Hello 8th Gen Community! We were just supplied a link to this thread by Jonathan Donner of APD Motorsports... he apparently used it to compare camshafts. Ultimately he chose BluePrint Stage 2's and asked me to confirm the spec's that were posted, so he could finish the outline for an upcoming MotoIQ Feature. The data listed is dated... but its a good idea that it stay up but we would like to take the opportunity to inform you all that BP released revised "Billet" camshafts (Stage 2 and 3) earlier this year. It would be great if this info could be added to the first post.
