Eagle Small Block Mopar Stroker Kits 340 360 408 410 5.9 Magnum Stroker
Kits & Rotating Assemblies

Mopar 340, 360 and 5.9L magnum engines make good torque and horsepower,
even with a stock stroke crankshaft (the 340 is a little weak at low rpm due to the short
stroke), but an Eagle small block Mopar rotating assembly or stroker kit will improve the
performance and durability of these engines considerably. If you are rebuilding a 340
Mopar and want a stronger rotating assembly, but do not want to go to a stroker crank, we
have a stock stroke 340 competition kit for you in addition to the 360 stroker kits. We
offer stock stroke 360 rotating assemblies, Dodge, Plymouth, Mopar 360 stroker kits,
and Dodge 5.9L Magnum stroker kits. We also offer custom piston options on these
basic stroker kits, so if you want something like a different compression ratio piston, or
different bore size piston, or both with your kit, we will be happy to take care of that
for you. If you want a piston set with different specifications in your stroker engine kit
please and let us know what you are looking for
and we will be happy to get a quote back to you, for your exact application.
We offer the Eagle 340 stock stroke rotating assembly, but at this time
there is not an Eagle 340 stroker kit available. We do have 340 stroker kits
available with other manufacturers parts though. You can find the 340 stroker kits listed
elsewhere on our site or please feel free to contact us for help with those. We have the
360 Mopar based engines covered with Eagle stock stroke rotating assemblies and Eagle 360
stroker kits and 5.9L Magnum stroker kits in both the basic street strip type and the full
competition kits. These kits are available balanced or un-balanced if you prefer to have
your local machine shop do the balance work for you.

Engine Kit Contents Description
Our Eagle small block Mopar stroker engine kits offer a great balance of strength,
performance, dependability and affordability. Each of these kits includes either a Eagle
cast steel crankshaft (street strip kits) or a 4340 forged steel crankshaft (competition
kits), I beam or ESP 4340 H beam connecting rods, forged pistons with valve reliefs, moly
file fit piston rings, main and rod bearings. The 340 360 and 5.9 Magnum stroker
kit comes with a crankshaft that is designed to be used as either internal or
external balance, depending on the type of crank included with each particular kit. The
cast crankshaft kits are designed to be used as external balance, while the kits including
a forged crank are intended to be used as an internal balance assembly.
Click on the part number in the small
block Mopar rotating assembly and stroker kit tables below for the kit you are
interested in for pricing, or to order. Part numbers listed with a "B" included
in the part number indicate that the price for that kit includes balancing before
shipping to you. Part numbers without the B in the part number must be balanced before
installation into your engine.
