not sure what is worse.. the post that was obviously made without doing a search.. or the useless response? yea yea.. they didn't use the search link.. but posting a couple links referencing to similar topics would have at least helped them on their way a little.. and wouldn't give them the mindset that people on this website are rude.

Red_1989_GTA, what does your engine setup look like? would probably give us a better idea of how that cam would work for you. the more detail the better. also welcome to the site! hopefully you stick around and learn a lot from it.

Re: Anyone using XR276HR cam by comp cams?

It is somewhat of a hot street 350 or tame 383 camshaft. It is on a 110 LSA so the idle in the 350 may have a lope depending what RPM you set it at for idle. In a 383 it will just sound like a car with nice exhaust. Probably have some good midrange power in a 350. But you really need to post what you have or are building for people to say what they think it will do for you. Good or bad match.

I had it in my L98. Also had AFR 195's and a HSR intake. Engine made power all the way to a little above 6000rpm. Nice choppy idle too.
