This engine was also supplied to International Harvester for use as an optional engine in International's trucks and from late 1973 through 1974. The 1964-1967 273 had mechanical lifters. It had a bore and stroke of 3. The cylinder head bolts should be torqued to between 100 and 110 pound-feet. It is essentially a six-cylinder version of the V8. The cylinder block remained basically the same.
This setup was utilised by Chrysler for the 1958 model year on its , Chrysler, , and carlines. The spark advance on these cars was also modified. La chrysler small block v8 engines 318 v8 engine. As such, a new engine control computer was developed for vehicles powered by Magnum engines, known as the. Hughes wrote: A couple of tips for 318s with Carter 2 bbl carbs: Mine was a 1976, and it stumbled and sagged badly from the time it was started until it was fully warmed up It did this from the time it was new. Moore, Vice President of Automotive Research and Engineering, and through his efforts the project was carried on cooperatively by our Kenosha and Detroit Engineering Departments. Pistons are elliptically turned so that the diameter of the pin boss is less than the diameter accross the thrust face.
The 1970 340-6 had the pushrod holes relocated. When the 250 was dropped in 1961, there was no V8 option for Rambler models other than the top of the line Ambassador, which was only available with the 327. It was used in and the Roadrunner and Kit Car — but was dropped in California at the end of the 1979 model year, and saw its final use in a sedan or coupe at the end of the 1980 model year. The Rebel's engine differs from the 327s installed in the 1957 Nash Ambassador and Hudson Hornet models in that it uses mechanical valve lifters and a higher compression ratio. The 360 was relatively tame through 1974, when it received some 340 performance parts and a four-barrel carb in an effort to replace the 340 as a performance engine. This 488 cu in 8. You can receive a refund by returning a suitable old core.
My 1971 Duster 340 was a bear in a straight line but try a little throttle in a turn and wheelhop off the road. In the end, it was far cheaper and faster to build than older Chrysler V8s, but no less durable — and, more efficient than the pricey polyspherical-head engines had been. From going from our polyspherical chambers to the inline valve wedge chambers we found it was a wash. This engine is designed to run on unleaded fuel with a minimum octane rating of 87. Bore center measurement was kept the same as the Gen-1 V8 at 4.
Sure enough, it had a screw to adjust the advance. Optional rear axle ratios included 2. Potter had previously worked on a V8 design for Kaiser, and they were able to get the all new V8 into production in less than 18 months. Introduced to Americans in 1964, it had a thin-wall casting and simpler wedge-heads and valves, which saved around 50 pounds over the existing A-series V8. This allows for expansion under normal operating conditions. This is a classic sign of a too lean mixture. The 273 will rev alot faster than a 318, or a 340.
The heads don't care what kind of camshaft or lifters you are using. The 273 predated hardened for unleaded fuel valve seats. In the 1966 cars, a 700 cfm carb and. Anticipating higher loads resulting from racing operation, the engineers fitted a forged steel crankshaft instead of the unit used in the 318. With anti-sway bars front and rear, the car was as light on its feet as most sports cars. These trays were also suspected to cause engine damage as they starved some critical bottom end components unless the engine was in peak mechanical shape. The package allowed for high speed with the light weight helping handling.
The 1970 340-6 had the pushrod holes relocated. The 273-318 connecting rods are similar to the 340s but a different casting with less 'beef'. No change in mileage, either. Valves are arranged in-line and and inclined 18 degrees. Another problem I had with that car was pinging at light, not heavy load.
Romney ordered his engineering department to develop an V8 as soon as possible. As with the 318, all 360s had hydraulic lifters. The Hall Effect crankshaft position sensor remained. Spark plugs were located at the peak of the combustion chambers' wedge, between the exhaust ports; press-in heat shields protected them from the heat of the exhaust manifolds. Remember, this was the time the car lines expanded to three bodies, A, B and C. The fire ring is much larger on a 340 and the gasket thickness is closely matched to a 360 spec gasket, so the compression is reduced on replacement.
