would this cam work well with my combo, how much eprom tuning would be necessary for the car to be able to run?
http://www.jegs.com/cgi-bin/ncommerc...911&prmenbr=76

 

well it depends on what year your motor is cause that cam is not a roller. if you have an 87 and newer car then the block is roller and u need a roller cam. i was lookin at the same cam. theres a guy named zepher around here who has that cam in his car its a 305 tpi. it sound awsome!! i am lookin for that cam in roller. go to the tech bored and look for a post by zepher he will have a video of the car. if u find this cam in roller let me know. thanks

 

I like the Crane Computer Cams myself.
I have a 2030 in my engine, but my engine is entirely different.
Maybe a 2010 or 2020 with a 305?
I am not an expert on cams at all.
But I do know my motor worked fine with the 2030 with few changes.

Go to the Crane website and check them out.

 

thta cam looks pretty good. but you would be sacrificing the roller setr up. if you look at cranes site or call them they prolly offer a very similar roller version. most of the companies make matching models.

how much more power could a cam like that make over a 94' LT1 cam. desktop dyno says about 30 more hp, but that seems just a tad too high?

 

that may be a bti of a push. it will make more power because of the much larger exhaust side. i woudl say 15-20 at the crank would be a more legit sounding number.
the other thing i wonder is if DD takes the lower resistance of the roller lifters into account when figuring power. roller lifters supposidly can provide 20 more hp than flat tappet withthe same specs.
the roller will also idle smoother and provide a little mroe vacuum with the same specs.

I have the Crane Compucam 2030 (hydraulic roller)in my 350.
Very torquey!

hows your idle with the 2030?

 

I like it! I have it too far advanced though.... It's idling around 750.....
Nice to have that sound when you put your foot into it!
I think it is that sound we all are too familiar with!
-Snowdog

 

I would take a roller cam over a flat tappet. Just the loss of friction makes it worth it. And from what I've seen, roller cams always have gobs of low-end torque compared to a flat tappet of the same specs.

 

is your idle lopey at all

 

Nope, not much lope with 116 degree L/C.

Do NOT buy/use the 2030 crane hyd roller "compucam"!!! it has BARELY more lift than a cheapo 204/214 flat-tappet camshaft. The 2030< i believe, was a legitimate attempt at an emissions legal cam so the lift and duration was capped by the tailpipe emissions. get a Comp cam or a bigger Compucam... That cam does not use any of the advantages of a PERFORMANCE hydraulic roller camshaft. VERY MELLOW!!! Youc an use 1.6 rockers but you can also use them on a flat-tappet camshaft. IMO, go COMP! Go to the Comp catalog and check out the lift numbers. Like .480"+ on the smaller cams. NICE and what roller cams are all about.

If you have a truck or pull trailers or have a heavy car (?), the 2030 is ok, though, and does have a purpose. A ZZ4 cam would be a better choice, IMO.

 

I have a 2030 in my 350 and it is 10000000000 X better than any stock cam.
It idles fantastic....
What are you talking about Fastbroker?

 

I have a stock 89 305 TBI, is just as simple as to replace the cam with the 2030?

Although, is it possible to pass emissions with this cam???


I'm thinking about changing the cam..

 

Manuel,
Yes with the 2030 cam you should be able to pass emissions.

 

My 92 RS with 350 and 2030 hydraulic roller passes CA smog as a 305 with no trouble.
-Rich-

 

OK thanks. my concern also is that the decription of the cam said 4 or 5 speed manual. . . well, i have 700R4.


cool. so basicly just change cam,lifters, timing chain, gaskets, and new chip. that seems pretty simple. I don't mind doing the work.

although will i have that nice rumble sound with the 2030?I have a 305 TBI so maybe i should go with the 2010 or 2020??

any recommended cams for my stock engine L03?

 

I never meant that the 2030 cam was BAD, it's just not GOOD?!?!?

If you are going to come up with the $$$ to buy a NEW roller cam, get a better one, or one with at least the same duration and much more lift. Like a Comp. the 2030 is basically an anemic 204/214 SIS flat-tappet cam (.420"/.440" lift) made to roller specs... Just my .02. No flames, just my O.P. With that low .050" lift and huge lobe seperation, you are giving up quite a bit of power BUT you are making the PROM work easy or non-necessary, making idle lope/problems disappear and keeping MAP sensor vacuum high, all which could allow for little to no PROM work. hence, the emission legality and nice idle.

 

the auto woudl just need a torque convertor to be happy with the cam, prolly a 2800-3200 be enough to keep it happy.

The Crane 2030 is not good?
I disagree with you there fastbroker. It's great!
I love the cam and it was what made it possible for the computer to communicate with my motor!
Of course you must be using carb, which doesn't pertain to this particular discussion.
I guess that could be why you are saying that. Yeah you want to know what I had before? Do a search on my posts from about 8 months ago. I had a Blue Racer/Wolverine cam before. That thing was RADICAL, and did not communicate with the computer system at all. It's in the garage in a box! Want to buy it?
Maybe you should go to my page and see the motor specs I have too. It might give you a little better idea.
http://www.lvfbody.com/whoismember.asp?memberID=101
It RUNS and RUNS extremely well... and you know the sound we dream of our cars making when we put our foot in it? I have that every day! Stereo? The engine is MUSIC to my ears!
Yes the cam is just one part of it! There is more to making horsepower than the cam alone!

 

Trust me. Ask around. I am the biggest proponent of MELLOW IS BETTER when it comes to cams. It's just too mellow for me. Carb OR EFI...


As I said before, it is a great daily driver cam with a lower-end torque curve. Not bad. I am bigger into trucks than cars so I hear ya. I ran a Comp XE250 (206/212 flat tappet cam with 110 lobe sep) with TBI and it ran GREAT!!!!!!! Not too much PROM work needed (ie not much percentage changes) from the 194/214 Edelbrock 3702 cam I started with.

See my post "It's coming together" here to see what I am up to with carb/TBI and MPFI on my next engine combo.

 

I read your thread. Not EFI.

Are you going to go TBI?
Go TBI and let's see how it works!

 

read the WHOLE thread.

 

Woops. U were right. It wasn't obvious to see but the second poster understood the implied TBI testing.

I edited the main post to clear-up. Thanks.

Funny thing. the Jeep twists more now under throttle blips. Hopefully a sign of good things to come. I sene a four-link in my near future for the rear of that Jeep...

 

Rich92RS350:
Look AGAIN FastBroker!

- CRANE 2030 CAM 264/274 ADV INT/EXH
- (204/214@.050) 110 SEP .423/.446 LIFT INT/EXH

It's awesome!


I dunno where you got 116 lobe sep with the 2030!
Yes mine is a flat tappet, but then again I don't have an L03!

It's the POWERMAX CompuCam. It is Computer Friendly.
http://www.cranecams.com/master/apps/chevy5.htm
I guess there is a difference. My bad if you looked up a different cam. Yes the PowerMax is the one I did buy. Looks very similar to your CompCam.

I suppose we don't really have an argument, do we?

As for the L03 cam... someone can post the specs on it. I am sure that the 2030 has a hell of a lot more lift than that thing.
I really can't say what the 2030 will do for an L03 because my L03 blew up!

Edit: I looked it up....

Duration 179/194 @ .50 109 SEP .350/.384 int/exh

I would say it is one hell of an improvement over stock!

Even the 350 TPI had....

Duration 202/207 @ .50 114.5 SEP .413/.428 int/exh

The Police PKG had: (Again TPI)

Duration 194/202 @ .50 112 SEP .383/.404 int/exh

Anemic? Hardly.
Another thing to consider is emissions! I PASSED.

Any more lift, and that would be stretching it, I might be able to find a cam with a little more lift than the 2030, and pass, but not too much more than that. When you are talking .480 lift, you must not be thinking about passing emissions at all.

I figure (and I am sincere) that my car has around 310 HP. But it wasn't just the camshaft alone that did it! Until I get actual figures, I can't back that up. I will hit the Dyno when I can do it.

 

As far as a better cam goes, if you say to go with something hotter than the 2030, then what about max lift on TBI heads, and piston to valve clearance? Be sure to mention that, or can stock heads really take 480 lift???

 

That is a VERY good point! Be 100% sure about your heads. You don't want a cam that is going to demolish your valvetrain!
Sheesh! I see these guys talking about .500+ lift even! They must be very serious! I am somewhat serious, and I guess with the heads that I have I could go with a more radical cam, (I had one in there, just the computer freaked out with it....) but for now, I'm content.
It is somewhat milder than some of the cams I have seen on the board, but for TBI, the 2030 seems to be the nicest choice for emissions and power. It's just my opinion. I spent a lot of time looking at a lot of combinations, and all I got was more and more confused.
For a 305, it is probably about the best application. For a 350, it is a great application! There are better ones out there, and if I decide on another cam swap, I may go with a hydraulic roller cam with a little more lift than I have. For now, it is fantastic! I see no real reason to change at the moment.
And even so, IF I get anything more radical than that 2030, I would first get a higher limit torque converter, with a higher stall, definitely lower rear-end gears, beef up the suspension, etc....
Even so, with the current application I have, I nearly doubled the horsepower that the original L03 had. But then again, I have a strong 350 in there now.
Remember that the engine is only one part of the equation. You still have the transmission, and if you are going to push it, I would highly recommend getting into torque converters and tranny cooler systems.
Then the rear end....
You have to remember that the 2.73's are "granny gears" when you compare them to 3.23's or 3.42's or 3.73's.
I think I'll be okay with my combination with 3.42's. I'm going to lose a little top-end, but I don't drive my car at 145 MPH every day. It might still go that fast, but I'll be pushing up my rpms.
I want to have my rear-end gears done right the first time. I don't want to have problems with my speedometer. If and when I do my rear-end gears is just a question of getting the funds to do that. It's my next project.
I'm not saying it's wrong to get a more radical cam than the 2030, just remember the rest of the drivetrain too!

New Question:
Would a ZZ4 cam be too much for the 305 w/ the mods in my sig and a 600 cfm carb? (1.5 ratio rockers)

 

I was wondering that myself. Except I want to use the ZZ3 cam on 350 TBI heads. I have been told that it is too much.

 

I hope its not to much cam cause I ordered one a couple days ago. I have decided to go with S/R torquers with 58cc chambers if I can find some. They seem to be back ordered and World Products is in the process of moving from Michigan to New York. I guess I'll find out when I put it all togather this spring. Originally I wasn't going to go this far into a 305 but a crate motor keeps getting farther away instead of closer.I've ran up about $6000 worth of medical bills since last November.
But I need more power so cam and heads.

 

joker-
did you order the zz4 or the zz3 cam?

 

aren't they the same? Also, the World product heads should be fine, it's the stock heads with that cam that I'm concerned with.

 

The PN is 10185071. In the Jim Pace parts catalog it is listed as a cam for a 5.7L HO 350 ZZ3 engine. But it is the same cam that currently comes in the ZZ4 crate motor.

 

i may try to sell my LT1 cam and get my hands on one of those. everything will be done at the same time...cam,heads,intake,carb

 

what does everyone think of the ZZZ and ZZ2 cam (same one)?

 

I must once again bring up the fact that some people on this board have told me that the ZZ3 cam 208:221, 480/510, is too much lift for stock TBI heads. The max lift is supposed to be around 450-460. Am I incorrect??? I want the ZZ3 too, but I have to know for sure before I purchase it.

 

I know where he got the 116 seperation
http://www.cranecams.com/master/apps/chevy37.htm#6. CompuCam

 

but is it too much for L98 aluminums? i am not concerned about the valve springs as i can change those easily. i am concerned about it being too much for 305 ci

 

Concerning the L98 aluminum heads, I was looking at them till I noticed that they were angle plug heads. Then I started to wounder if they would work with my Hooker headers. On some of the plugs it looks like I would have more room. The back one on the pasenger side might be scary. I wouldn't be able to tell with out crawling underneath it.

 

according to Hedman the 68470 headers will work with GM angle plug heads only so i should be ok there. BUT is the duration and lift too much for the engine. this will be carbed. how do you think the vacuum and the idle will be? i am thinking that a ZZ4 cam on my setup would start to make power around 2600 or so+ is this correct? or would it be higher?

 

well it can't be too much for the aluminum vette heads, cause that is what cam on the ZZ3 motor with that cam from GM. Unless those vette heads had been modified by GM, then that proves it would work. But, as far as piston to vlave clearance, you may have to still use a dished piston like the ZZ3 had.
