I have an 86 454 that is stock aside from headers, and performer intake along with Holley 670 carb. The truck was given to me after sitting for 8 yrs. I was able to get it running with minimal effort, and for the most part has done pretty well. It was plagued with a rusty gas tank which caused me to park it for a couple weeks. Previously I had notices the occasional pop from the exhaust. As soon as the tank was replaced and fired it up it had what I thought was a miss. I traced it to cylinder one. The compression test came up with 60 psi on one with all others being 150. Any guess why it's so low?
