Speedmaster Rods, can i trust them?

Thats good to know, do you know roundabout what the engine put out?
nope.....have no access to dyno...and dont care what the dyno says cause they are usually inflated....but the 75 Duster ran 11.19 @ 118.56 in Vegas air.
Assuming 3300lbs with driver, Wallace says 465hp, at sea level. Probably closer to 500 to run that in lousy air, at altitude.
