Re: Tri-Y headers: Doug's, Stan's, Thorley, or??

click HERE for a vid of my Thorley triY's into an open Y pipe.
They interfered with my clutch, co I used some Hookers instead.
EDIT; mine were from a squarebody, not sure about the difference.

Nice! -- Yeah, the instructions say some z-bar modification may need to be made, but I've already moved mine back about 1", so if I have to do a little more tweaking, I'm not too concerned.

Dougs and Thorleys are essentially the same headers.. and Stans are "copies" of older Doug Thorleys.. I have had Doug Thorleys on my 68 for over 20 years, mime are "the hard chrome" nickel coating and even though it is showing its age they are still in good shape.. I have had nickel coated big tube Stans on my Big block Suburban for at least 12 years and they too are still in good shape.. IMHO all are comparable so I would go with which ever ones you take a liking too.
