Updated pics on my big block A body

Are those Mazzolini headers (in the 68 not the gen 1 which does have interesting headers too)? Where does the collector end up and how did you rig up a muffler. Next time you get it up on a lift I would appreciate some shots of the exhaust from below.

Did you dyno the engine before installing it? What CFM are you going to end up with?

IMO that is a serious fish! Gonna be some pissed off rustang drivers in your local area.
