700HP 383 Buildup

Nathan, if that's truely what you need,then i would suggest selling the parts and starting over. First, no 383 will make that kind of power on pump gas without some sort of boost. Second, stock rods will not hold for very long under that kind or strain, nor will the pistons. It doesnt sound like you have a lot of experience making this kind of power, or the other things that need to go with it. It takes roughly twice the money to get the same horsepower from a big block mopar vs. small block chevy, closer to 3 times if you also need reliability, and some sort of boost. You need to do all the same work, I'd suggest a 496 kit, put into a 440 block, and run that with Indy EZs or Bulldogs. Edelbrocks would also work, but make less power overall. Any of the 3 will need to be "cleaned up" to run well. Fiure a safe bet of $8000US, not including shipping, fuel system, a transmission to hold it, the Dana you'll need..etc etc. etc.

BTW, a 440 with decent compression, ported iron heads, and a solid cam will run high 10s with the right stuff in it, and I'd be surprised if it made 550 hp.
