Shawn;

I can not remember the magazine or month,one of the monthly Mustang mags though,they took a Ford crate 392 stroker and did a bunch of dyno pulls on it. They got around 450 with it as it comes from Ford,then they put a set of AFR heads on it and made a few minor changes and got a tad over 500 hp,around 510 or so if I remember right,all on premium pump gas....

A used or "seasoned" block as some engine builders call them are fine for street and some racing,if you are building a strictly race car I would go with an SVO or Dart block.... Some enigne builders actually prefer used blocks to new blocks as they have been heat cycled many many times and the block has "settled".

If you are looking for a 500 hp smallblock stroker,then I think the 392 strocker with the AFR heads are any top shelf aluminum heads are the ticket for 500 hp and this can be done all on pump gas....
