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
A 2013 BOSS 302 was Dynoed at 380 RWHP and 347 TQ
the same day.
New Mufflers and pipes
New Spintech Super Pro Street 9000's and new pipes from the collectors back
with an H pipe, all 2 1/2". Thought about getting an X pipe but the
mechanic said it is hard to fit em in early Mustangs and thought the H pipe would
sound much better
