There are lots of V8 firing orders. Buick used 12784563 for years!

Ford is the one that has the firing order Right , It starts with 1 and ends with 8 . Some GM tech guys are also finding an advantage in changing the order from firing to exhausting . GM techs found this out in 2004 the ford guys spotted this advantage during Trans am racing back in 1968. If your not sure of the order find the number one spark plug wire on the distributor cap , follow the plug wire next to number one if it's
"3" you have the Marine or Windsor order . If it's number "5" you have the street or 302 order . If it's number "8" you are going the wrong way . Marine 302's had the 351 firing order before the 302 ho used it , For the first 302 ho Ford used a marine cam.Last edited by 417strokers; 10-10-2008 at 08:20 PM.
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
