ok then i mis took the original post and im sorry...
well let me give you my thoughts in the gear thing....
if you drive around and most of your local speed limits are say 60-65... you obviously want to cruize at that speed...(unless your like me, a numbers chaser!)
now if the engine with that 230* duration cam is most efficent at lets say 2800rpm, then thats where the engine needs to be...
so now figure out what gear will allow you to go 60-65 at 2800-3K and i guaranty you your mileage will go up...
now i understand your thinking but revving the motor takes more gas... well that would be true if it was running less efficent than when the overlap and scavenging was sucking in extra fuel at the lower rpm than needed...
so what im saying is that good mileage doesn't equal low rpm's...
