I had a buddy who put his sparkplug wires on backwards, I mean he had the right firing order but put them on clockwise instead of counterclockwise. Just a thought. Simple but easily overlooked.
Like Russ Said Cam Firing Order Might Be Diff. 351w Firing Order Is Diff. From Early 302, Check Cam Grind For Specs.ALOT OF CAM MAKERS GRIND THEM TO 351W FIRING ORDER
If the cam is ground for a 351, I'm screwed. I'll call Edelbrock with their part number in the morning. Thanks for all your help. You guys are first class in my book. I'll post the outcome when I get it running. Grant
Easy There, 351w Firing Order Is Great , They Say It's Easier On The Bottom End Becouse Of The Order Change, All You Have To Do Is Rewire The Dist. To 351w Firing Order!!
