72 turn key 340 complete carb to oil pan

So you are selling your 340 so you can get and build a 340? I was following your other thread.

You have a 340 now. Just bump the compression, slip in a modern cam and you will be at or over the power level of a stock 70 340 for well under $4,000.

I guess I don't understand why you think you need a different 340 for your build.
