I often wonder if the 70mm throttle body is big eough. He did say that the air/fuel was just about perfect. Nut I still wonder if a 75 would help at all.

70mm throttle body should be ok. A 75mm might be better. I'm contemplating going from a 70mm to 75mm throttle body on my Thunderbird as well.

You're running a BBK style cold air intake correct? If so there's power to be had with a better setup. 3.5 or 4 inch tubing between the MAF and throttle body will make more power. Also a 9 inch long conical filter clamped to the end of the MAF will make more power than the cold air intake you have. Basically just copy the setup I'm running ;). I know you're running a Cobra computer and MAF but a larger than 70mm MAF will help a bit too.

All the above changes could get you ~ 10hp or so. Maybe a bit more.

If there is no vacuum being created at WOT, at larger throttle body is totally unnecessary...

Vinnie is the hole in the intake bigger than 70? I see you had TMoss work it, not sure what the result is with a GT40 intake. I think the 65 fits my TMoss-ported H.O. intake perfectly.

Vacuum is a measurement of restriction. Without vacuum there is no restriction.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

The upper was untouched as the tubes don't allow for porting (tubular GT-40), and I'll check the opening. If it's not 75mm, I can make it 75mm easily.

True. However every time I've upped the size of some induction piece on my Thunderbird (MAF, throttle body, air filter, intake tubing) the car has gone faster in the 1/4 mile. It may not be necessary but for some reason it works.

Air is a compressible fluid. Pretty much all if it stays where the crazy white haired Asian guy on discovery channel goes. You can call it out everytime. As soon as it stops making sense, he pops up. Same with the guy on ancient aliens, not that there is ever much fact sharing there.

It's all theoretical physics. Part of the reason mustang guys can't figure out where the boost dropped on a s/c setup when they get better cylinder heads. The math says they had plenty before.

Then you had some restriction... No doubt sometimes it's so small that it's difficult to measure on a std vacuum gage... I never had more than a 65 on my 5.0, was happy with how it ran so never messed with it...  I have a 70mm for the 331...

No doubt. With the 65mm throttle body on the car a vacuum gauge would show 0 inches at WOT. I switched to a 70mm throttle body and it still showed 0 inches at WOT. However the car went 1 mph faster with the 70mm than the 65mm throttle body. Go figure. If I can find a cheap enough, quality (Accufab or Edelbrock) 75mm throttle body I may try it to see if it helps.

I think up sizing components (to a point) helps the engine accelerate and reach peak power faster, thereby improving 1/4 mile times. Sometimes changes won't show much power on a dyno or other measurement tool but help none the less.

My 70 is fine, but I'd like to try a 75mm throttle boy. I have no funds for that for some time, but one day. My friend has a 75 on his 351W F-150. I'll borrow his and see if there's a difference.

Thanks, the car does just fine. I rarely even hot rod the old Bird. Most of my driving is 2 miles to work, two miles home. I'd still like to optimize what I have.
