Re: mind bender 5.0
The H.O. is not determined by the heads or intake. It is determined by the cam. The H.O. cam uses the 351 Firing order (otherwise known as the H.O. firing order in a 302) and it is a roller cam(a cam used with roller lifters).
So my question would be, Do you have roller lifters in this engine along with a roller cam? You need to determine if you are running the correct firing order to proceed troubleshooting other things.
