Wasn't sure if the high domes were stock, couldn't recall as it's been decades since I had a 160 or 175 apart. MegaCycle pretty much does all cams so that's no surprise - and I have a set in my bike too. Is the power peak around 11,000 to 11,500? My Dad and I built a 175 drag bike with the MegaCycle 122-20 grind IIRC (it was 45 years ago) and you could shift at 11,500 on it, pulling strong, but it also had Powroll 200cc pistons in it too, can't recall the CRStock second over pistons. Megacycle cam.
