I love it great points again from both Big bad and 55 ractor. 55 you brought up something i did not think about, so much HP on a "truck" old truck at that. Maybe I am pushing for a lot, wonder how much the 283 puts out now? if i could increase that by say 50-70% i would be a happy camper. Nd yes i replaced the drum brakes already with well yeah drum brakes but only because cylinder was out so for now remained with drum brakes all the way around changed out wheel cylinders all the way around switched out master cylinder and shoes all for about $370 installed and yes next step wouldd be discs. So I guess I should stray away from this predetermined 450RWHP wish for and focus on trying to find ojut how much HP i get now from my 283 and try to increase by 50% any guesses?
