The C4's start at $700 without bellhousing or converter. That will get you a case fill built to take 400 -500 HP, select shift (lets you manually control first and second at any speed), with stock pan. It may be cheap but it is worth more. I don't pay my bills with the tranny sales so I can charge the lower amount.
As for shipping I have no idea - I might be able to get a quote if you email me your address and whether you want to supply your own converter and bell - it is cheaper to ship without them.
