588 big block mopar

I'm not trying to be rude or condescending, but asking "why bother building something that big, what are you trying to accomplish" is like to asking why bother modifying your car. We could go all through this forum and ask questions like "why bother installing a bigger cam?" or "why bother building a stroker?" or "why bother installing cnc ported aluminum heads?" Why bother asking someone why they're doing something to increase power in their car?, is that not what most of us here are trying to do???

Those are the questions that any engine builder will ask a customer that says they want to build a 588 inch engine. It is a weird size so any engine builder will want to know why that size? They'll also want to know what are you trying to accomplish and they'll want to know how big the budget is.

There is nothing magic about 588 cubes. Pro Stock enignes make a lot of power from 500 inches so if someone wants to go really fast just buy an old Pro Stock engine. A smarter question for the OP to ask would be "what is the easiest way to make 1000 hp" or whatever it is that they are trying to accomplish. Since the OP never said what they were really trying to accomplish it is a pointless discussion.
