It may seem strange using a junkyard engine for a street machine or weekend racer, but with a little ingenuity and proper parts selection, impressive can be achieved. Mike Sealey There is some evidence that the 273 was originally meant to be an aluminum-block engine, and was to power a stillborn A-body DeSoto. This 488 cu in 8. The reason is because the valve is in that area twice—once when the valve opens and once when it closes. Nothing could be further from the truth. Modern engine management was designed to prolong engine life and reduce cold-start wear from fuel wash, not to mention counteract damaging detonation from low-octane fuel. If this modification is planned, be sure to drop the compression ratio from 9 stock to about 8.
Thanks to Bill Watson, Joshua Skinner, Dan Stern, Steven Havens, Jim Forbes, and Peter Duncan. When you remove and replace the intake manifold, you are nearly halfway to installing the camshaft. In this year, oil capacity was reduced to five quarts, including filter. The 360 was the base engine for the 1970s Chargers. In the 1966 cars, a 700 cfm carb and. A , or system, introduced oil vapor and unburnt fuel vapors from the crankcase to the intake, allowing the engine to re-use these as well. The fuel is mixed with air upon entering the nozzles.
I have worked on a couple of cars with this crate and with the big cam and big single plane they couldn't get out of their own way. During warm-up, a thermostatic spring allows the heat valve to open to the exhaust pipe so gas flow through the intake manifold crossover passage is decreased. We work with 3 of these manufacturers, so we can supply new heads for everything from a budget rebuild to a ported racing version with oversized valves. If you plan to overbore a block more than the. There are examples going both ways so check it out early. Starting with 1981, the 360 was exclusively used in Dodge trucks and. The 360 was Chrysler's highest performance V8 once the B-series engines were dropped in the late 1970s.
A four-barrel version became available in 1973. But, if it can be repaired your engine shop can help you with that analysis. Both are stainless steel valves. Accessories, Cam, And Front Cover Magnum engines featured a serpentine-belt accessory drive, a reverse-rotation water pump, and utilized a timing-case cover with no provision for a mechanical fuel pump. Suffice it to say I did not quite reach 380hp. The long runners tend to produce more low end torque than earlier models. There were many differences between the 340 and 318 apart from the bored, which made the 340 far more powerful than the everyday 318.
Since our power level will always be well below 600 hp, we decided to re-use our factory cast-iron crankshaft. The final item in our combination to be changed was the two-plane M1 intake. So, what if the head is cracked or broken and must be replaced? What you and your engine do care about is how much air the throttle body can flow. Before dropping in the crank, polish and clean all the bearing surfaces. Your engine does not care, and neither do you, what the throttle bore size is. It was still a V-shaped, 90-degree design made of cast iron.
This is actually a good thing for us, because not only did that prematurely inflate the supply of good short-blocks, it also brought good aftermarket cylinder heads into play to good effect. The displacement will determine whether a component is a torque or horsepower part. Before starting any engine project, the cylinder heads should be determined, as these fix many of the working parameters of the finished engine. The 1964-1967 273 had mechanical lifters. Of course, this part of the balance sheet may not be known until you take it apart.
I'm sorry I am a complete noob here. In 1970, Chrysler offered a special Six-Pack version of the 340 with triple 2-barrel carburetors rated at 290 hp 216 kW that was specific to and models. If the engine is already built, or the pistons are already purchased, then the solution is the Cometic extra-thick head gasket about. For the 1974 Dodge line, a new variation of the 360 was made with a four-barrel carburetor, resulting in 200 hp and 290 lb. Browse for the appropriate model, quantity, and make from all the listings to find just what you need.
The cylinder heads were another fundamental change of the Magnum engine, being designed to meet stricter requirements in both power and emissions by increasing efficiency. Thus is why you can shoot a. As with the 318, all 360s had hydraulic lifters. Now that you know all of that, we will try to suggest the best bang-for-your-buck modification in an order intended to give you the most productive improvements. It's meant to be a low end grunt manifold, and it does do that well. This handy ring compressor is used to guide the rings into the bores; a piston knocker is used to deftly urge the assembly into place.
