Trying to understand cam overlap and boost
#14
Well the main reason for wanting to switch is because I would have to run a large pulley to keep boost under 12# at 6900rpm. It doesn't have much low end now. So if I swap for a cam that has better low end, maxes around 6500, then I can pulley down to run 12# at 6500 and boost will come in sooner.

Stock48 just sent me a 215/224-112 isky cam for a silvy ss I'm working on, lq9 with a d1. He spec'd a similar one for my old tvs1900 truck that worked really well. His cams are a little different from the typical blower and turbo cams, but they have all made excellent power, his truck speaks for itself... Personally, I never liked the huge lsa, big negative overlap cams anyway, they seem to be soft down low and have no chop at all. All personal preference though, and honestly, 10-15hp difference in a forced induction build isn't as important as having a cam that makes your truck sound and drive how you like it.
