How much horsepower can a 360 make?

After-market support for the 360 is great, and with the right parts, it can easily make 450 horsepower and still have great street manners. If you need more inches, it’s easy to drop in a stroker crank and get 406 cubic inches.

What is an acceptable compression ratio?

Compression ratios usually vary between 1.05–7 per stage; however, a ratio of 3.5–4.0 per stage is considered maximum for most process operations. Quite often, the temperature rise of the gas during the compression dictates a limit for the safe or reasonable pressure rise.

What’s the compression ratio of a Dodge 360?

The 360 featured an 8.7:1 compression ration and 255 horsepower at 4,400 rpm. Its torque was 360 ft.

How do you find a good compression ratio?

The easiest way to improve compression is with a set of 64cc chamber cylinder iron Vortec heads and that 0.015 head gasket, which will push the compression up to 9.0:1. One further recommendation would be to add a set of mid-length headers to the engine. This will do more to add power than any other thing you can do.

Is the 360 a good engine?

The 360 was a very good engine, no different than the 390. A bit les horsepower, however. The biggest issue witht he 360 was that it offered roughly the same power as the 302 at the time, with much worse efficiency.

How much does it cost to rebuild a 360 engine?

Most engine rebuilds are cost-effective if done between $2,000 and $4,000, including spare parts. An engine repair like this might involve replacing bearings and seals, or even installing some engine parts again in the process.

What octane is needed for 9.5 to 1 compression?

The standard recommendation for street engines running on pump gas has always been to shoot for a 9.0:1 to perhaps 9.5:1 compression ratio. This is in order for the engine to safely work with pump gas, which for much of the country, is limited to 91-octane.

How much horsepower does a 360 5.9 have?

between 230 and 250 hp
The 360ci (5.9L) Magnum had a rated output between 230 and 250 hp.

Is a Mopar 360 a big block?

The fact is, the small block Mopar LA-engines (318, 340 and 360cid) were under-rated at the factory and were the last of the big three small blocks to be offered to the public.

Is a Ford 360 a big block?

The 360 is part of the FE series that includes the 352, 390, 427 and 428 among other motors. most people refer to them as a big block. They are heavy and have a wide intake manifold.

What is the big deal about compression ratio?

An engine’s compression ratio is a big deal. You never see a low-compression racing engine unless it is arbitrarily limited by some class restriction. Higher compression ratios yield more power in racing engines and street engines. Everyone remembers the anemic low-compression 1970s and nobody wants to repeat them.

What is a good compression ratio for a Drag Race Engine?

The Science of Compression Ratios for Performance Engines. Short tracks frequently enforce a 9:1 rule while NASCAR engines are limited to 12:1. Unlimited drag racing and Bonneville engines often exceed 14:1, while stock class drag racers are limited to the original factory compression ratio of their particular vehicle.

What is the difference between compression ratio and Cranking compression?

While compression ratio is a relationship of volumes within a cylinder, cranking compression is actually a measured cylinder pressure taken at the spark plug hole while the engine is bring cranked with the throttle plates held open. The coil wire is removed during this operation to prevent the other cylinders from firing.

What is the compression ratio of a stock Bonneville engine?

Unlimited drag racing and Bonneville engines often exceed 14:1, while stock class drag racers are limited to the original factory compression ratio of their particular vehicle.
