Re: HEI Compression Test Question

What do the #5 and #6 spark plugs look like compared to the rest? Also, I'm sure you have already checked, but could you possible have those two wires crossed?

Re: HEI Compression Test Question

#5 & #6 spark plugs look like pretty similar to the rest....although slightly less carbon / black buildup on 5 & 6. I definitely have the correct firing order...no issues with wires being plugged out of place.
