Re: 401cid Ford w/tri-power
4 speed was an "over the parts counter" deal in `1961 along with the complete 3 duce setup. I believe that you could get the 390/401 from the factory but only with a 3 speed or a O/D unit. They were all column shift. The 4 speed T-10 BW trans set up was complete with shifter and boot and install instructions. All was NHRA Legal for Stock.
4 speed option from factory was only from 1962 on with Top Loader coming out in late 1963. I worked in the parts department of Hemphill-McCombs Ford taking care of warranty claims in 1964 and they were a ton of broken T10 imputs and cluster gears that were "1863'd" back to Ford. We had to keep them for Ford Rep to look at them. We had quite a collection of busted parts. Most were just thrown away after a month whether the Ford Rep looked or not.
