I could use a little help finding a good stroker kit for a 440.I'm no pro racer,but still would like to go just a little faster...I'm running a 60 over 440, with a factory steel crank and 6pack rod on TRWflat tap pistons.It only runs in the mid 10's...I'm thnking about a 500in.motor????The top end is a set of RPM's that were port@polished by MODERN cylinder heads.I'm running a comp cam(673lift) and roller rockers(gold,6.1's)With a 950HP holley(with some work done to it)...
