The LS block I have had a Vtec head already matched up to it, in which my boy has.... As we speak I saving up for a head and other various parts. I have already managed to get pistons and rods but 'm not gonna tell all my secrets just yet... As someone mention to me and herr on this site, I need to focus on getting the vtec working right first.... Besides I have found an elecltric water pumps its kinda pricey but hey, I had one before and there was a noticable diffrence.... I love assorted goodies I just dont like paying for them all....
