I would call delta cams in Tacoma washington and tell them you want a hydraulic cam with a 268 comp intake lobe, a 280 comp exhaust lobe, ground on a 114, with 4 deg of advance. That would probably be inexpensive and run well with a small blower on a mild engine. Aren't you trying to put an M90 on a 250?
