1970 Mustang BOSS 302 On the Dyno
This 1970 BOSS 302 came out of a barn recently and made 257 RWHP. The AF ratio was way off as can be seen by all the black smoke. The 257 HP number was made after some tuning. I think it made something like 230 HP in the video. A 2013 BOSS 302 was Dynoed at 380 RWHP and 347 TQ the same day.
