Got a eagle rotating assembly kit flat tops just under 10:1 , had my machinist verify clearences, balance, and assemble. Eagle Street Performance Rotating Assemblies B13402E040 - Free Shipping on Orders Over $99 at Summit Racing now this kit says "suitible for applications up to 500hp" and I dont think il be making no 500hp.. (anyone give me a hp estimate?)but what they dont set is a rpm guideline so that's one concern of mine especially with the cast crank and pistons so input there would be helpful, my hope is to have my combo make 400whp+ with minor changes.

Heads are a summit aluminum 64/200cc with 2.02/1.60 valves supposed to be a china cast brodix ik200, 258ish cfm .500-600 lift thats what iv read and was told by a summit rep plus I did a little cleanup.

Exhaust is 305 manifolds and joke piping used for a road trip, headers when the snow goes away...

Also engine is internally balanced but I'm using a large journal 327 balancer and 305 flywheel, is it neccecary to change these to neuturally balanced components? Hp estimate now? With headers? Possibly different intake? safe shift/max rpm? Is 400whp possible with my combo or with under 500 in parts?(not including exhaust)
sorry for my incredibly long post I tried to describe engine the best I could in hopes for an hp estimate and learning what is safe, thanks in advance to anyone who has a word of info to share
