1971 Match Race ~ 'Duster 340' vs. 'Boss 351 Mustang'

While I have never owned a 340 . I have had 3 Boss 351s and they were a blast when you were pushing them hard . However due to the large valves and massive intake runners the cylinder heads were better suited to racing than being used as a DD . If I remember correctly the Boss 351 was developed so it could be used in Nascar. If I had a Boss 351 today I would be shelving the Boss heads and replacing them with a set of Aussie cleveland heads .
