In the case of an internally balanced motor, the lower rotating assembly inside the motor (pistons, rods, crank and so on) is balanced independent of any external parts. In an externally balanced motor, the converter and/or harmonicbalancer are required to ensure that the engine does spin out-of-balance.
internally
it is definitaley internally balanced
yes a 2.8 litre Chevy is internally balanced
no, it is externally balanced
all 1995 350s are internally balanced. still need harmonic balancer though
One way to determine if a Chevy 350 engine is internally or externally balanced is to check the harmonic balancer. If the balancer has counterweights welded to the outside, it is externally balanced. If it does not have any counterweights visible on the outside, it is internally balanced. It is always best to consult the engine's specifications or a reliable source to confirm the balancing type.
YES it is.
No, it is not recommended to mix an internally balanced flexplate with an externally balanced crankshaft and balancer. It is important to use components that are all balanced the same way to ensure proper engine balance and avoid potential damage.
No. The 400 is externally balanced, the 350 is internally balanced.
No it will not work. It will bolt up but 454 is externally balanced and 305 is internally balanced.
No. The 454 is an externally balanced engine, the 350 is internally balanced.
It is internally balanced. The 400 small block is the only Chevy engine that is externally balanced.
