This might sound kind of strange to most of you but I've heard that Try-Y headers are easier to use when installing a Pontiac engine in a late 70's GM 4WD truck (clearance issue with front axle.) The 455/TH400 out of my daily driver car is probably an orphan now and would be real nice in my truck. If the 2nd gen F-body app is a style of header that is likely to fit such an application, and they can be coated in some way (or made out of rust-resistant alloy) to last in winter road salt, I might go for a set.
