yeah, most people dont go much over a 272 duration, most ive ever seen on a turbo drag car was 284. myself im going with 272 deg duration 9.5mm lift on my inline 6 turbo project. wasted spark is used alot on stock turbo engines with no issue, so as long as your camtiming and ignition timing are in check you should be fine.
