small block 400

If your'e going to bore it, make sure it is honed with deck plates. This will insure a round hole after the heads are torqued. I believe this is especially important on the 400's because of the thin walls. As 406 Q-ship said, use the longer 5.7 rods. I have been running the 400's for over 15 years with no overheating problems. I also don't run them with the steam holes.I have the steam holes plugged, and deck the block to eliminate them, and I know alot of people say you need them, but I have had no issues. I would read up on different 400 builds, and combo's, before you start buying a bunch of parts. I would also consider what you want the engine to do and contact the cam manufacturer of your choice to get a recommended cam. I've had alot of luck going this route. Good luck on your build, and you will be smiling from ear to ear the first time you hammer the throttle! I promise!
