M Body Coupe,
If you are going to compare LSAs, you need identical cams ground by the same company, with only LSA being different, such as this Isky test. The wide LSA cam made 3 hp more at peak rpm....but was down 19hp on the average.
Sure...if I have a bottomless pit stuffed full of $$$, and the time to allow me to do this...lol, which I do not!
My post was about a real-world experience of mine, with close-enough cams (heck, my biggest problem with even saying that is due to the flat tappet vs hydraulic roller difference).
