Damn you are old. lol. My first one was on a 1 year old 69' chevelle ss 396. Bored and stroked with a twin pack. Had to wait until the warranty was up. Rememeber, 12,000 or 12 mos. what ever came first. I don't know how many hours and dollars I've spent since then but, it's a lot. I'll bet my wife knows what I've spent though. lol!
