I have a stock bottom end. I spin my hotcam kit to 6500 rpm, and thats where I kind of draw the line. I am seriously thinking of a head and cam swap this winter, and my cam choice is the gm 847. But, are these cams available with different lsa, and what lsa would I want if I dont want to rev to 6800 or 6900 to get peak power. Thanks for the replies.

TTT...Any advice is appreciated.

GM 847 is a GM Performance Parts product, so I don't think you can get it on a different LSA. 112 LSA isn't too bad though, it should be strong with a nice set of heads.
