"In modern NHRA STOCK CLASS, 302 & 305 Heads are so exotic that the valves are relocated, cantilevered and the heads cut in 1/4's , relocated & raised ports, rewelded etc, etc, etc......its common to have $18 - $ 22,000 + in heads and intake work."

This is not correct information. Eric you are right 373 crank shaft HP does deliver this type of performance at Wades given weight. Its absurd to believe any one has any reason to mislead HP figures on this car. The 305 stocker BTW is a stronger package by far than the 283 combination. Stocker heads have non of these above modifications. Its all about making your power at a higher RPM then being able to carry the power, then theres the rolling car which sets some people apart from the rest.
