Which would be teh best way to go about balancing my motor (383, 5.85 rods most likely)? does the lt1 need a specific one or can either be used?


Pros and cons to each option would be great!

 

It is my opinion if your building a stroker your new rotating assembly should be internally balanced. Then neutral balance the flywheel.

 

what about the balancer on the front? what happens to that if its internal balanced?

 

Actually it is a harmonic damper and is neutrally balanced, except in some rare cases. If there are no holes drilled in the back of it, it's neutral. If I were going thru the expense of building a stroker, I would get an aftermarket damper.

 

It is very difficult and expensive to internally balance parts that are bought seperately. I understand the Callies Dragaonslayer crank is very easy to internally balance. Talk to the guys at Nu-tek. You will be much better off buying a balanced kit. Several good ones are available. Scoggin has them, Nu-tek and Golen are some others.

 

i bought my crank, rods and pistons speratly. took it to the machine shop and picked it up the next day balanced and all

It depends on the parts you choose on how much mallory will be needed to internally balance the rotating assembly.

For instance, my Eagle rotating assembly internal balanced no problems.

My Cast GM 400 crank which I had turned down for a 383 needed a ton of mallory to internally balance. So it cost more. External balancing these parts would have been a better idea

Just a coupel of examples I have dealt with.

 

On the LT1's it's both internally & externally balanced from the factory. The front of the crank is internally balanced and the rear is externally balanced.
But it's always better to internally balance an engine, if you do remember to take the flywheel/flexplate and your hub/balancer to the machine shop and have everything balanced together.
