Is a 383 stroker internal or external balance?
This means that most standard 383 rotator packages use an externally balanced crank that requires a 400-style offset weight balancer and flywheel/flexplate. While externally balanced engines have survived for decades, heavy external weights are more likely to put a twist in the crank at higher engine speeds.
How is a motor balanced?
Dynamically balancing a motor involves adding small amounts of weight to the motor in order to counterbalance any parts that are heavier on one side than the other. That imbalance is the major source of vibration, and if you correct it, you can have a much smoother running machine.
Do all engines have a harmonic balancer?
Found at the front of the engine attached to the snout of the crankshaft, harmonic dampers are used to quell the harmonics of the crankshaft and are vital parts of your hot rod. A common part found on all high-performance engines is a harmonic damper (or harmonic balancer, as they are often called).

What is the difference between a 350 and a 383 stroker?
Premium Member. A stroker engine will have more cubic inches than a “regular” engine. A stock 350 piston travel is about 3.48 inches (88.4 mm) and in a 383 cubic inch stroker crankshaft the piston travels about 3.75 inches (95.25mm). That raises the displacement of the engine from 350 to 383 cubic inches.
