Hay guys. I have a 69 Chevelle with a 400 small block. It works great. It makes 508hp and 524 lbl tq. I am looking at a CNC Motorsports 434 short block to put all my good parts on. I have a Shafiroff 582 that works verry verry good in a difrent car, but this one is a lower buget deal. Has anybody ever used any thing from CNC motorsports, or have a better sugestion. There prices look real good. And it is all brand name stuff. Dart SHP block, Eagle crank and rods, Mahle pistons. All for about $3,400. Any help would be apreciated.
