After 8 years of not owning a pickup I finally found one that I wanted.. Its a 1988 C1500 with a 454.. The guy I bought it from said the motor came out of a 1988 C3500.. I know the timing should be set at 4*BTC but the truck won't run at this setting.. Backfires through the TBI.. I set it back to where it was and this is at the highest mark.. Can't read it but I'm guessing the mark is around 12*.. What would cause this to happen?? I changed the plugs, distrubutor cap and rotor.. The only thing that I didn't change was the plug wires.. All looked fine but I did have to replace two because they were burnt from the headers but this didn't change anything.. The truck also feels like its not getting enough gas.. I would like to put a carb. and intake on.. What would ya'll suggest in this department.. The truck also has headers w/out cats and flowmaster mufflers with dual 3" pipes from the headers out.. I'm not looking for a race truck but I would like for it to run right.. Thanks for the help...
