Hey, I have an 88 GT and just finished installing F303 cam gt40 iron heads and gt40 intake. The started fine, so I took it out for a test drive. It had no power so I brought back in to check the timing. Pulled the distributor out so that I can zero the balancer to TDC and installed it again. I couldnt get the car to start. I thought that maybe I was 180 degrees off on the distributor so I spun the engine and flipped the dist rotor and still nothing. Now im thinking this isnt right because I just tried it both 180 degree ways> I check fuel and spark and I have those. I flipped the dist. again to the way it was the first time and the car started. Took it out for a drive but still didnt have power so came back in. Shut the car off and it didnt restart, all if did was crank. Had spark and fuel again, but no start. After doing the above things AGAIN, (after like 2hrs) the car started again. I went for a drive and since the car didnt have power again, I decided to adjust the timing on the street so I don’t shut the car off. I turned the DIST wayy off and the car had power all of a sudden. It was soo much that the marks on the dist were gone. But it had power. Thinking that the timing is still way off, I went back in to adjust timing and now I cant start the car for anything. Just cranks whether its 180 one way or another. Still have spark and crank. Im thinking that maybe I degreed the cam? I don’t know. I got the Ford racing double roller chain with the 4 marks on it. Someone please help me out here.
