What size valve springs? I have a 427 with a 82 mm turbo. Just had the car dynoed and it wouldnt make more than 867 on the dyno. The cam is 253/259 duration on 114 with 612 lift I think. I had this cam and used it I know it's ot the best. I think the springs are 125 and 295. Do think hey are big enough. Oh and it is a hydrolic roller. What should these be at

That doesn't sound like enough spring pressure to do what you're trying to do.
Check out the Platinum springs I sell, 155 lbs on the seat and 400 lbs @ .650" lift, they work great with boost because they have good seat pressure but not too much open pressure. http://www.briantooleyracing.com/660...s-engines.html
