Today I ordered the cam that gsgtx (joe) came up with on a thread started here called 425 cam question.If you remember it seems to cover a lot of the cam selections for the nailhead. The only thing that I changed was the lsa 110* to a lsa 112*. Tom T. thought it would help out with vaccum for the new disc brakes and it's an air conditioned car.Walt if you remember you ran that cam(Joe's)on your 2003 dyno program on your PC and thought it would be a great selection. That thread helped me in making this selection.This was the first part purchased in this build so stay tuned for more. I would like to start a build sheet for others to know what worked and didn't work for me and the cost involved. The comp cam and the lifters cost $285.00. Thanks for everybodys input.
