I have a few questions about putting a toploader behind the 429 in my '67.

The car had a C6, so I'll need a new flywheel, any idea how much that
should cost?
Can I use the clutch linkage parts from any '67-68 'stang?

Will the 429 cause any problems setting up the clutch? I've heard that
top loaders are pretty much unbrakeable, is this true?
The 429 is stock, and the 'stang will be driven on the street, maybe a few
passes down the 1/4 once in a while, will a toploader stand up to that okay?
Will the driveshaft from the C6 fit?

About how much should a toploader cost? Are 429/460 bellhousings
hard to find?

Last question, friend of mine has a F350 with a 460, 4spd with overdrive.
Are the overdrives very rare? Would there be any problem with putting a
4+ overdrive in a '67 'stang?

Thanks for your time

Since an original flywheel would be the same as a Boss 429 unit you
can figure $250-350. Try an aftermarket flywheel.

No the equilizer arm and the lower throw out arm are different.

You can break anything but they do take a fair amount of torque.

Your going to drive this thing on the street. Are you driving this car
now on the street? Must be really nose heavy. I have a 68 coupe with a
429 C6 at present. Only driven it a little (got to many other projects
to spend much time on this one). Anyone want a race car (low low $$$$)?

> Will the driveshaft from the C6 fit?

I believe they are different lenghts.

> About how much should a toploader cost?

For a big block (large input and output with short-Mustang- tailshaft)
about $600-700 of an useable one. They are commonly refered to as NASCAR
toploaders in some areas.

Like the flywheel most are the same as the Boss 429 unless you dig
around and find a truck bellhousing which may be harder to find.

No not in truck applications. There was an overdrive toploader offered
in the late 70's- early 80's. Small input and output.

Would there be any problem with putting a 4+ overdrive in a '67 'stang?

Jeff,

Now you have me confused, I thought all Mustang manual trannies had a long
tailshaft with the shifter mounted at the very back. I've had both the Top
Loader (with bellhousing) and my C4 (out of my 64 1/2) setting side by side
and they are the same length. I haven't done much with big blocks and
Mustangs, but I thought they would use the same length trans.

BTW one other redeeming quality of my Top Loader is I have the narrow bolt
pattern to the bellhousing. Makes it real fun removing the 5/8" bolts
during a clutch change!
