Looking to Build a stroked 400. When building a 417 of 21 combination can a stock block be used and does it have to be clearanced for the increased stroke.

It will have to be clearanced, but how much will determine what kind of rods you have. H-Beam rods are a little more bulky and will require more work, while I-Beams are not quite as thick and lighter. There are some really good I-Beams on the market now.

You will have the most problems with cam/rod clearance. You can either remove material from the top of the rod/rod bolt on the cam side or you can buy a small base circle cam (or buy an expensive rod for a stroker application). You may have to remove a small amount of material from the pan rail area for the rod nuts to clear. Just take a little more from the notches already there - don't get carried away - you may strike water!! Good luck!
