give me some details on that cam man!!!

 

Here are some of the 847 specs. GM pn-12370847
234/242
.575/.595 w/1.6 rockers
112LSA

 

man you would have been better off just typing )*&^#+)@#^@#|*@&|#@#*&@*(#&@(*#& lol! my bad dont know much about the specs yet still learning.. will it work with my stock springs and lifters? or what?

 

Ur changing springs no matter what cam you buy. A GM847 is a very large cam. I would reccomend the CC503.

GM 846 Cam Specs

222/230
.543/.563 using 1.6 rockers
112 LSA

 

IMPO, from my experience... it doesn't get any better then the cc503 for a daily driver. Sounds awesome, and under 3k rpm (normal driving) you wouldn't know you had a cam. But when you get on it you sure as hell know. I put down 330 on a mustang dyno, an ran a 12.0 with all the bolt ons through an auto with a 3000 stall.

 

so what else do you need with it?? just a cam and springs? and will if give you enough hp to beat a stock LS1?

 

definatly enough power to beat a stock lt1.

You need the cam, obviously. definatly should upgrade the rockers, springs (with retainers and locks), hardened push rods (only like 36 bucks), would make sense to replace the timing chain. I ran mine on stock lifters with 120k on them.

I might have forgotten something, i just woke up and am still half asleep

 

not lt1 ab lS1

 

Sorry thats what i meant. LS1.

Hell, i beat on a modded LS1 several times with that set up.

 

You should replace your lifters while youre in there, and timing set. Also, if you plan on spinning over 6000rpms, youll probably want to upgrade the rocker arms... you dont have to, but its not a bad idea. Youre probably looking at atleast $750 in parts by the time you add it all up.

Its enough to run with a stock LT1, but a bolt-on LS1 will run right with you, maybe even faster... it depends on the car and the driver.

This is a list of popular cams that are being used in the LT1
Keep it under 230 duration. there are a few that are not accurate like the cc306 rpm range. but it should point you in the right direction.
Here are a few I would use:
GM12730846 --- 220@ .509/ 230@ .528 (1.5RR)--- 112 LSA --- 1800-5800
CCA-07-305 --- 220@ .510/ 230@ .510 (1.5RR)--- 114 LSA --- 1500-5500
CCA-07-502 --- 218@ .495/ 224@ .503 (1.5RR)--- 112 LSA --- 1500-5500
CRN-104227 --- 210@ .479/ 224@ .518 (1.5RR)--- 112 LSA --- 2000-6000 RPM
CRN-1449561 --- 216@ .551/ 224@ .551 (1.5RR)--- 115 LSA --- 1500-6000

 

What kind of power does the 847 make? It looks damn good. Does it lope a lot? Is it really streetable? What would be a good set of heads to go with them?

 

THe 847 doesn't even belong in this thread, as it won't pass emissions. But I've seen a car with that cam and completely hogged out stock heads put down a few short of 400 at the wheels through an A4 and a 12 bolt.
