Briann,
I have other 6-7 more pics from other angles. Even some with them installed from the bottom that shows clearance around A-arms & starter. But I dont know how to post them. Thats why Larry posted these ones for me.

Formula8,
No pics yet, but they confirmed that they will fit 4-speed & there is enough room for Z-bar.

Lloyd-tx,
You got mail.

Thanks b-man, I tried to get them out as affordable as possible.

Briann,
I am running a 2 for one offer. If you pay twice as much for the first set, then I'll trough in the 2nd one of same or less value for no extra charge

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.

Since these headers only fit the second-gen 'birds, howz about:

'SCREAMING CHICKEN HEADERS'

2nd-gen enthusiasts (especially T/A owners) will 'get it'.

grandville455,
Heres some measurements I took today. for the distance from the front to the crossmember. I used a starting point at the center of the 1st bolt not the end of the flange. Just in case one flange had a little more meat than another. 1st the O-ports.
drivers side;
Distance back 10 3/4"
distance down 10 1/4"

Pass side;
Distance back 11 1/4"
distance down 10 1/4"

Now D-ports;
Driver side
Distance back 10 1/2"
distance down 10 1/4"

Pass side
Distance back 11 1/2"
distance down 10 1/4"

what would be involved in testing a set?

[Chewey]

Well, I got mine in last week (D ports on a 78 TA Auto) and finally got them installed. I ended up having to have an exhaust shop pull the motor to get the manifolds off because they were rusted so bad. The shop drilled and re-tapped 4 of the holes! Anyway, the shop did the ole sit them in the frame then put the motor in trick and they said it went very easy. Easier than most. Looking at the install I have only 1 minor problem and that is the brake lines are about 1/2" from the headers, which I think is probably too close, so I need to rebend the lines. There are absolutley no issues with the steering at all. I tried to take some pictures and have attached them, but they didn't come out very good. They stick below the frame less than an inch and the worst offender is plate I had welded to the collector as shown in the first pic. The second pic is of the driver's side with the front of the car at the top. You can see there's about 3/4" between the steering and the header. The pics didn't come out very well cause everything is painted black.

I also put the Pypes system on there. It worked well except for the placement of the chrome tips. The problem I have run into is that the tail pipes are too long and the tips are hitting on the rear spring hardware. I'm taking it back to the exhaust shop to weld everything cause I just don't like the clamps.

If I can get better pics of the install I'll post 'em.

T.P., how about the vulture wearing an indian headband with a couple feathers? Also, said vulture would have an arrow quiver (arrow holder for those archery-impaired) slung diagonally over it's torso.

Now, guess what's on the tip of those arrows that's peeking over it's shoulder? One or two should get the "point" across...

[prostreetpower]

hi, nice pics and sweet headers!
Just a newby question but is the tri y design suppose to be better than the four tube header design? Just wondering how these compare to the hooker super comps or dougs...500 sum thing are pretty expensive if u ask an 18 year old going to college and commuting on a 77 trans am with gas being $2.11.

P.S. Going to get a WFO asembly for my car..jst wondering what da shipping will be if shipped to Southern CAli..Thanks

Nice Lloyd, "Tribal tubes".......Love it.
