M8 128 w/ Andrews 554 cam.
By Thom. on Verified Purchaser
I did a M8 128 build and used this camshaft from Andrews. It simply performs amazingly. Need to upgrade to high-lift valve springs, but this job was easy. Several dynos and tuners use this cam and the torque is flat-lined around 160 and hp around 145. My 2018 Fatboy is now an amazing machine to ride. M8 128 with Andrews 554 cam and 2 into-1 exhaust, new lifters and adjustable pushrods, A/C, and new clutch springs.
