And if so, which should I use now? The compression ratio was lowered to 8. For the most part, the max horsepower stayed between 205 and 275 hp for any factory built motor with max torque ratings between usually being between 345 and 375 lbs. The 385 engine family can be identified by counting the number of bolts that hold down each valve cover. Just a plain ol valve, stainless, Inconal, Stellite or sodium filled. Thanks, Neil I recently had my motocraft 4bbl rebuilt after my engine performance went real weak on my 75 supercab, 460. However the 4180 was made into an emissions carb and hurts performance and fuel economy.
It was used on several engines at one time or another. I replaced mine on my 1984 F250 Super-cab, Super-duty, 460 with C6 and 4. Has anyone heard of this before or tried it? Thanks, NeilDon't need the info. I would like to thank both of you, for your help you have given me while I was dealing with the 460. I replaced mine on my 1984 F250 Super-cab, Super-duty, 460 with C6 and 4. There were 2 barrel 429s, but no 460 ever came with one. The 460, although discontinued in the late 1990s, remains a popular big block engine that is widely used in motor homes, boats, and industrial vehicles.
Rocker arms are tightened to 20 foot-pounds, while the oil pump retaining bolt gets torqued to 25 foot-pounds. Catalog numbers are different, of course, but is there any drawbacks to this or is the timing the same or close enough, between a '69 specifically 429 C J and a '75 460? The worst year for the factory heads of the 460 was 1972 due to a poor design of the quench area which is the area distance between the piston at top dead center and the flat surface of the cylinder head. Essentially the 1972 model heads had little to no quench area and were known to explode on the inside. To differentiate a 429 from a 460, check the orientation of the thermostat housing on the front of the engine block. After the mid-1980s, carburetors were replaced with electronic fuel injection with an output of 245 horsepower and 400 pound-feet of torque. Same thing as a stretched timing chain when the extra free-play is in the chain then. If it is pointing upward, it is a 460.
Best way of confirming this is to find the plastic pieces floating around in the oil pan. Ford redesigned the heads for 1973 and after but still suffered from the poor exhaust port issue. All other Ford V8 engines have a different valve-cover bolt count. 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. . Thanks in advance, Neil Ok, since we dont have edit I cant add to the first post so I got another question. We now have a newer motorhome, 99 model with the 275 hp V10, 4L100 trans on a Ford F-53 Chassis.
Yet my brother says it sounds like a timing chain needs replacing since the 70's Fords came with the plastic-coated timing gear in them while aftermarket ones are full metal. 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. The compression ratio is 10. No change in the weak performance. The cylinder head bolts need to be tightened to 140 foot-pounds and the intake manifold bolts get tightened to 30 foot-pounds. Thanks again, Neil Don't need the info. I at first presumed the heads were bad.
This design, combined with a valve sizing of 2. Throttle response was greatly improved and mpg was up 2 mpg and when you were getting 6. A stock 460 cylinder bore was measured at 4. No problems with the engine or trans so far, but if there is, I know where to come for help. I have considered it but thought i would post first on this forum of seasoned professionals for feedback. After 73 ford retarded the cam timing for emissions purposes.
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. The 429-cubic-inch V8 and an enlarged version displacing 460 cubic inches were first used in 1968 Thunderbirds and Lincolns. The engine was featured in the Ford Torino, Thunderbirds, and Econoline models among many others. 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. I would think that I stick to 460 timing and gap numbers if I tried it.
If you are looking to over-bore a 460 then it can easily handle a 0. The Holley carb I used is an old Holley List 1850 from back in the 1970's I have had in one of my goodie boxes for years. The Ford 460-cubic-inch, V8 engine has a cylinder bore of 4. Ford 460 main bearing caps need to be tightened to 105 foot-pounds, while connecting rod bolts are tightened to 45 foot-pounds. You can just order an aftermarket roller timing set adn use the zero degree setting and do the same thing usually cheaper then looking for factory replacement sets. Last long trip we made, west, out on I-40 she was running about half throttle pulling 24,000 lbs down the road, so I was well pleased.
However the 4180 was made into an emissions carb and hurts performance and fuel economy. If you count seven bolts, then you have a 429 or 460 V8. The intake side of the head provides a cross-sectional oval port which helped give the engine the high torque ratings that it was known for. Throttle response was greatly improved and mpg was up 2 mpg and when you were getting 6. . .
