Not sure but I think you can pull the cam after removing intercooler and radiator , and AC condenser. Of course youhave to remove the rockers and pushrods. TST Products is in Columbus, IN, 342-6741. They may have the cam removal tools. That is the biggest hassle for the home mechanic. You could make the stuff yourself from 1/2 inch wooden dowel pin pieces, with a slit cut 3/4 inch deep on the end and the end chamferred so it can be driven into each lifter. Hold the pins up with clothes pins, and shove in a 2. 5 foot or longer piece of 2" exhaust pipe to replace the cam while doing the gear case change (in case a lifter tries to drop).
