272 and 280 sound very long duration for turbo cams!
what rpm do you expect to stop blowing the intake charge out through the open exhaust valve?
for NA, those cams would kick in around 4000+?, with turbo, how much higher does it go before your cams are efficient?.. or is it all in the lobe centreing?

Hey Stewart
Yes, they are large cams for a forced induction motor, but I'm happy to experiment with my adjustable cam gears to change the lobe centres & see what we can do. Its all about experimentation....... we'll see how it goes. Maybe the cams will be for sale for a naturally aspirated screamer if it doesn't work out! Although the advertised duration is 280, the duration at 50 thou is actually very close to the HKS 272's, which have been proven to work well in many turbo applications. with 110/110 phase, the overlap at 50 thou is zero degrees.
Cheers 
Phil
