Alex,
It should be good for 145-150. Gas flowed head and 285 dwell ultimate road cam. Engine should be OK to just over 7,000 have fitted arp bolts to the big ends, I need to check the actual limit. It's a piper cam, to be honest I would have preferred a QED cam but the guy who did my head sourced piper as he preferred them. Piper were not particularly helpful on jetting or any advice. We will see how it works out when it's complete. Looking at led headlamps etc to reduce the load, I expect the alternator should kick out enough at low speed.
