yup! like i said... i beat on it for 8 years before the turbo went on it then it took another 2 years to break it! i have them im a w2 headed 416 that i built for a buddy of mine. the engine in his 71 dart. beats the hell out of it, drives it to the track runs low 11's (it would be in the high 10's with caltracs) and drives it home..
