[johnnieg]

How much does the stock TBI flow? Can anybody reccomend any upgraded setup? I plan on geting vortec heads and TBI manifold. /forums/images/graemlins/k5.gif

A stock SBC TBI flows around 450 CFM, while a stock BBC flows around 670 CFM.

A holley can flow 670 cfm. It may require some chip tuning to take advantage of it though.
