Installing an 200-4R automatic overdrive to a 352, 360, 390 and 428 Ford FE engine is a good option

Overdrive transmission solutions for 352, 360, 390 and 428 FE engines
I remember back in the early ’90s I went to great lengths swapping the Saginaw three-speed in my ’54 Chevy Bel Air for a Muncie four-speed and a Powerglide ring-and-pinion. When all was said and done, yes, I had a much beefier transmission in which to bang gears and the freeway speeds were a bit easier on the rpm, however, for the time and money spent I can’t say that I was all that impressed.
A few years later I acquired a ’55 Chevy Stepside which, lo and behold, had that same three-speed gearbox—this time, however, behind a small-block 350. When the opportunity arose to swap out that manual trans, let’s just say the word Muncie was not on the tip of my tongue. While I did opt for a four-speed, in this case I went the automatic overdrive route and the outcome was anything but mediocre. From that point on, any transmission upgrade I’ve done has been so with the intent to add that crucial overdrive element—whether it was the TREMEC TKO behind the 235 in my ’53 3100 (as well as my Flathead-equipped ’33 Ford) or the 200-4R in my ’53 Bel Air.
Speaking of 200-4R overdrives, it was that above-mentioned swap that sold me on the beefed-up, compact four-speed auto as a perfect option for smaller-spaced applications (in lieu of a 700-R4 or 4L series) without sacrificing performance and durability. While the cores are not as common as the bigger 700s due to lower manufacturing numbers, they are still available (remanned, and new from Hughes Performance; Phoenix Transmission offers full levels of 700s as well as TH350/400 and an array of 4L series applications; and Bowler offers 700-R4 packages). The important factor when choosing any overdrive is whether you want to go electronic or manual control—if the latter, you’re limited to the 200/700 series. When the opportunity arose to swap out the three-speed manual in the ’67 F-100 in our shop, well, let’s just say none of the Ford ODs were the first options to come to mind … at least in my mind, that is.
A GM transmission behind a Ford engine, you ask/scoff? And if so, how so, you ask? Yes, and, for starters, it’s as easy as picking up the phone and ordering a transmission adapter kit from a name many a hot rodder ought to be very familiar with: Wilcap Co . in Pismo Beach has been producing machined ways in which to mate engines and transmissions, among other things, that were never originally intended to be mates, so to speak. And since 2002, Patrick McGuire has been keeping that tradition alive—offering a wide array of adapter kits … including the 390-350 kit that allows users to bolt a GM TH350-400/700-R4/200-4R behind the ’58-76 Ford FE series V-8 (332-428 ci) that we acquired for said swap.
Wilcap’s 390-350 engine-to-transmission adapter kit includes the following: their in-house machined and Blanchard-ground aluminum adapter plate, steel flexpate with brand-new ring gear, billet crank spacer, alignment dowels, and all necessary Grade 8 hardware. Additionally, we acquired the Mopar mini starter specifically modified for use with this application.
To manually control the shifting of our 200-4R, we chose to use Lokar’s TV/kick-down cable system (KD-2200RHT) and carburetor bracket (SRK-4000). Since the F-100’s radiator was ill-equipped for automatic transmission cooling capabilities, we obtained a Derale Series 10000 stacked-plate remote fluid cooler to mount below the radiator itself. And other than supplying our own urethane tailshaft mount, the only other thing we had to provide was the time in which to perform the swap. (Of course, the aid of Harbor Freight’s tranny jack and support stands greatly helped, too!)
For all you non-purists who have stuck around—follow along as we modernize this beautiful old Bumpside’s highway driveability. Next month, in lieu of modifying the three-on-the-tree, we’ll wrap things up with a new steering column install to accommodate the actual shifting requirements. a GM TH350/400 or 200-4R/700-R4 behind a ’58-76 Ford FE (532-428ci) is the above-pictured adapter package from Wilcap Co. Their 390-350 kit includes everything shown, minus the actual transmission and torque converter, of course, to perform the swap from the OE Ford trans to a three- or four-speed automatic. The modified high-torque Mopar starter is available from Wilcap as well.With the 700/200 overdrives, unless it’s a later production transmission (to the best of my knowledge), you need to “efficiently” control the shifting via cable. But unlike a traditional kickdown, such as the TH350/400 used, the overdrive’s TV cable is crucial to the transmission’s performance and longevity, and thus the use of a proper connection to the carburetor/throttle body is important. For those reasons, we chose to go with Lokar’s 200-4R cable and bracket/spring kits.
