cam only lt1 "The magic wand for power"
I have been thinking of doing a cam swap from the stocker. I have full bolt ons for the most part and all free mods. I have been doing alot of reading old posts to figure out which cam will gain the most power with the stock heads. It seems to me some people feel that a larger cam like the gm 847 wont really benefit over a smaller baby cam. While some people feel a large cam is the way to go. Now im not at all concerned with MPG, and i dont care about how it sounds or the ammount of lope. The term streetable is different for everybody, but i just want the thing to idle at stoplights and not die. Emmisions are also not a concern. My question is what is the ultimate "cam only" cam? Track times and dyno numbers especailly are appreiciated, as well as a full list of bolt ons and mods. Im trying to seperate the cams the are hyped up from the ones that really preform. Thanks

Well I have had good success with the 219 219 525 525 LPE Camshaft but im also 383. but my heads are GM casting with bigger valves and a diffrent intake. not to much diffrence. I didnt want to jump on the band wagon with those other cams. and .. I Passed Emissions. !!

If I were to choose a cam for a cam only car id go...
all around cam I would choose the cc305 (220/230) or 503 (224/230).
If I wanted to make it more of a street/strip car and sacrifice a little driveability I would go cc306 (230/244) or GM847 (234/242). I would be a little afraid to run these cams on a stock bottom.
thats assuming you want to go off the shelf. for a little more money you can have a cam custom made to your setup.

Id go custom cam. Im also looking into a cam only set up and im gonna go with a Bret Bauer cam. Ive heard great things about him. Do a search for him here, lt1tech, or camaroz28. Hes very helpful and im sure he'll be able to give you what you need.

CC306. I pulled 371rwhp/358tq with this cam and unported stock castings.
Since then I added a 58mm TB and an MSD Digital 6+ ignition. After the electric WP and underdrive pulleys go on, I am expecting 390+rwhp.

No way a cam only LT1 is going to make 371

Well it did. Several people saw it too. Made 350/339 before the LTs, ported intake, and true duals.

I do have supporting mods. Here is a mod list, keep in mind that the slightly larger LT4 valves, ported intake manifold, 42lb injectors do absolutely nothing with stock heads.
11.8: 1 compression(from pistons, decking block)
JE forged pistons
CC306
Type Rs
Crane 1.6rrs
986 springs
LT4 valves
LE ported/welded intake
52mm TB
LPE CAI
42lb injectors
Pacesetter coated LTs
3" true duals w/ xpipe
I'll get the sheet up later, HP peak is 6100, thats when the heads stop breathing. Otherwise this 306 would make power way up there.

i agree go custom. either brett, or futural.
your going to make similar hp, but have alot better torque

im hoping to put down some decent #'s soon going with just an LE2 cam and stock heads. only thing i did with the heads was just a valve job, some port matching , and got em resurfaced. i ran out of $$ to get the LE3's so im just gonna see what it will do with just the cam. just wanna see how much power im giving up without the heads, but in a few months im definately getting the LE3's. also im going to see if i can break 12's cam only before i do the heads or the TNT 150 shot of juice is gonna go in.

This is a max effort custom Bret Bauer cam for stock heads. Similair to the one run by JonA here on the board. I will not release the spec of the cam in this add out of respect to Bret, but the buyer will get all the information I have on it. As said before it is a max effort cam so it is pretty large and has a very choppy idle. Cam is nearly brand new. Has maybe 15 minutes of idle run time on it. I'm selling because I decided to go with a completely different set up.

It appears that several of the above folks have good hp numbers with there combos. But some have ported intakes,oversize valves,port matched heads. I run a stockhead,stock shortblock,stock intake combo with a Custom Joe O cam. Iti made 353 rearwheel hp thru the mufflers with the belt on. No dyno tricks. It also ran 11.27 118.90 na in cool weather. Go with a custom grind for a max effort stockhead lt1. Frank95z
