As an example, a street vechicle only running on street tires. The interior is in immaculate condition as well. The compression ratio was lowered to 8. The following table lists crankshaft main bearings by engine application as identified by the bearing manufacturer. They're everywhere, making them a simple score for an easy 500 hp from the Ford 460.
The engine was also installed in the Lincoln Continental for a time as a consumer car option. On the other hand, an M-block engine in factory trim has vast, untapped power potential. This one is lots of fun. The 429-cubic-inch V8 and an enlarged version displacing 460 cubic inches were first used in 1968 Thunderbirds and Lincolns. Exhaust port flow is so poor that using a big cam will only kill power across the board. The company offers both track and street versions that are also worth investigating and are priced competitively with the Edelbrock castings. After the mid-1980s, carburetors were replaced with electronic fuel injection with an output of 245 horsepower and 400 pound-feet of torque.
To create a solid foundation, we decided on also investing in a good short-block with a set of Federal-Mogul forged Speed-Pro flat-top pistons in case we decided to squeeze a little nitrous in the future. Our admittedly minor upgrades improved the peak-to-peak power output of the big Ford by nearly 90 hp, with gains exceeding 110 hp at the top of the rev range. In practice, Ford did use slightly different components in the 351M and 400 for different applications and for performance reasons, such as camshafts, timing sets, and valve springs, but functionally, the engines were identical except for crankshafts and pistons. All of the carbureted 460 motors we found were equipped with 4-barrel carburetion, but 429s were also available with 2-barrel intakes. Keep redline to 7200 rpm. The higher the rpm window of operation the greater the amount of stretch. The Performer cam made some awesome torque with 523 lb-ft, but that same short cam timing only managed 406 hp.
The '77 Ford F250 offered here is powered by a healthy 460 v8 paired with a 4 speed manual transmission. 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. Plycar Fine Automobile Transportation, offers the safest, most reliable, insured, modern transport available. This assumes not changing anything else in the engine combo. Stock compression heights of the various 351C pistons range from 1. Respectively, exhaust will have to be increased also. The 385-series Fords were also offered in slightly smaller 370 truck only and 429 cubic-inch displacement, but since displacement equals power, stick with the extra inches offered by the 460s.
The motor made awesome torque and respectable horsepower with the smaller cam, but it may be a bit too short for the 9. The stock iron 460 heads are a tease. 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 compression height of the stock 400 piston is 1. Some of the most common are: 4. Rebuilding one of these Lima engines usually involves removing the block and the heads. In all the engine builds, this is factored in.
In 1971, the 400 used a flat top piston that produced a 9. Connecting Rod Bolts Engine Oil 45 ft-lbs. Verify your engine specs with a service manual for your year and model. The basic part recommendations in each horsepower level increases as rpm rises. Horsepower peak at 4,100 rpm.
To differentiate a 429 from a 460, check the orientation of the thermostat housing on the front of the engine block. Short Block: Comp Cam Custom Spec solid roller cam or equivalent Based on the High Torque. You are striving for no back pressure. After some embarrassing failures of the Tunnel Port 302 engines, Ford developed the Boss 302 and introduced it in 1969. Special Note In regards to this chart, for every listed horsepower level, there is at least 10 different combos to get that same power.
It is usually good not to advance the cam as much as usual. 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. Would you kind enough to give me a base line for a build using the list of stuff I currently have? Bores and Strokes The 460 and its 429 cousin are big-bore, short-stroke thumpers. This minor change accomplishes two things. Two new intermediate engine options entered the mix, designed to offer a better combination of power and efficiency over the outgoing 360 and 390 cubic-inch engines. Also noted is: If differences exist between the plug specified on the emis … sions label and the owner's manual or in this chapter's specifications, assume that the vehicle emissions label is correct. Keep redline to 7200 rpm.
