I have a 354 hemi from 1956. You manufactured an transmission adapter number 4020 for the 392 hemi that mates a Ford standard transmission to the motor. I want to use one on my 354 block. Will this work? What Ford transmission will this work with> Would this work with a Tremec 5 speed ?
Thank you,
Craig
The Offenhauser part number you are inquiring about is part number 0402. The adapter is design to use the 4 bolt 49-64 Ford manual transmission and will work on your 354 engine. In 1964 Ford introduced the “Toploader” transmission, which retained the early 4 bolt pattern. The 1964 Toploader used a small 4 hole main case with the small O.D. bearing retainer. All 1965-73 cases were wide 8 hole cases with the large O.D. bearing retainer.
The Tremec 5 speed was used by AMC, Ford, GM, and Chrysler (to name a few). Because of this, you will need to contact a T-5 specialist in order to determine which T-5 will mount and can be used with the 0402 adapter.
