What determines the powerband of an engine via intake manifold design (Carb v. LS6) I thought I would post in here instead of the advanced forum because it's more of a general question.
What benefits, if any would there be to a carb style intake manifold with a 90mm elbow and throttle body with a single pattern cam, 224/224 .581/.581
vs
an LS6 intake with a 228/224 .588/.581.
the only people I see using the carb style intake are pure race cars with a T-Rex, stokers, and FI guys. Can they be made to be streetable with a small cam? I might be a little too outside the box on this one, but it's not a lot more expensive than an LS6 intake (damn not having an 01 car) and I'd get a lot of attention when I pop the hood.
Thanks in advance

I'm fairly certain that the MSD box is only for if you want to run a carb, I would use the Edelbrock intake with injector bungs welded in out of the box.

does any one know what the internal dimensions of the runners are in either manifold? Maybe the carb has much larger runners, reducing port velocity and robbing you of low end torque which is why only 8,000 rpm 346, strokers and FI guys use them?
that was a pure guess so maybe some one else can fill me in on some of the details, I know a sheet metal intake or a custom made ITB manifold would be best but I'm in the $400 range not the $4000 range.
