Ugh it was been a long day. Plan was to swap out the stock upper and lower with my GT40 setup i got off ebay. The guy used it on his wifes 87 fox and was switching to a carb setup. It was off an explorer originally. Ok, so i tear it all down, do it right, swap out the lower and upper....definately went back together faster than taking her appart. Ok, i get everything together and crank her over....crank crank crank crank crank crank........bang! back fire. Ok so i'm thinking the timing is way off. I had to pull the distributer off to get at the lower intake. Before i took it off I set the the engine to the zero mark on the crank indicator and the distributer just came right out. Now i don't know what to do. I set the gun on it and and got the line to match up and still nothing. It cranks and sometimes when you stop, the engine kinda like half runs for a second. I think the timing is wayyyy off, but how do i fix this, i'm not really that great with distributers. Any help would really be appreciated, the car is no wat my buddy's work and i'm going to have to get it out of there tomorrow. Thanks guys!!
