Figure 45

Figure 45. This is the new camshaft. It is a Brian Tooley Racing Stage 2 Truck Cam. This is probably the most aggressive cam to put in without putting a higher stall torque converter in the transmission. Calculated valve lift with this cam and the 1.8 ratio rockers is 0.585.

Figure 46. Here is the cam going in, lubricate it thoroughly and go slow and carefully so the bearings do not get damaged during the install.

Figure 47

Figure 47. Here is the cam almost all the way in. A couple long bolts from the local hardware store do the trick for a handle to maneuver it with as it is being placed in the block.
