No problem.
When you start talking about building an engine from just a block, you have to remember that you have to buy everything..and after looking over some of the prices...
$2000-3000 for a rotating assembly
$500-1500 for heads
$500-800 for valve train
$600 for intake and carb
$250 for headers
$500-600 Misc. (oil pump, pan, covers , gaskets, etc.)
that's over $4000 in parts alone, then you still have to pay a machine shop, that bill will likely be a couple more grand, so now you are at $6000. And we haven't even started talking about all of the pulleys, mounts and brackets that you will have to buy.
Instead of building your 440 block,sell it and get one of these...
