My experience with full sized car engines would say not to use the high rpm cam. If you take a motor making low rpm power you would be better off to add to that power and set the buggy up to use it wisely. Tall tires would help in sand and help top speed. With a powerful low rpm motor, you would be able to turn them even in sand. If you use a high rpm cam on a motor making low rpm power, you lose some of what you have but don't have anything else on the top end to gain anything....end result a motor that does neither. With full sized cars, wanna be hot-rodders always slap a big cam in an average motor and it drives me nuts!!! Just my opinion, and I am new to small engine performance, so I could be wrong.
