Mopar Engines, Parts & Components

Improved Power And Performance

Upgrading your motor with performance Mopar engine parts and components like a camshaft, cylinder heads, pistons, intake manifold, carburetor, turbo, and ignition system will noticeably improve engine horsepower and torque, resulting in quicker acceleration and improved times at the track.

A More Radically-Sounding Engine

For many, having a vehicle with an engine that turns heads by the sound it makes is very important. Upgrading your Mopar engine with a performance camshaft, headers, exhaust system, and upgraded cylinder heads and pistons will transform the attitude of your motor.

What Is A Mopar Engine?

A MOPAR (originally an abbreviation for "motor parts") engine is a nickname for any engine built by the Chrysler, Dodge, and Plymouth brands. It typically refers to V8 engines but can be applied to other performance engines from the early 1960s to the present.

How To Rebuild Small Block Mopar Engines

Depending on the engine year and size, the steps to rebuild small block Mopar engines can vary. In most cases, the first step is to dismantle the engine, carefully documenting and organizing parts. This includes the intake manifold, distributor, cylinder heads, all covers (including timing cover, valve covers, oil pan), camshaft, timing set, and rotating assembly (crankshaft, connecting rods, pistons). Next, the cylinder heads need a "tear down", removing the springs, retainers, locks, valves, and valve guides (if required). It is good practice to take the bare block and cylinder heads to a machine shop or builder to inspect them and to do any machining needed for a proper rebuild. Once the machine shop visit is complete and the parts you would like to replace or upgrade are ready (a gasket kit, rod and main bearings, as well as rings are a must-get at a minimum), the rebuilding can begin in the reverse order of tear-down. It is important to follow proper torque specifications and sequences using the correct instructions in order to have a successful rebuild and a trouble-free engine.

What Color Were Mopar Engines?

There are a variety of factory engine colors for Mopar engines:

HEMI orange: One of the most famous paint colors, HEMI orange paint was used on engines that include the 1962-1964 Max Wedge engines, 1964-1965 426 HEMI engines, as well as the 413 and 426 Cross Ram engines found in trucks.

"HEMI orange" (dark red): This dark red paint was used on 1966-1971 340 engines, as well as 383 and 440 high performance engines.

Blue: A turquoise paint used on all "B/RB" engines from 1962-1971 (except for the above high performance 383/440 engines that used dark red), and on many 340 and other LA engines late into 1969.

Black: Nearly all other Mopar engines used black paint throughout years not listed above.

What Is The Best Mopar Engine To Build For Budget?

The answer to this question is usually a matter of opinion. Whether a 318, 340, or 360 small block engine, or a 383 or 440 big block engine, as well as other sizes, all engines can be built on a budget with the correct research and planning. In general, small block Mopar engine parts are less expensive than their big block Mopar counterparts. For small blocks, the 340 and 360 are the most popular engines for budget builds.

How To Identify Mopar Engine

The best way to identify a Mopar engine is by researching the block and cylinder head casting numbers. In most cases, the serial number on small and big block engines can be found on the left/driver side of the block. the For most small and big block cylinder heads, there is a raised 7-digit number found either under the valve cover on top of the cylinder head intake runner or underneath the cylinder head intake runner.
