i understand what youre wanting and trying to accomplish, i wont go in to detail but i will say as long as the valvetrain is as light as possible you would beable to spin the rpms up, i myself is building a 410 with a lunati pro series crank and rods and the lightess pistons found, with this in mind the topend has to match, light weight everything valves, rockers, springs, locks ( everything )


bottom line, its not cheap when you start hitting 8k rpms or above
