Well I just picked up a 74 260z, I bought it from a repo yard, and the forsale sign that was in the car from the old owner claimed it had an L28 block and an L24 head. Now I'm not sure how much truth is in that but it hasn't been ran in a while now. I can smell gas, but it smells kinda funky, it has no air cleaner or anything of the sort on the end of the carbs. I can't find any wiring diagrams for it to see if the wiring is good or bad. We cranked it over and it almost wants to start, but won't fire. I know it has spark, I just put new gas in it so I know the gas is good......any suggestions or some good pics of a motor so I can see how the fuel lines are ran and what not???
