Okay here's the deal, I'm planning on dropping a 393 in my 88 T-Bird. I have an Eagle rotating assembly, Cast crank, I-beam rods, and 273CP Speed Pro pistons (10.8:1). They're going in a 72 block, .060 so i believe that makes 399, using a custom grind 300 duration flat tappet cam with .540 lift, and a set of 190CC aluminum heads topped with an RPM Air Gap and a 750 Holley. I'm wondering if one of you guys could give me a general ballpark estimate on my power output. It would be greatly appreciated. Also I'm not real sure what to do with the fuel system to switch from EFI to carb, upgraded pump with a pressure regulator or what? Thanks guys! Also if anybody has a good C4 in Minnesota they're looking to get rid of, I need one..... Thanks

Hello Pierz!

Used to be from LFalls area,
spent many fun hours in the old Funhouse years back ! )

Anyway - your efi pump probly puts out about 39 psi or a tad
more, when for a carb you don't want, if I recall, over about 7 psi.

With that year of block, you should have a mechanical pump -
just disable the electric pump and run the line thru a good hi perf
mechanical pump. I think it should suck right thru the electric
pump in the tank. If not, just pull it out and devise a pickup tube
to replace it.

Pretty high comp ratio for street, even with a longer duration
cam.

For trans, are you sure you don't want to stick with an auto OD?
A good one for street is a later model 4R70W which has a little
wider gear ratio spread than an AOD, while not getting too wide,
and with very few tweaks will hold all kinds of torque and hp.
Lots of them available that bolt up to a Windsor block from
98-up V6 Mustangs. Those only have 1 less direct clutch plate
than a V8 trans, and that can be added easily.

Check out www.clickclickracing.com for some good info,
and this little write-up I did when I researched that issue.
Now I've got a built 4R waiting to go in. With that trans,
overall low gear with 3.55's is the same as an AOD with 4.10's,
but you still have much better gears for the road.

I wrote that several years ago, but most of the info is still current.

Good luck with your project!

Long term plans are also to make my 351 into a 393, either for
my LSC or my restomod 70 Mustang convert.

A good site for TBirds is www.tccoa.com BTW

Well, they have the same front end as a mustang if I'm not mistaken, they ARE a fox body..... I wouldn't think there should ba a problem as long as i use a double hump pan.
