This is one of glenn halls old race motors . It's a full race d&d 1004 triple with stock stroke zrt 800/tcat 900 crank and triple exaust ports/f5 cylinders boost ports and full race domes and runs on c16 race fuel . This motor made 258 hp on d&d dyno and 126.5 hp on d&d/glenn's track dyno . This is the only one that d&d made like this . D&d only made one of these motors because they went to the stroker motors because the stroker made like 5 more hp . This is a complete setup with pipes and 1993 tcat ingnition . Motor was just freshened up and has 2 runs on it since . Email me at wood@cheqnet.net for more info
