I've been running Holley 750's for three years now. My engine is a 427 side oiler stroker built by Bill Parham at Southern Automotive in Atlanta. I've also heard that this is too much CFM's but, you can't proof it by me. Unless you are under 2500 rpm's, it launches without hestitation. My understanding is that you must have vacumm assisted secondaries to eliminate lag. The 750's have that. I had dual 450's prior ( adifferent 427) and the hesitation was annoying. Bill's people know what thy're doing.
