A couple questions about supercharging a 440
My opinion, build the best bottom end you can afford while you have the engine out. It doesn't have to come out later on for upgrades. The best bottom end for your plans may very well be what is in there now. In my case, my builder put in a used Callies crank from one of his Top Fuel friends. Your cam sounds fine. Not sure you'll get the lopey idle you want because the blower will tend to smooth it out. Doesn't sound like you want to build a ragged edge race engine. 600HP sounds easy with what you are describing. In my case I could not keep the wiper motor in with the 8-71. We had to recess the fuse plug box. Had to take out the puller fans out and put in pusher fans in the front of the rad. There just wasn't any space left to do otherwise. Used a front engine plate instead of mounts. My engine has CNC'd Edelbrock heads. They will be fine until I can come up with some scratch for something more exotic - no rush. I think cast iron heads would work fine, but that they would tend to be a bit of a heat sink after awhile. I put in a 55GPM Mezerie water pump, no t-stat, and a 3 core aluminum rad for cooling. Maybe try and figure out in advance what size pulleys (teeth) you want to run. Pick what carbs you'll be using.You'll probably have to upgrade the fuel pump, regulator and supply line. You'll probably need a new throttle cable.Transmission may be a weak spot, depending how often you see how much boost you can make. Deep sump, rear mounted cooling fan for trans fluid. U-joint upgrade. Check out the differential. You'll need to modify the hood (if you are going to use one). Nice open exhaust system. You can go without doing any mods, but I encourage you to think of it as a package deal, not just slap it on and hope for the best. No matter what you do, like Lustle said, you will make power and I think 600 is a conservative estimate. You will be amazed.
