Low Deck 400 Builds

I have a 400 (actually 406) that I don't need anymore. The block is 4.375 and it has a forged 383 crank in it. This was a running engine with high compression pistons that ran high 10's in a street car. I'm going to switch over to a 470 engine with pump gas compression so I don't need the crank or the block anymore. Only problem with the block is that it has to use external oiling since the internal pickup was plugged. I'm switching over to internal oiling so I need to machine up a new block. The 406 ran strong. With ported RPM heads and a small roller cam it made about 575 hp. The guy drove his car to the track, ran 10's and drove it home.
