i agree, forced induction is about the only way to get a 525 to 300 and still have it streetable, with enough money 300 could be done without a blower but the power band would be nasty and very traffic unfriendly plus it could not be run with the factory auto tranny. as for a 535 didn't pat p get over 400 outta a stock 200+k mile m30 long block
