On my 95 silverado 350 TBI, the lifters are needing to be replaced. I figure since I am in there, I might as well start changing some other things, and in this case, I figure I will put a new camshaft in there also. Has anyone chenged their camshaft and if so, what are some things to expect? I have done work on my cars and truck before, but nothing this in depth so far. I guess I am a little cautious because I have to remove so much other stuff like the radiator, fan, timing chain, and such. Also, with the timing gear, should I replace that since i have it off or should it still be fine? Does anyone have any experience with the gear drive timing setups? What are the pros and cons of it? I am thinking are they worth the extra price for the sound and strength? Also, do they add any more power and how much drag do they have compared to a timing chain setup? Other than the sound, I am dont know much about them. This is the first of a list of planned upgrades. Thanks, Brian
