Is the B303 a cam that would be good for a truck? I was looking through Summit, and this is what I think I have narrowed it down to depending on how the B303 is.

Crane Truck cam:
Specifications:
* Advertised duration: 260 intake/272 exhaust
* Duration at .050 in.: 204 intake/216 exhaust
* Gross valve lift: .456 in. intake/.484 in. exhaust
* Lobe separation: 112 degrees
* RPM range: 1,500-4,500 rpm

Crane 2030:
Specifications:
* Advertised duration: 270 intake/278 exhaust
* Duration at .050 in.: 216 intake/220 exhaust
* Gross valve lift: .533 in. intake/.544 in. exhaust
* Lobe separation: 112 degrees
* RPM range: 2,000 to 5,500
* Delivers great mid-range torque and horsepower.

Crane 2040/ E303:
Specifications:
* Advertised duration: 282 intake/282 exhaust
* Duration at .050 in. cam lift: 220 intake/220 exhaust
* Gross valve lift: .498 in. intake/.498 in. exhaust
* Lobe separation: 110 degrees
* Basic rpm range: 2,400 to 6,000
* Good mid-range and strong top-end power, requires mass air flow fuel injection, aftermarket intake, heads, exhaust for best results, best with five-speed trans with 3.55 or numerically higher rear axle gears

I just want whatever cam will net me faster 1/4 mile times, I was thinking the 2030 looks like the best, because it looks like it has a good powerband

 

the e-303 has a lot of duratioin so it will be good for the drag strip (assuming you will be seeing those rpm's while racing), but it will probably be a not-so-good street cam on a heavy truck. the 2030 looks nice, just make sure you wont have any piston-to-valve clearance issues because .533/.544 is a whole lot of lift (which might also cause your mpg to take a decent hit). are these cams hydraulic roller? have you considered going with a custom made one? most of the time, they are really worth the money since theyre made to work with your exact setup. just some info, good luck man!

 

B303:
Specifications:
* Advertised duration: 284 intake/284 exhaust
* Duration at .050 in. cam lift: 224 intake/224 exhaust
* Gross valve lift: .480 in. intake/.480 in. exhaust
* Lobe separation: 112°, retarded 5°

This probably has too much duration for a truck, and the built-in 5° retard will kill the low rev performance.

The 2030 cam needs improved heads, 1.7 roller rockers, intake and exhaust to really do it's thing. The "right" cam is really dependent on the rest of the engine and on the weight and use of the vehicle. You need to make some decisions about what heads, intake manifold and T/B and exhaust you're ultimately going to run. Talk to the techs at Crane, they won't steer you wrong.

 

I guess I will call them. I want to do all the good engine stuff, but that will have to wait a while, until I have a steady income. So I guess I will just see what Crane thinks I should use for my truck. The only other things I think I will do will be headers, electric fans, and maybe the Edelbrock TB / upper/lower intake, until I can start doing all that other stuff. So I will see what they think I should use for that.

 

Those guys will give you a recommendation, but it wont be anything they know about personally...they basically look on there computer and push buttons to tell you what you need. Not that they would ever recommend a bad cam, but they arn't real great at answering technical questions about the cam. Comp has a little better staff on hand and they actually go through your setup and work with you to get a cam to match your driving style. Whatever you do, Stay clear of those motorsports cams!! They are about as generic as they come. They can produce nice power, but there is alway something they sacrifice that another cam from a diff manufacturer can do better on and still get the same power. The B or E cams both have problematic idles. Some HP junky mustang guys even trade out there E cams cuz of the idle problems (even with the mass air). Over on the Corral they are talking about raising the idle speed to make it a little better. I would say the biggest you wana go for a street worrier is that 2030. If you can afford it, a custom grind is the way to go, however if your like me, every dollar extra means something else that you wanted to do to your truck now is put on hold. Im going with the 2020 (208in/216ex), but of course I am running speed density 351 and not nearly as conserned with 1/4 times as you are. Im in it for the big block torque feel, whether 5000rpm horsepower is there or not I really don't care.
Call Crane, then call Comp and they will give you a realistic feel for what sized cam will make your truck perform the best with your stock heads/intake.

Just curious, you planning on installing this thing yourself?

Best of luck

 

Yes I would install it myself.

 

Beastie,

How are the smog laws where you live? Is this something you have to worry about or do the words "emissions legal" never enter your vocabulary? Here in California, I'm pretty restricted as far as which cams I can put in my truck. You're pretty lucky if this is not a concern of yours.

I was just thinking though, you're going to have to make some sacrifices somewhere. Since your truck is your daily driver, I'm sure gas mileage, idle quality, and low-mid range power must be concerns of yours. But since you also want something that'll still give you high end power for the drag strip, it's like a best of both worlds scenario. If I were you, I would investigate how much a custom ground cam would cost as that seems like the best solution for your needs IMO. I think that might be a route I go when my engine eventually runs its course. But once again, I still can't believe you're thinking about cam swaps when you don't have headers yet. Those should really help everywhere, especially @ high rpm's!
