Building a stroker, advice please

-
I went .040 over for a displacement of 418". Diamond forged pistons/ Eagle 7/16" I beam rods/Scat 4" forged crank/Childs and Albert rings and the usual oiling tricks w/8 qt. pan. The unusual route i went was that i used a set of Edelbrock magnums heads that were ported by Hughes Racing Engines along with Comp Cams roller valve train. I also went with an MP M1 Single plane with a highly modified TQ. Don't have a hp number on it but it's an awesome combo. Sure has lots of torque.

I should have a 4.125 4340 crank available soon from a very respectable source, it will use an I beam rod, dish CP piston and 1.2mm ring stack!
This coupled with some port work on your intake will make at least 550HP....at 10:1.

I've read up a little on the 4.125 stroke, not a lot of positive reviews as far as longevity.
