If he could he would.!
I just don't see how he can't get that hp. ?? i have a 440 stock stroke .040 over stock crank & rods with cheap kb pistons & Indy SR head with a very mild port job M-1 intake no port work at all & 950 carb with a solid lift cam 282/292 & 540/559 lift with 1.6 Indy roller rockers & TTI headers and i am making 580 hp & Tq at the same & i had it Dynoed so its not a guess HP motor.!

*** So you are saying a hemi with better heads & bigger Valves better rod & pistons and a roller cam set up and head work & intake work with good headers won't out do mine. ?? ***

I would tend to think it would be pretty hard to get 600 - 650hp out of a stock stroke street hemi while still being streetable and able to run on pump swill. A factory race hemi grossed out in the 550ish range with headers IIRC.

I think your friend needs to;

- pony up and stroke it
- give up being streetable and pump gas friendly
or
- lower hp expectations to something more reasonable; maybe 500 - 550hp
