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.

Got a response from the folks at FPA already, kudos to their customer service folks. Specs are 1 3/4" primaries with 2.5" collectors, but are guaranteed to fit with only the most minimal of clearancing required, if any. Price tag is $650 for bare steel.

This does create a bit of a dilema. The FPA headers are going to be too small to make big power with, but will be perfect for a motor making all its power by 3500RPM, lol. The smaller primaries will also help with low end torque production by keeping velocities up.

Hmmm, decisions, decisions...

That's not entirely accurate. 1-3/4" primary headers might cost you 25hp at the peak on a 650hp engine vs. 2-1/8. There will be no losses below ~4500rpm, and possibly some gains.

Questions you should need to answer are: How do you plan to use the car? How often will you be spinning the engine above 5000rpm? Will you be running mufflers all the time?

Yes, lol. I washed and waxed it and put it back under a brand new car cover. It's funny someone offered me $1k for it the other day, and while contemplating it I blew the dust off and sat in the driver's seat and made vroom vroom noises, and decided it's time to get this yacht back on the road one way or another before it hits a million degrees in a few weeks and I lose my motivation to wrench until October when it dips below 100 degrees again.

So right now I'm looking for a decent short block, don't care what vintage, that I'm going to put a mild cam in with some ported C9 heads I have in my shop collecting dust, install an electric fuel pump and new braided lines, a Performer intake or equivalent, 750-800cfm carb and dual exhaust and call it good.

It won't be a monster, but it'll get me to and from the Saturday night car shows just fine.

Unless I stumble on some extra coin in the not so distant future and run the heads up to the local machine shop for some bigger valves...

How are they 'shorter'?

I've never heard of any variation in block hight.

I've found it on a number of websites including the reincarnation-automotive site, the '72+ blocks have a little bit taller deck height than the '71-prior blocks.

Cool

I am looking at a local 1972 bird that is the same color dayglo copper with just 89,000 miles on it. One owner. Son got when dad passed away but it has sat outside for 3 years.

Excellent shape inside with great chrome and faded paint. Needs a battery and radiator.

The price is right and I have everything i need to put together a 557 sitting in the shop... Hmm.

I have helped two clients with their T bird combos. Dan E is one and knows his stuff when it comes to many areas.

Just shipped the 425 hp 515 tq 460 engine to a client in texas for his 1973 bird. The key is a high torque combo with a broad power-band. Don't get hung up on peak numbers. Average power is key.


Check out our FB page for pics of the cars and engine specs etc... The link is in my signature line.

I love making mongo big cars go very fast.
