Was thinking of getting the 503, but have been advised to go with the 306. Just throwing it out there if anyone has one.

 

CC306 and GM847 are fairly similar cam's. My buddy has one for sale here: https://www.camaroz28.com/forums/sho...d.php?t=838823

Some debate: http://ls1tech.com/forums/lt1-lt4-mo...-vs-cc306.html

I run one in my setup that has stock heads with 1.6rr and drive it all summer on the street. It runs just fine contrary to what everyone that doesn't have one says.

 

Thanks man. Actually went different route. Getting xfi 280. Looking at install in several months, in mean time start planning the route im taking the top end to accompany it.
