cfm into the intake! If I'd get rid of my stupid a$$ stock heads and run some 3.70s I'd be mid-13s with a 3200-3300 lb., 32 year old car with a sh!tty suspension! Man...I can't wait until I get some $$$!
