"As far as expensive, it's really not. His combo has been tuned through the years by trial and error" Yes very well tuned down to every detail, and awesome car in every aspect down to the paint and interior. The goal was to go fast with as many factory parts as possible in a low rpm "street" range and it does specatcularly.
I'll disagree on the expensive part-look at the total cost and TIME in swapping all the parts on a car or massaging them. Just paying yourself for the time much less the many parts, gaskets for making swaps is expensive. Track entry fees for test and tunes. I think at one time I heard there were well over 2500 passes on the car. Figure $20 a time entry at the track plus gas getting there. Yes the intake,heads may initially be cheaper but just add up freshening with good internal parts(valves,springs,guides), porting, etc, etc.
"Folks, running this quick just doesn't fall in your lap when you install a big high torque engine. It's about the combination of parts, the engine is simply part of a well thought out plan. Sometimes, as it did with us, it may take several years to figure out all the fine details to get everything working together for really quick runs......and did I mention parts breakage? To date we have broken EVERYTHING behind the engine, at least once!......Cliff"
Cliff has said it well, it's about the whole package. Cliff's car also recently went faster in the same rpm range with "bigger heads" (KRE vs 6X) so it's NOT JUST THE HEAD CC!!!(that dead horse Larry). If it were that simple Cliff's car would have lost bottom end and gone slower. If it was that easy where are all the 11 teen 3700lb cars in the staging lanes running cast iron intakes, Qjets and D port heads? Maybe a couple out there at the events that also get it done with all the right combination, but alot more in the 12s and 13s.
"If the velocity is too low the fuel falls out (condenses) into the runner and if the velocity is to low the cyl. isn't filled properly." If the velocity is too high the fuel also falls out and washes areas, what the wet flow bench "sees".
