thats kind of the way i was leaning, the 5,000 excludes labor that is only for parts, i want to leave the engine reliable as it is my daily driver, but i have never rode in a car with the internal mods like springs, valve, pnp, so i was curious to their performance, because a lot of guys seem to agree that this is a solid build way to go, what do you think about new camshafts? thanks for your input, it helps reassure myself that i want to go this way
