It would have to be pretty radical for 500rwhp your heads, intake and injectors wont even get you close. It with out doubt would have to be a race gas motor and spun upwards of 8000rpm, and aftermarket block.
 
u would need a high compression motor to see 500rwhp on a NA 347 stroker and better parts than u have listed. 400rwhp is attainable on 10.7:1CR and ur combo above with the right lift and duration cam.
 
My 11.1 comp. 364 makes about that (500 hp) its a 347 with a 4.125 bore. (364) I have a set of afr 205 and spin it to 7,600+. If you want N/A 500 rwhp go with a 351 based motor a nice 408 could pump out that power. RNH PER. did one he// of a nice motor for me have about 75 n/a pass on it this year running 10.70-10.90 and about 25 150 shot passes with some mid 9 out of it
 
It would have to be an unstreetable compression ratio and some high-revving to get 500 RWHP out of one. It isn't impossible, but not very realistic for a daily driver, or better yet, street car.
