I got to take a look at the '81 Capri 200/4spd:
Unique car for sure, I couldn't tell engine numbers but it had a high-mount 2 bolt starter and 3+1 OD 4 spd behind recent engine replacement. . Original paint had RS 3.3 on fender behind front wheelwell . Feedback carb tubing/wiring everywhere and big cat-cvtr exh. manifold. Needed over 50% resto with rotted frame rails and inner fenders. I told owner: 'hopefully someone that can handle full project will pay asking price'. I also explained the important SIX drivetrain would live-on if he accepted my salvage price offer.
have fun
The 1980 to 1983 3.3's had on occasion, an adjustable idle kicker for the A/C unit if so equiped, and an idel stock soleniod and choke pull off, and for 1981 to 1983, a bowl vent soleniod, but even with all that, there wasn't even a computer. They were much like th 5.0 M code 4-bbls, a totally non feedback carb car, but it looked scary enough to be one. It
lookes like a Feedback F150 carb, but it isn't.
The 3.3 1981 T4 drove just like the 3.3 1980 SROD, only it
didn't even have an overdrive gear. Not sure if the gear knob did, though!
Ford gurus aren't 100% sure if the SROD in Fox 3.3 's stoped in 1980, or remained concurrent with the 1981 T4, as every magazine article has errors proven wrong by in the field observation.
From MARCH-1981-MOTOR-TREND-MAGAZINE-IMPORT-CAR-OF THE YEAR
Mercury Capri RS 3.3 4speed might have still been SROD.
Many are the 80's maliase 3.3 I6 items of weirdness, for instance, the low mount block actually was blue, not grey, for the first year it came out, in 1980. I had a guy form the US phone me and tell me not all low mount blocks are grey.
A big bell 1980 has no coded big bell C4 gearbox listed for it anywhere, as the bell housing only worked with mid 1982 on wards C5's. But there must have been a C4 Big Bell gearbox made for it.
Ford quoted the 1980 3.3 Fox Mustang and Capris with SROD as having a 2.49:1 final drive ratio in top, even though SROD's came with a 3.08 diff standard. There was no "2.49" diff ever made, so that makes the top gear an 0.81 overdrive with the 6.75, or 7.5" 3.08 non limited slip or 7.5" limited slip
For manual 1980 US Fox 3.3's there were only 3.08's and 2.73, and for 1981 manual Foxes, 2.47's. The new Limited slips were only 2.73's or 3.08's for 1981.
Some 3.08's and all 2.47 were 7.5" diff ratios. Others were 6.75" diffs in 3.08 or 2.73.
The 1981 4th gear behaved like an SROD one, but the details were interesting...

The work GM and Ford and Jeep did to get the T5 together was pioneered by the 1976 T50 and 1974 SR4 gearboxes, and the 1352 3.3 T4 gearbox case was the birth of the Ford T5 gearbox. Same case, just different extension housing.
