The literature that came with my CompCamps XE274H flat tappet cam says to use 1 turn (or .045"*) of preload. Everything I am reading online says to use 1/4-1/2 of a turn. This cam says it makes power until 6,000 RPM and I would like to run the engine that high every now an then for short bursts. What are the pro's and con's of altering the preload?
* I checked the rocker studs and they are 24 threads per inch, so 1 turn = .042"
