What kind of throttle response & street manners will a big intake runner have? As much as I want to have quick times at the track I do putt around town to car shows and cruise nights where the motor is rarely much over the stall of the torque convertor. Is a 850 cfm single 4bbl sufficient to supply fuel? I have a Holley black (150gph I believe)electric fuel pump and regulator that I hope I can reuse. I have been watching some sets of Dart Pro One aluminums 345cc with 2.30 intake valves for $2000 delivered. When I contact the sellers the usual upgrade charge for springs able to handle up to .700 lift roller cam is $150. I don't mind spending a few extra bucks as long as the payoff is worth it. I've had luck selling some car extras here on RJ so now is the time to "re-invest" in my money pit. For comparison sake, what does a set of as cast pro 1 345s flow and how would the difference realistically make on my motor?
