art said:Not to thread jack, but isn't a 400 rod a couple thousanths shorter ctc than a typical sbc rod? (5.65 vs 5.7)
I agree with the recomondation of the SHP Dart block. From what I read in the new Car Craft, unless you do all your own machining, for the money, you would probably be better off with the SHP.
400 rods are 5.565" long. It's standard practice to install 5.700" or 6.000" rods with aftermarket pistons in a 400.
