[QUOTE="Garbage_Mechanic, post: 1544301, member: 1610"] Back in the apex of 7.3 development Swamps did a dyno mule engine build where they actually did it the right way.... they made changes one at a time and dyno’d the results. Some changes they also tested NA and turbocharged. Every turbo engine is NA once per acceleration cycle (or multiple for stick shift). The results of porting were definitely worthwhile and showed up both NA and turbo. Been years but I recall 50 hp at lower rpm. Overall more efficient with no down side. Old timers such as Charles and hotrodtractor will remember this. [/QUOTE]
