The Y-block was the same displacement as the old Ford Flathead V8 that it replaced but with a bigger bore and a shorter stroke (3.5 x 3.1 in). It produced 130 bhp (97 kW) at 4,200 rpm [ 5 ] as opposed to the flathead's final 110 bhp (82 kW) at 3,800 rpm, [ 6 ] an increase of 18%. [ 1 ]
Note: this is commonly called the Ford Small-block V8 pattern, though it is used in some "big block"-sized V8's as well as some V6's and I6's. 200 I6 1978-1983 only, partial (4 of 6 bolts) pattern. 250 I6 (except Australian 250/4.1) 255 V8; 289 V8 - (made after August 3, 1964) - had 6 bolts holding bellhousing to block; 302 Cleveland (Australia)
The early Super Duty has a unique intake system where the intake plenum is connected directly to the cylinder head; all four cylinders pull the air/fuel mixture from a single "log" type port in the head. The engines could "spit" when cold and blow the choke plate out into the air cleaner because of the large port configuration. In later engines ...
In 1958 they replaced the Lincoln Y-Block with the much larger MEL (4.9") and the Ford FE-series (4.63") was also introduced. Ford would continue to offer three basic block sizes through 1976 with the Ford 335-series taking the place of the Y-Block after a three year overlap (1962-64) and with the MEL replaced by the 385-series (4.9") in 1968.
The T-5 is available in "World Class" (WC) and "Standard" (STD) models; STD are sometimes known as Non-World Class (NWC). Compared to the Standard, the WC changes bearing types and blocker ring materials. [3]
Y bodies built for 1976-1980 used a GM-standard 13 character Vehicle Identification Number, or VIN, with the second character denoting the series, followed by the body type, engine code, model year and assembly plant. [1] Y bodies built for 1981-1984 can be identified by the inclusion of the Y as the fifth character in the 17 character VIN.
T5 retrofit conversion can maintain existing lighting levels with the higher efficiency of the T5 lamp. However, with kits that operates the lamp on the existing magnetic ballast, the efficiency drops and the lamp life is considerably shortened, as T5 lamps aren't designed to be operated on mains frequency but only on high frequency.
