Ford Powertrain Applications has headers for your 75 Thunderbird. They are quality headers. fordpowertrain.com
Thanks very much for the link, sent them an email asking for some more details on their products. The Hooker headers are 1 7/8 primary with 3" collectors, and I've always been a fan of Hooker product quality, but I also would rather buy a product made for my car by folks who's sole purpose is building parts for the BBF cars and old Fords. Plus as a small business owner I like supporting other small businesses.
All good thoughts to consider. A little about me, I've been building cars since I was 15, mostly Fox bodies of one sort or another, everything from daily drivers to 10 second street cars. At one point I was a fabricator for a local shop building suspension and chasis parts, though these days I'm just a keyboard warrior for Intel, lol.
I bought the T-Bird because I was on a quest to find a BBF project, and though the T-Bird wasn't my first choice this particular car is a survivor and I felt it worth saving. It will be a fun project nonetheless.
Not sure I want to put money into the '69 motor since it's kind of an oddball being shorter than the later blocks, though that may work in my favor with hood clearance... Good tech question there, putting a stroker together with the '69 block. I know the '75 motor will need to be gutted and rebuilt, so the cost difference between a new factory spec vs stroker rotating assembly is virtually nothing, making the idea of a stroker motor a no brainer. Even if I don't intend to rev the motor beyond 6k RPM, the additional cubes will just help give this motor diesel-like torque.
So yeah, haven't decided yet, still waiting to see what my budget will be like when I get to the car. If somehow I come up with an extra couple grand, then I'll probably splurge on aluminum heads and make the motor a little more rev-happy, and if I'm broke then it'll be a torquey cruiser, either way I'll be happy and it'll be a cool car... As cool as a '75 T-Bird can be, anyway.
