The "Triumph TR3B" is an unofficial name given to the final version of the TR3, which was produced in 1962. It was offered concurrent with theTR4, which started production in 1961. The "TR3B" was a special short-production run in response to dealer concerns that the buying public might not welcome the TR4.
It had the body of the later "TR3A". Two series were produced: one with a commission number preceded by TSF of which 530 were produced; one with commission numbers preceded by TCF of which 2804 were produced. Both series were partly produced in parallel. The TSF series were identical to the last run of TR3As, so with a two-litre engine but already with the TR4 all-synchromesh gear box.
This car is one of the TCF series and has the 2.138-litre TR4 engine. The engine is a straight-four, push rod, three-bearing, with wet liners. It has 9:1 compression and is very rigid. It was fitted with two H6 SU carburettors. It has 105hp (78kW) at 4,650 rpm and 172N·m (127lbf·ft) of torque at 3,350 rpm. It gets around 20 miles per US gallon (12L/100km; 24mpg-imp) to 30 miles per US gallon (7.8L/100km; 36mpg-imp). The top speed is limited to about 110mph (177km/h)
Appearance is identical to the late US-version of the "TR3A", but with different head light rims, for the rest very similar to the TR3, except for a wider grille and door handles. It weighs 2,137lb (969kg.)
This soild #2 car was restored from a very solid low mile original and has been in a private collection for the last 10 years. It runs extremely well and eveything functions as it should. With a little work, this car could easily be a #1 condition car valued at $50K.
