Installing the Camshaft

- I installed an Eldebrock Performer Plus cam kit (cam and lifters) that I had purchased earlier this year. The supplied cam lube is red and used to coat the lobes. I used Permatex Engine Assembly Lube to generously coat the bearings.

Long bolts in cam gear and blue string to guide tranny end of cam into place

I'm fortunate enough to have a good friend Mark who provided expert advice and tips on putting every thing back together. We used 2 extra long bolts in the cam gear bolt holes to help guide the cam in. Mark's cam installation tip was to use a string on the tranny end to guide the cam into position. It's simple and works very well.

One step forward, two steps back. Found out that the jumper that selects whether the tach is for a 4, 6 or 8 cylinder engine was not making good contact. The engine seemed to me to be idling about 600 rpm but showed 1200 rpm. Reseated the jumper and it indicates 600 rpm. Unfortunately, it means that I broke in the cam at 1000 rpm not 2000 rpm. Had to break in the cam again at the right rpm. Hopefully, I haven't damaged the lobs. (Quick note: two years later and the cam is fine)

The reason for the high rpm break-in period is that the cam lobs are lubricated by oil splashed around by the crankshaft. At idle, there's not much oil splashed around but at 2000 rpm there's lots. The cam lob's will create a good wear pattern with the lifters. That's the reason for the cam break-in.
