Jeff Tuente wanted a new power plant for his 1970 GTO he is in the process of restoring.  Jeff stated he wanted a very reliable high horsepower pump gas combo for his GTO.  We used a 1970 GTO block as the foundation for this build as Jeff wanted to build a real street sleeper.  This is also the first set of Billet-TEK MAK design covers we machined!
