Camshafts used in the motion 427's

[427TJ]

What's the difference between the old Walker turbo muffler and the current Summit turbo? Just curious.

I'll tell my buddy that his 20+ year-old turbos are valuable and to keep them if he ever updates his Camaro's exhaust. He hasn't turned a wrench on it in any significant way since the LS7 went in in 1988 so my guess is that those turbos will still be under the car in 20 more years...
