ok, the other dayi pulled the valve covers on my 85 Iroc, hoping to find the cource of a rattle upon acceleration under load. From what ive read, here and other sites, most likely its loose rocker arms, several were semi-loose so i figured id adjust them all again and see if it solved my issue, BUT now i have another issue. I set the motor to TDC according to the timing pointer on the motor and the rotor points to where #8 terminal is on the distributor. I didnt touch the distributor at all, i just took the cap off. From past experiences, TDC should put the rotor pointing at about the back drivers side of the carb, this is now pointing at the back passenger side of the carb. So right now im stumper as what to do. The car ran with how the wire were currently setup so im not gonna start moving wires around. The other thing that i noticed was that the timing tab is in a different spot than where im used to it being on previous SBCs ive worked on. The others you could see the tab right next to the power steering pump, but on this motor, you have to look down through the middle behind the water pump. If the Tab was where im used to seeing them, it would put the rotor at #1 terminal and then everythign would be fine. What do you suggest i should do?
