505" stroker

Started with blank Edelbrock Performer RPM heads.
Machining and porting was done by Hensley racing to their spec.
Head cc is 80.2 Don't have the flow numbers handy, but they breathe well.
I'm running 2" exhaust all the way starting at the headers.
Cam is Comp Cam and is a custom grind (Hensley Spec) but it's .576 lift in and .582 out.
Duration at .015 is .286 open and .292 close.
Duration at .050 is .248 in and .254 out.
