As you requested 55blacktie.

I love this setup, its snappy off the line, 0-80 in short order, 20 in vacuum, idles very smooth at 800 rpm and sounds great.
Air Cleaner: X-Stream Airflow, capable of supplying 680 cfm: 327 ci, 6000 rpm, no boost = max draw – 568 cfm (cut down the base to fit under the hood.)
Brawler Street Series, 600 cfm, Mechanical Secondary, Electric Choke (Ted has proven that a vacuum secondary can be a better choice.)
Blue Thunder intake, plenum dimpled
Carter Street Super Mechanical Fuel Pump (FE pumps fit.) RobbMc offers high performance options.
FBO distributor, 4secondsflat is awesome.
Wagner PCV valve (a noticeable improvement off the line.)
Valve cover breathers
FPA headers 2 ½”
Porter mufflers 2 ½” in and out
14° initial timing at idle with no vacuum
Full (not timed) manifold vacuum adds 16° at 16” = 30° at idle
at 3400 rpm 22° = 36° all in
Approximate weight of vehicle        2900 lbs
Compression ratio if over 9:1          N/A
Trans Type                                           Auto w/ 2000 rpm stall
Rear End gear                                      3.31:1
Cam duration at 50 if over 208        218
Aluminum or iron heads                   113s mild porting






.150 Stroked Y-Block:327.25 ci @ >1hp per ci
 

Thanks, again, Brent. I sent a PM to you, fearing that it might bore other forum members if I posted it.

Don't let that worry you. I too would like details of the build also.

If it bores others, they can click out. 

1) Mechanical fuel pump or electric

2) TRANS type

Carter M6905 mechanical pump made in USA. More than likely will also have an electric pump (Carter P4070) for starting. C5 transmission/w C4 2000 stall converter, C4 valve body, H servo, Green Stripe vacuum modulator, Dynamic Racing Transmission wide-ratio gear set (2.90; 1.60; 1:1), and modified governor secondary valve that will allow 5600 rpm upshifts in Drive; downshifts not affected.

Brent, although I sent PM last night, there is no record of it in my Sent Items.

THANX! for the build info ...

I would like to retain the original 55 Tbird shifter, but there seems to be no way to use it with the C4/C5 and be able to manually shift into and out of Low. Someone suggested using a Mustang C4 shifter, but I don't like the T-handle. I'll probably use a Lokar shifter, but it involves modifying/fabricating a shifter plate for the transmission tunnel for a floor-mount shifter. Also, Lokar says that the C4 combination neutral-backup switch can't be used with the Lokar shifter. The Lokar comes with a neutral switch but no backup-light switch. Although my 55 doesn't have backup lights, the wiring is there; I might want to add them in the future. Parking lots scare me. 

55blacktie, this may be irrelevant to why you may not be able to use your original 55 shifter but if it's because you need 6 positions/detents when there are only 5, maybe this will work for you. -  Many years ago when installing a Cruise-O-Matic in my '57 Ford I drilled an extra 3 holes is the shift lever on the transmission and used one of those drilled holes to gain more throw for the "green dot." In this case, it worked very good in that neutral, reverse and park were where they shouold be on the shifter.  Thanks for the above information....

I've seen numerous C4/AOD conversions, even with the other guy's engine & transmission, and they retained the 55-57 Tbird shifter, but I have found nothing about being able to manually shift in and out of Low with any conversion. Most have no problem with that because the transmissions will automatically shift through all the gears, including Low, unlike the Fordomatic, but I want the C4 to fully work in both modes.

Thanks for your reply. 

Most of the C4 conversions, mine included, have not been able to use  manual low although second is manually available.  I had a friend that was able to do so by fine tuning the shifter, but he had problems with it staying in park.  I believe he reset it so park was ok, but lost manual low. Since I don't go racing, it is not a problem and I still can downshift into second for the long downhills to help braking.. I haven't had any experience with an AOD

I am sure it can be done, but, but I don't think it can be done with a completely stock shifter.  Some mods most likely are required.

Paul, that pretty much goes along with everything else I've read. My OEM 55 shifter is in great shape; rather than making any permanent modifications to it, I would rather use the Lokar shifter. I've seen some C4 conversions that used the Mustang shifter, but I don't like the T-handle. I will either have to modify the shifter plate that bolts to the tunnel or have one made. I won't modify it until I have another in hand.
