HELP! 418W problem during initial start-up

[REPLIMOD #17]

So what did the cam card say the firing order was? Curious about the outcome of this caper. Been there done that..............like to see him lick this problem.

After beating my self up for the past couple days. I decided to take a step back and start from scratch. I had myself so convinced that it was a more complicated problem that I overlooked some of the basics.
I spoke with my engine builder and he confirmed that I was using the correct firing order (351w).

So I went to the shop for a long lunch break. I fired the car and began to pull each plug wire one at a time. Come to find out that I had 2 plug wires which were not functioning right... who would have thought it. They were practically brand new, but they had been sitting in the shop for over 3 years...

I took the car for a test drive, and I'm very happy with the results. I've still got a few bugs to work out but it's nothing major. The car has lots of power, and traction is tough to come by even with 275/40/18's...It should make for a fun ride

What year car do you have with those wheels and tire sizes?

And I am glad you got it solved...
