The 4-7 swap cam is very popular with our customers and we have supplied them with engines shipped not only here in USA but also to Australia, New Zealand, FInland, DenmaRK, iSRAEL, and other counties around the world except for Africa( we don't have any customers there at this time)((mostly because of the scam deals from there))

The dirt track racers love them as the different power off the corners is very noticeable and they still run up top---Many companies besides Lunati have them
