Here's an interesting one; built in Berkeley California by the people who designed the Liberty aircraft engine in WWI and helped Duesenburg and Miller with cam design.
Overhead cam, dual ignition, about 250 HP but about 550 ft lbs of torque. Pretty cheap by the pound!http://cgi.ebay.com/ebaymotors/1958-HALL-SCOTT-ENGINE-COMPLETE-MOD-6156-FE-AS-IS-COND_W0QQitemZ330266680473QQcmdZViewItem?hash=item330266680473&_trkparms=39%3A1%7C65%3A1%7C240%3A1318&_trksid=p4506.c0.m245
