I want to do a standard swap in my Fairlane, and 5 speeds are more common and cheaper then a 4 speed, so Im leaning towards a 5 speed. If I use a 390 truck bellhousing with a 5 speed will that work out. I know 5 speeds have a longer input shaft then a 4 speed, and a truck bellhousing is deeper then a car bell, will this work out??? Thanx.

A Tremec can be bolted to any toploader bellhousing using a spacer made by McLeod. It's McLeod part# 8607 and comes with their standard toploader scattershield to make it usable with the Tremec transmission. It can also be purchased seperately. A picture of it can be seen on page 4 of their online catalog.

The Tremec is a bit larger than a toploader, so (especially on 65-66 mustangs) a bit of transmission tunnel clearancing may be necessary.

As for anyone looking for the strongest Tremec...

The Tremec TKO II has larger input and output shafts, as well as a MUCH stronger 3rd gear than the regular or TKO Tremec. It also uses a 0.83 geared overdrive instead of the standard 0.68. This makes 5th gear more usable in a racing situation.

I believe it has a 26 spline input, and a C6 sized output. (it comes with the proper slipyoke)

Good Luck!
