June 2012 Chevelle Update: Firewall, Engine Placement, and Race Car A-Pillars!

Long story short, since my last update quite a bit has happened by Jeff Allison at Allison Customs from a work and decision making perspective that will dictate the remainder of the build. First and foremost, the location of the LS engine has been determined. As anyone can attest to, when placing a new generation engine into an old car the easiest route to go would simply be to place the new engine where the old one used to be....but what fun would that be? Since the car was already in a bazillion pieces we decided to take the opportunity to improve the handling of it even more and relocated the engine as low and as far back as was reasonably allowable (that didn't require the engine in the front seat with me).
