We have used MANY smallblocks from cup shops,,,most notably Roush/Yates engine shop,,we generally paid around 38k for good smallblocks, basically 358cid, they would dyno at 780+hp and didnt run until they turned 8700rpm,,,and would turn those rpms all day long,,,,so its doubtful what this guy is claiming to be a 500 hp motor,,with a 30 to 40 k motor cost is true. Even Clemens house of power in S. Carolina isnt that pricey for a 500hp mopar sb...... just my two cents
