Reply to "twin turbos"

There were very few twin turbo Panteras ever built; most during the late '70s- early '80s, due to smog laws etc. Almost none are still running, and none to my knowlege used Indy-car-style exhausts due maybe to the enormous heat-generating area of such pipes (even without the turbos, you need big heat shields). Stock Hall 180's probably wouldn't work, either- the collectors are way too far from the intakes, giving enormous turbo-lag in the equally long inlet pipes, plus the requirement for double-thick pipe flanges, stainless steel tubing, and the proximity of 20+-gallons of gas to the left-side exhausts. IMHO this is pure race-car stuff; if you pursue this, I suggest you not use a 351C block or heads, as they probably won't take the heat or horsepower for very long. OLd saying- 'experience with blowers comes with the number of engines you've blown... up! You might contact Dave Doddek (pantera@pobox.com) who built an injected 2-turbo Pantera in the Chicago area thats still running, albeit on its 4th or 5th 351C block. No 180s on it though.
