360 block limits

One of the fastest street cars we have around here (and the guy drives the wheels off it on the street) is a 7 second camaro with a 540, turbo and a throttle body. He sent the specs to a place out to a tuner in some other state and they spec'd a tune for him and that's what he uses. I will not change any of your minds and I really don't care to, I like efi a lot but I also don't sugarcoat it into being gods gift to the performance world. Like this thread I'm burned out, back to the regular program.
Some guys tune their own and some don't. Just like some build their own engines and some don't. Some also rely on the engine builder or someone he trusts to modify the tune.
I know people who purchase tricked out carbs, and won't hardly change a thing till they run it past the carb builder.
