Good source for Dart/World Block ?

[DRJDVM's '69]

I'm in the market for a Dart Little M or a World Motown block ( for a new supercharged 406 project).

I've looked at Summit, Jegs, Herbert etc as well as an internet search..... found a wide range of prices..... and a wide range of shipping prices (some as much as $250 just for shipping )....

Anyone have a good, relaible, reasonably priced source ???

I'm alittle apprehensive ordering from a random internet company just because they have the lowest price. You never know who you're dealing with.

I'm in Nor CA, so local would be cool, but then I have to add sales tax too...
