i bought a new/rebuilt engine for my truck from a local engine rebuilding place where i live and the engine they gave me has a diffrent firing order than my orig engine and i want to know if i have to change any thing to make this engine run correctly change any thing like the ecm both engines are 302 roller engines and supposedly i have the lightning cam in this engine they sold me i took the orig firing order in with me when i went to get the engine so i still have no idea how this got messed up

my origional engine firing order was1-3-7-2-6-5-4-8

new engine firing order is1-5--4-2-6-3-7-8

thanks in advance

Welcome to FTE . The 94 motor you had in your truck with the 13726548 was a roller motor , sounds like the motor they gave you is non roller 15426378 . The 351-302HO & 94 & up 302 should have the 13726548 firing order , ...Lew
