I have a decent running 304 with the T-19 tranny. I have added 36" Buckshots and would know like to tap the 304 for a little more power and RPM range. I would like to hear from anybody that has done this succesfully or otherwise. Any information on valve springs, cams, porting and polishing, head milling, 4 barrel intakes, headers, ANYTHING would be greatly appreciated. I want to build the perfect 304 IH. Also I have found a scout with a motor in a u-pull-it that would be a great head donor, but dont know how to tell if its a 304.
