ok folks in need of some advise, its spring time and i'm getting ready to work on my engine. i have a 350, an wanting to throw in a small cam. never did a cam job before, but its alot of things i never done before an was able to do it. i have the books that tell me how to do it. it doesn't sound hard just seem like tidius work. i just dont want to mess up the engine. also plannin on installing a double roll timing chain with the cam. i guess my question is should i pay a shop or just do it. an wat other small easy modifications can i to my 350 while its out of the car.
