Which is the best head for a 318 engine?

The small chamber of these heads give your 318 a higher compression ratio, which is good for both power and fuel economy. If you need to build a low compression engine, these are still the best heads to use, but run them with dished pistons. Some builders report that for two otherwise identical engines (including compression ratio)]

How much horsepower does a Mopar 318 have?

A street-worthy 318 can easily make 400 horsepower, about what a lot of street 360s put out. When the engine in my 66 Barracuda needed to be rebuilt, I decided to replace the stock 273 with a modified 318. Forty five extra cubic inches equals lots more torque and horsepower, and the 318 is a bolt-in replacement for the 273.

The 318 A, LA and 5.2 L Magnum series engines all use the same stroker kits since the bottom end rotating assembly of these engines are all the same. The pistons vary as needed to provide the desired compression ratio with the cylinder heads you will be using. We have a wide range of 318 stroker applications covered with our kits.

Which is the best intake manifold for a Mopar 318?

The best intake by far for a 318 running “high swirl” cylinder heads is the Weiand 8007 Action Plus Intake Manifold. Running a large port intake with 318-style ports causes a “damn” in the intake path where the intake mates to the head because of the port mismatch.

What kind of pistons do you need for a 318 Mopar?

Purchase a set of cast or — preferably — silicon-alloy hypereutectic pistons designed to deliver a 9.5-to-1 compression ratio with a 72 cc combustion chamber. Instruct the machine shop to balance your rotating assembly (crankshaft, rods and new pistons).

If you like it (or not), leave a blurb in my guest book. The small chamber of these heads give your 318 a higher compression ratio, which is good for both power and fuel economy. If you need to build a low compression engine, these are still the best heads to use, but run them with dished pistons.

Done this a couple of times; no bore nothing required, but IMO a waste of time. The 318 is compression challenged to say the least, and big port heads just make it sluggish out of the gate. And the 340 cam just makes it more sluggish.
