Were the Vettes back then roller cams? If so that makes the break in part easy since you don't need to do much of one. What size cam is it, durration and lift? It isn't hard as long as there is room to work in a Vette and I can find that out easily if you guys don't already know. I have done uh, a few in other vehicles and it is no big deal as long as the cam won't be to big for you existing valve train. Most likely you will want to change springs which you can do with the heads on car if you have a compressor to hold the valves up. Since you will need springs you will need keepers and don't skimp on anything. Don't forget you will need intake gaskets and heads too if you don't have a compressor and for anything else in the way. There is more to it but it is really not that big of and deal and as long as the cam isn't too big your computer shoulhd compensate enough to make it drivable but proper tuning is the right way to go. Oh yeah, do you have new lifters? Also you will at least have to check you rockers for exessive wear and if you could afford it go with nice aluminum roller rockers so free up parasitic drag. Before you go any further, how many miles are on the bearings is also important since any higher lift cam is going to put more stress on things. If you aren't making good pressure wait until you can afford at least minor rebuild.
