I have a 1970 GTX with a 1968 440 engine in it. The engine has been into before I bought the car. No ideas on the specs at all on it. It doesn't seem too radical. I decided to check the condition of the timing chain on the engine. I lined up the timing mark on the balancer, checked the dist.( pointing to #1 on cap) and ripped it apart. The chain had a lot of play it it so i decided to replace it with a roller setup.Now my problem. The marks on the gears were not lined up. the cam gear was at 12:00 and the crank gear was at 12:00. The info I can find says the marks should be lined up at 12:00 on crank and 6:00 on cam gear. :confused:??? Would the engine even run with the cam 180 degrees out?? It ran okay but had a detonation problem which started me down this road. One of the senior techs at the shop I work at said that it should be timed like that. He said to line it up with the casting bump on the block just above the timing cover like it was. Any Help would be appreciated. Rich
