BMBBR5 Roller Cam 283 on a 115


Thanks for the cam card.
Comparing it to your 3R cam I bought (used) it is 4 degrees longer duration, 3 degrees wider LSA, and the same lobe lift. That is in line with going from a 540 to 572 with your builds. And with that user's 1.6 ratio it comes out to .754/.722 valve lift.
