@easpeed,
You could technically mount the radiator and jack the hoses side to side to go from your smallblock config to this big block (the inlet/outlet are opposite) but you really don't want to do that.
On the other hand, if anyone else is interested I will in fact take $250 shipped. I paid over $375 through a local vendor and I know they can be found online for less. At the same time be sure you're comparing to the big block with thickest core...
It's not doing me any good here and I'm not into stashing parts anymore.
