ok so after a week of failed attempts at getting ahold of comp i am fed up and looking into a crane stick, checking out jegs i am looking into the powermax series since i need emmissions legality, heres the specs on the ride.

stock shortblock
081 heads, ported to a 1205 gasket, blended bowls, 1.94in/1.50exh, comp srings, 3/8 studs, guideplates bronze guides
edelbrock tbi manifold
TES headers, 3" exhaust, high flow cat, unsure on muffler as of now
stock 2.73's looking to run a 3.73 or 3.5x in the near future,
all the basics, open element, ported tbi, msd coil, helicore wires, accel module...

I see the 2020 grind is recomended for tbi cars but manuals, how will this work out with the 700r4?

3rd block down, what you guys think, i want something thats gonna give me some wow, but it has to play nice with emmissions laws, the computer and KEEP IN MIND i am at 5280ft elevation......Any suggestions are appreciated, i have shows booked up starting the 19th and havent ordered the cam and some other small things to get her buttoned up, thanks gents

 

That 2020 is a real weak cam, I dont like it.

Personally, I'd look down 2 more blocks at the one that's in a block of it's own 270-109821. Now that cam I like. I hope you know how to tune your own chips, because you're going to have to do it no matter what cam you get with those ported heads. But that cam would be a pretty good match to those heads I think.

 

BUt that cam doesnt carry a CARB exemption and i gotta have that...it sucks

 

I don't think that if you get it tuned right anybody will be able to tell if you have replaced the cam unless it's got a rumpty rump idle.

(How'd ya like that tech term? LOL)

 

Dude,
You had trouble getting in touch with CompCams? Did you use our 800 cam help line? If you still want to go with a Comp camshaft, let me know and I can give you a name of someone to ask for.

 

I agree, I never look at the CARB exemption part. I Just look at the advertised/.050" duration, lift, etc, to determine what I need. Its inside the engine, they are not going to tear it apart to find out what is in it. Furthermore, 224/224 @ .050 had a very mild sound in my old 312.

 

Why not an LT1 cam???
----------
And they already have some closely tuned chips to run it too! It would probably be easier to tune with something thats already close to running it right!

 

I am not getting a LT1 cam because of the rest of the motor, as ken casey from burt said and he is the performance parts specialist, teh lt1 cam isnt worth the money for what i want to do, i WONT run a used or junkyard cam, never have never will, as he said its better to go aftermarket and get exactly what i want...I did get ahold of comp, yea that was short lived, the guy was kind of an *** on the phone, couldnt give me straight answers and just came off like he didnt wanna be there so i basically said screw you, called jegs and got ahold of a guy my dad used to race with back in the day, he's been there for a LONG time, as he said i can run a little more severe of a cam because of the altitude however with speed density and an auto trans i have to be careful, he reminded me of the same thing my dads always told me the guy with the narliest sounding cam is for the most part not the fastest guy, i am going to run the 2010 grind for now, crane cam power maxwith a roller tipped 1.5 rocker, as he said it'll be more than stock, match teh heads well and keep the tranny happy, as he said if i want to mess with it i can go to a 1.6 rocker down the road, i'd rather go small and figure out what its gonna like than go big and have to tear the motor down when it fails emmissions, we have the computer tests on the rollers and i know alot of guys that have had the same opinion as Fast355, and 90% of those boys had to end up running a smaller stick to get it to pass, i'm not planning on ripping it down again for awhile

 

wow i must have wrote down the wrong grind #, i'm exhausted but looking at cranes site they list the 2010 and reading the specs that doesnt seem right, its for 81-87 cars and 97-95 trucks which if i remember correctly is a non roller cam, i'm not sure what is going on with me right now

 

What are the specs on the 2010? Because you say you don't want to run an LT1 cam, but that first cam you listed, the 2020 is smaller than the LT1 cam.

edit: posted after ur last post so nevermind.

 

Yea thats what I was thinking about when I suggested the LT1.
I know you probably researched the cams, but you probably wanna keep it computer friendly. If not, than just ditch the TBI and I might have a guy that can pass you on the emissions. PM me! Thats what am doing!

 

Our emissions test are on a loaded dyno as well. I had no problem even making my L82 (224/224 @ .050, .450/.461, 115* lobe seperation, 107* intake centerline) cammed 305 pass easily. The key is tuning.

The head swap ALONE will make you fail a dyno smog check, IF your ECM is not tuned correctly for it.


CraneCams

 

WOW how come i get the idiots on teh phones, called crane, guy was an ***, had to fight to even get the specs out of him and the cam is tiny 184/194 at 50, 384/407 with a 106* seperation....450 bucks

Called comp, sat on hold for about 40 minutes got ahold of someone who sounded different from the last guy i talked to, anyway this guy recommended a PN 08-300-8 specs go like this
206/210 at 50
450int/480exh
112x4

Its pricey 309 he said it isnt emmissions legal, none of theres are but its for the computer controlled cars, said it should pass safely because of my elevation and will work with the tranny and vacuum no problem, not ordering just yet, what you guys think?

 

I'd say it's so close to an LT1 that it would be a waste of cash. LT1 would be almost the same thing for cheap

 

I would look at the GM ramjet/HT383 cam. It is a stop light brawler from idle-5,500 RPM, computer friendly, and great fuel mileage.

 

Buy a new LT1 cam than!
From what you are describing LT1 cam would be a very good bet for the LO3. If you want a new one from a perfomance place, it would probably have the same or very close to, LT1 specs. However, you would be paying way more. Its a 305, make it fast, but don't go too far, cuz it is a 305 after all. Use the money for better springs and rockers or sumtin'.

Laters.

 

I dont need to worry about good springs, these heads had a build price of 1400 bucks, everythings dollar on em, best of the best i just so happened to be in the right place and the right time and got em dirt cheap

COrrect me if i'm wron gbut isnt the lt1 only run like a 398 int lift?

 

205/207 @ .050", 279/276 advertised, .447/.459 w/ 1.5 rocker, 115* lobe seperation angle.

 

Really? what the hell was i looking at then....hmm, i'll have to give my local gm a call and get a price, jegs runs that comp i'm looking at for 244, opposed to the 309 comp told me

 

Called my parts guy at burt, he can get me the LT1 cam for a mere 404.68
Yea i think i'll be calling up jegs and ordering the comp, for 244, again lt1 cams are cheap but i will not run a used cam and the new ones are pricey.....i'll have to find what i was looking at that showed the lt1 as a 398 lift though huh

 

You do realize that there is no problem running used roller cams.

 

Yeah man, i hate to see people throwing that much money at a Comp cam that has the same specs as a cam they can get for under $50 all day long! Seriously, find a low mileage one if it makes you feel better, roller cams do not get wear patterns on them and don't have to be used with the same lifters. There is NO problem with running a used roller cam.

 

:

Inspect it carefully, then stick it in. Save the extra money for suspension upgraded to hook up the new power.

I paid $40.00 for my LT1 cam, it looked brand new!

 

well i'd rather spend the extra and have that piece of mine, we've been building motors for years, my dads put more cars into the 10's than you can imagine and its one of those things even with rollers in montes and whatnot we dont use used cams, ontop of that you cant even find 4th gens out here in boneyards or getting parted out, adn on the rare occasion the motors already gone or really high mileage

The way i figure is i'm going to have around 1500 in the motor when its done, i just put on a 2k dollar suspension a few months back and have well over 5k into paint and body....whats an extra 250 bucks ya know?

 

I run the 2030 in my 350 is idles smooth and gets decent gas milage. . . passes emissions too. I've got some 1.6's going on this week though. Should waken it up a bit with those Trick Flow heads I have on it.
