Thanks guys i do know the difference if i see it ,the problem was he wasnt specific,yr type etc,and i didnt see under the hood so i was kinda shooting in the dark assuming that it was ls,but then realized in my own mind it could be lt so thats y i got confused.its like tetoring 97/98 so i wanted to know both.if he cant do an older small block then he shouldnt be opening the hood,lol.but the funny thing is iii didnt realize if u had to pull the heads 98 newer [like ours]to change the lifters.
