The Tremec has the same bolt pattern as the toploader, and the input shaft of the standad Tremec uses the small toploader (1-1/16" 10 spline) design, but the shaft is a little longer. To use a Tremec behind a toploader bellhousing, a spacer plate must be used.

McLeod sells these. It's on page 4 of their online catalog.

http://www.mcleodind.com/catalog.PDF

Part #8624 is their standard small block toploader bellhousing. Part #8625 is the same unit, but comes with a spacer plate for use with a Tremec. The part number of the spacer all by itself is #8607. I would say the spacer could be used with an FE (or other) toploader bellhousing as well. I'd call McLeod to get the details.

If you want to step up to the strongest version of the Tremec, the TKO, or even the TKO II, you get a large input shaft and big 31 spline output. These later Tremecs are STRONG, and will hold up to some serious torque. (the standard Tremec should be fine for anything without slicks, and most cars with them) I belive these TKO trannys even come with the larger slipyoke included.

There are several knowledgable places to purchase these transmissions. One is D&D, another is Hanlon Motorsports. http://www.hanlonmotorsports.com/

Hanlon offers a cable clutch conversion for early Ford mechanical applications. Mustang Steve offers a conversion at a good price. Here is a write-up with pictures of his product.

I wasn't aware of that trans' girth... bummer

First gear is real low anyway, isn't it? Like 3.xx~ something?

If you don't want the spacer, the input shaft can be shortened by a competent machine shop. Just my $.02 worth.

My T-5 has held up so far behind the 347 but will be soon be replaced by a T-5-Z with the 2.95 first gear. The current 3.35 is too much.

The Tremec's input shaft is 7.2" long from the front of the trans case, the small block (long pilot shaft) toploader is around 6.5". Big block (short pilot shaft) toploaders are 3/8" shorter @ around 6.125"

Dan Williams Toploaders says you can use a small block (long pilot shaft) toploader behind a big block, but I've heard of people bottoming the input shaft into the crank doing this with some combos as well. The McLeod spacer should be plenty for big block cars, but I'd trial fit the tranny with some clay on the front of the input to double check clearance to be sure. If it's too tight, all you have to do is shave a little off the front of the shaft with a grinder.

I'm using the stock Z-bar, which I prefer, you will get arguments on all clutch mechanics, which is better?. I just like the old style. I also used the 5/8 spacer plate with a stock old vintage bellhousing on both my 65 and 66.

Yes, the TKO's have a 1 1/8" diameter, 26 spline big block Chevy style input
shaft (requires a Chevy clutch disc) and a C6 style 31 spline output shaft.
Note that you still use a small block Ford pilot bushing.

Yes, my TKO came with a C6 yoke.

My '66 didn't require anything of the sort. The Tremec TKO cleared the
transmission tunnel without any problems. Thanks to the internal rail
shifter, there are no shift rods on the side so width is not an issue.
Things are tightest on top, but I used a JBA crossmember (tubular with
parking brake) that cants the tail end of the transmission down to provide
the required vertical clearance. To install the transmission, the shifter
must be removed (use a piece of duct tape to cover hole from tunnel crud)
which requires the lateral shifter pivots be tightened after the transmission
is installed. The front pivot bolt requires an obstruction box wrench to
reach, otherwise everything is easy to get to. I don't know if JBA is still
selling the mounts but I believe others (like Darkhorse) are.

With my combination of engine, transmission, and rear end, I had to use
wedge shims on the leaf spring mounts to get proper driveline phasing.
Another guy I know had a TKO installed in his '69 behind a 428CJ. His
installer opted to shim the trans mount to level the engine so the shaker
hood scoop was at the proper angle. A little tunnel work was required in
that case.

> Are the tunnel mods only required for some 65/66 stangs?
> On my '69 I seem to have plenty of room above the toploader.....

No modifications necessary on my '66 fastback with Tremec TKO and
scattershield.

Well the T-10 in the car i will keep just in case this does not work. I have another one that has a damaged 3rd gear and a loud reverse. i all ready have the rebuild kit with a new counter shaft and all new forks and sync's for it and now have no use for it.
