i am looking at buying a complete 347 stroker from ford racing but heard nothing but bad about them . they make around 450 horses or so they say. i was also told i could bore my stock block to a 306ci , add heads , intake cam ,supercharger , etc and make the same or more horsepower and have a stronger motor. keep in mind i'm looking for 500+ rwhp. i was looking for some input from u guys on ur setups and what the best option is for that much rwhp and the strongest block possible ( i have a very heavy foot) for my application. any input greatly appriciated
