Well I am getting all the parts together for my 383 build. I am wondering what would be better for the 383, an internal or external balance? I'll be using a 400 crank.

Any help will be greatly appreciated!

Mine's external. I suggest a Fluid Dampener.

My 383 was only externally balanced initially,
when I re-did it over winter, I spent the bucks and had it internally balanced, seems much smoother !!!

my .02

my .02 Do you remember what was the price difference, and was it worth it?

Eks,
If you are using a GM crank, it will probably cost in the area of $500 to internally balance it. I really do not see any big advantage for 99% of engines. If it is balance correctly, I also do not think it will be any smoother running either way.
