Re: what might have been for '92 heritage edition

There are a number of post on the runners. They were one off (or maybe 2-3 sets) made. Not production castings, but fabbed up. So yes hand made for the prototype. Headers were SLP if I recall ... but due to the Aluminum vette heads, they may have been unique as well.

Headers were unique ... angle plug heads.

Re: what might have been for '92 heritage edition

Maybe my memory is a little fogged from old age, but aren't those headers similar to ones you'd use on an lt1 fourth gen? Btw, I'm old enough to remember reading the magazine article on that car. Wonder if it's still in my dad's basement somewhere...
