That depends on the RPM range you intend to drive it in most often. Likely plenty until you get into upper rpm. If most of your driving will be under 5K, then it would have better throttle response with the smaller primaries. just my 2¢
Combo is a clone of one by IQ52 here. Cam is designed for 1800-6500 range. Most of the driving will be cruising for now until she’s well broken in. Durability has been a prime focus in this build too. Hopefully that works out.
