GM 847 or CC306?
From the looks of it they are pretty equal..... And i will be running it on stock heads for a while.... probably about 6 months..... Until i can have the money to do the heads..... BUT i might have the money to do both at the same time this summer.... what do yall think??? Any opinions welcome!

I'm pretty high up on the gm847. Even on stock heads, I've seen better #'s from that cam. They aren't really equal. The duration is pretty close, but the 847 has a much larger lift #'s.

atjlar has gone 11.9x or so with a 847 and stock heads... (launching it pretty hard)
and cc306 is like the limits of a stock head imo
i'll be putting my cc306 tommorow... i'm on stock heads as well, i'll let u know what happens
i did see a dyno of a stock head cc306 with bolt on goodies dynoing like 350+ tho

i have the cc306 with ported heads and i want bigger, wish i would have gone custom grind or 847...

Yeah, the 306 with ported heads is remarkably mild. I dont even notice it is in there anymore with daily driving.

GM847 and the 306 are no where near equal...
306 compared to an 847 is like comparing the 306 to the hotcam... Even though both the 306 & hotcam are both wimpy cams Hell even the 847 is still kinda small in my book
DEFNIATELY go with the 847 cam BUT with stock heads :blah: I would go the 306... Just cause dude you can't be trying to slap on BIG cam's on STOCK HEADS

Oh wow. There's not much difference between the cams.
306 = 230/244 .510/.540 112lsa
847 = 234/242 .575/.595 112lsa
This thread is obviously going nowhere.

the ramps are alot diffenert between the two and also the valve timing is diferent.
and i bet if you do your reasearch on the 2 you will find alot of difference between the two. if you were going to spray it the 306 is better. because the
personally if i were to buy a off the self cam it would be the 847 on a 110 over the 306 anyday.
here are the spec cards.

How is 115 MPH with stock heads slow??? , just because he didnt launch at 6k rpm on slicks doesnt mean his car is slow.
