Re: LQ9 In a 1970 Suburban

Its a 6.0L GenIII LSx motor. Probably the highest output truck motor of that generation...correct me if i'm wrong. It's just like the LQ4 but with flat top pistons (not dished) so it has a bit higher compression and, therefore, rated for more hp/tq. Iron block, aluminum heads. Was found it the Heavy Duty line of GM trucks and in some Cadillacs.
