Ok so sounds like hydraulic is the way to go. Ill try to call Bullet and get some info from them. I imagine that their prices are more since its more custom? Beyond that whats the benefits of flat tappet vs rollers?
If you are all mechanically inclined, I'd go solid flat tappet over hydraulic. I just had Bullet grind me a custom solid flat tappet cam a month back, I belive it was $275.
