Gm847
 

What do you guys think about putting a GM847 cam in a supercharged 355 with 12lbs of boost? I have a cc305 cam in my engine now with 8lbs...its ok, but i want more out of it so im stepping upto 12lbs and thinking about a forged 355 and i need to put a cam in it..Any help will be appriciated.

talk to comp cams about a blower cam for your setup....

yeah i did earlier today and they suggested the exact same cam i already have....i was hoping to get something different with a bit more lope...lol

My custom grind is similar to the 847 just more exhaust duration and a wider LSA. Works pretty good when the car runs.

Comp's NX276HR (224/236) is a popular blower grind. I ran one in a stock LT1 S trim setup and it worked great.

do you know what the rpm range is with that cam?
