Whoa! I'm getting these heads the frig' off! lol.blk91gt said:I agree, that 7.5 will eventually granade if you are making any sort of power. On my 82 GT I mannaged to explode the spider gears just launching on street tires in a stop light race (in my younger and stupider days). But you may as well run it till it pops.
D8OE heads were the generic v8 head used on everything from the 1978 "king cobra" to the 1984 GT, none of which topped 175 hp (flywheel). To give you some idea I went from 14.7s at 98 mph with unported D8 heads, Some generic 268 adv. duration cam, torker intake, 600 holley DP, shorties and 2.5 offroad pipe with 3.27 gears to [email protected] by just swapping to dart jr. heads and no other mods. (all on street tires). The car weighed in at just shy of 3000# with me in it.
