I am planning on starting the bottom end of my motor in my z24 soon. Im thinking about either building a 2.3 or doing the stroker for the cav. Im undecided but I do have the oppertunity to buy a 2.3 out of a 93 grand am for $400. I havnt talked too much to the guy yet but he said it runs fine and that he will pull it out of the car and bring it to me so im thinkin $400 sounds good to me. What casting head came on the 93 motor? Also im assuming that its a Lo motor which is fine, did they even make an HO in 93?
