You can buy a brand new one with no core with a new DK nodular maincase from David Kee for $1,700. That's everything perfect.

Obviously, not correct for car show perfection but absolutely top knotch as far as performance.

Was in a 56 Ford PU powered by a 427 low rizer. Shifted like new and no noise. Owner is restoring with correct components. Trans came from a Mustang that was wrecked with low miles, I am told.. Will be for sale soon .

Was the seal leaking b4? if so It would be a good idea to replace the rear seal while you're there.Make sure your oil pump pick-up screen is good & clean too.
Prime the pump before you install it & reprime right b4 you fire the engine!
Good luck................

p.s. its a 3 speed stick

if it,s just the rear seals any deasent shop can fix it up no problem and not cost you a arm and leg.......

these r the test to date theres no crank walk, thers no vibe when brake torqe is appliedthis trannys been in out a total of 5 times all new motor mounts an tranny mount? please if some one could help

check with the info giacamo gave you,ask if the flywheel was replaced,i have had a cracked flywheel,vibrate and was noisy,the other rare prob was that the engine was over reveeded,and the torque converter got out of shape,i still would like to know high it was run!! if the converter was replaced,i think there ar not to be any balance weights on it,maybe giacamo,hawkrod,or mr F can lead you the right way

stay 390 the rest i feal is not worth the hassel

A 406 is a 4.13 bore and a 3.78 stroke. Your 390 block may or may not be able to handle this overbore. You can check which wall cores your block has to determine if this is even doable then sonic check. I'd just clean the bores up as needed to keep some meat for future rebuilds. You can pickup a 428 crank for a little more stroke giving you a 410 with the 390 bore. Per Dave Shoe a 17/64" drill bit shank will fit snugly between 390 wall cores and a 13/64" between the 428 wall cores. You can access the wall cores by knocking out the freeze plugs to check. G.

Didn't all the 67 S-Code engines come with the 428 crank? If this is an original engine, are you sure you dont already have that crank? I thought that was one of the things that made it a "GT" version of the engine.

you can get numbers like that with stock partsand the right cam package and headers.

I recently did my 390 motor with RPM heads, intake, demon carb, crane hyd.cam with 553/565 final lift FPA headers. THe combination produced 270 hp/320ft/lbs at the rear wheels on a mustang dyno. Just for a comparison a fellow with a 429 CJ balanced and blue printed put down 232hp and 260 ft/lbs. I am more than happy with my build up the only thing I am adding now is erson full roller rockers to free up a little more HP.

i my self was looking into the roller cam set up,but .739 lift was too steep on the crane mechanicals,meaning fly cuts,reblanacing etc;i checked the comp cams also,almost the same,i'm limited to solids,because the block was not drilled for hydraulicsbut the price difference between the flat tappet,rollers is hugh,is there realy a benifit on the rollers,i don't realy know if it's worth the price

Tim,
Yes it should be a tilt-away, check under the dash next to your steering column there should be a plunger type button there. Similar to your door light buttons. Push in on it and your wheel should tilt away.
Check with various mustang suppliers they should have some diagrams for tilt-tilt away wheels. Parts are only available used I believe.

I don't know for sure, but I would think that it could be one of many different options. There are not many cars that came with just one choice for the axle ratio (Boss 351 with 3.91's). You could order your FREE History 999 report from Ford (call 1 (800) 392-3673 and enter option 4) or the Marti report (http://www.fomoco.com/vinreports.htm) for a charge. The report from Ford takes a couple weeks, but again, it is FREE.

The standard rear gear set for the 390GT cars was typically 3.25:1. I think that factory equipped air conditioned cars got the 3.00:1, with that higher ratio set being the only option away from the standard 3.25:1. This is for 1966-68. Any other ratios, from 3.50, lower(higher numeric) had to be dealer/owner installed.

This is from memory, but I remember it well, because I thought it was ridiculous that Ford would factory install even a 3.50 set for the stick shift GT's.

3.25 is a very nice all around road driving ratio. I've found 3.50 to be very easy to live with, while with a stick, 3.89's are my preference. Any lower gearing and the engine buzz gets tough to handle along with the more frequent stops for $2.59 per gallon fuel.

Now you take a good old tough Borg Warner T-85 3 speed with Overdrive and you can easily live with 4.56's! But that's getting away from your original question.
