How hard will it be to put a cam in my lt1 while its still in the car? What cam should i go with? Im kinda likeing the GM847 or the CC306.

 

not too bad of a job. there's writeups all over. 847 and cc306 might be a little big for your application. Guys run them in stock motors but unless your using the powerband the cams were designed for, your wasting your time. Go with something more useable. A call to crane, comp, isky, etc. will get you some good answers. Lloyd Elliot or Bret Bauer can help you out as well.
