The cylinder head bolts need to be tightened to 140 foot-pounds and the intake manifold bolts get tightened to 30 foot-pounds. The following year, Ford introduced fuel injection to its big block, which then had a 225-horsepower rating. The engine was the premier big block engine for Ford trucks. The 429-cubic-inch V8 and an enlarged version displacing 460 cubic inches were first used in 1968 Thunderbirds and Lincolns. I didn't notice any huge change, but that's because my timing was already set around 11° when I got the truck from my dad and I only advanced it by 1°. In its final years with Ford from 1994 to 1997, the big block achieved a horsepower rating of 245. Ford's 460-cubic-inch engine ran mainly in pickup trucks.
The Ford 460-cubic-inch, 245-horsepower engine was used in many applications, from midsized cars to large luxury cars and Ford's line of trucks. Basically, it refers to engines bigger than 332 cubic inches. Considering you can sometimes push it to 14° or more, those people see a huge gain in power relatively speaking. When talking Ford engines, big block means the 460-cubic-inch engine, which was born during the muscle car era and was the last big block engine used by Ford. In 1983, Ford decided to retain the engine for its towing power. The output for 460 engines built before 1972 is 365 horsepower at 4,600 rpm and 485 pound-feet of torque at 2,800 rpm. Depending on where your timing is set right now, it may just be a little more power, or a substantial amount.
During the oil crisis of 1972, the 460 was changed to get better gas mileage. Horsepower dove from 365 down to 245, and then to as low as 208 horsepower. To differentiate a 429 from a 460, check the orientation of the thermostat housing on the front of the engine block. The 385 engine family can be identified by counting the number of bolts that hold down each valve cover. I don't know why it happens, but I seem to read a lot of posts where people say that they checked their timing and it was only 6-8° of advance timing when stock is 10°. Engineers dropped the 385 family for better fuel economy, according to John Hix, a Ford mechanic and classic car owner.
A typical 460-cubic-inch engine in 1968, with a bore of 4. The engine was the last of the Ford big block engines. After the mid-1980s, carburetors were replaced with electronic fuel injection with an output of 245 horsepower and 400 pound-feet of torque. All other Ford V8 engines have a different valve-cover bolt count. This weekend I'm looking to try pushing the timing a bit further again. The intake valve had a 2. The 385 family had overhead valves with two valves per cylinder.
Also, as timing is increased, it will help improve the efficiency of the motor slightly, so you may see a slight increase in fuel economy but don't bet on it with the 460. If you stay with 87 or 89 octane fuels, you won't be able to advance the timing far enough to really feel any difference in where the power band is situated, but you should notice a bit more power overall. If it is pointing upward, it is a 460. In 1968, the 460-cubic-inch engine could obtain high torque and horsepower ratings due to lax emission standards. The same can be said for that throttle body spacer.
When Ford's full-sized cars were downsized in 1979, there was no longer a need for the 460 V8, but it continued as an option in the F-Series trucks and E-Series vans into the 1990s. The 385 came in three engine sizes: the 370-cubic-inch, 6. At first, the 460 was exclusively a Lincoln engine, but when the 429 was discontinued in the early 1970s, the 460 took its place in Thunderbirds, Ford and Mercury cars, and F-Series pickup trucks. The Ford 460-cubic-inch, V8 engine has a cylinder bore of 4. The output for the 460 starting in 1972 is 212 horsepower at 4,400 rpm and 342 pound-feet of torque at 2,600 rpm.
Rocker arms are tightened to 20 foot-pounds, while the oil pump retaining bolt gets torqued to 25 foot-pounds. The compression ratio was lowered to 8. That is all those chips do, you can do it yourself and save the money for something else. It won't be a huge change, but every bit helps. And in the future he was gonna get this hypertech chip click link below , what do you think it will add in power?.
. If you've made modifications to the engine, intake, or exhaust or run higher octane fuel you might be able to get away with even more advance. Ford 460 main bearing caps need to be tightened to 105 foot-pounds, while connecting rod bolts are tightened to 45 foot-pounds. As emissions restrictions mounted, a notable decline in performance was noted, which eventually led to the demise of this engine. If you count seven bolts, then you have a 429 or 460 V8. The compression ratio is 10.
The name comes from its 3. The 460-cubic-inch engine had a marine application and was also used in Ford's big luxury cars. You already have headers, bump the timing a few degrees. . . .
