Were you getting a misfire cel on cyl 4?
No! I couldn’t believe it when I pulled that pushrod out. It has has a faint lifter tap since I bought it nearly 2 years ago. The only thing I noticed was complete lack of power. I just assumed it was the gearing (3.08). Really expecting the cam and all the extras to wake this hoe up.
