Cam Choice Guide And Question Post


Recommended Posts

I just bought a new cam and was wondering how it will act with my mods? Specs 218/228.563" 116LSA+2 advance. I also got some TEA .660 dual springs and 7.400 pushrods. My stock trans finally gave up after 100k miles 70k blower miles. I ordered a new trans from Performabuilt level 2 with a 2800 billet torque converter. I am going to pulley down to a 2.8 and am contemplating meth because I live in the valley where its always hot just about .

I did the cam reccomendation through comp cams and they came back with 269Lr HR12 http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=1400&sb=0

 

Just thought I would get some other opinions before I drop the money and work on it.

Cam list:

 

Comp Cams:

XR259HR...206/212 .515/.522 112LSA. Great cam for a stock truck looking to make big low rpm torque and use a stock torque converter. Better suited to a 4.8L or very mild 5.3L. Recomended torque converter would be no more than a 3000 for a 4.8L or 5.3L and stock or 2600 for a 6.0L. Recomended valve springs would be LS6 GM springs.

 

XR265HR...212/218 .522/.529 114LSA. Great cam for a stock truck using stock truck exhaust manifolds and either a stock converter or low rpm stall. In a 4.8L or 5.3L I'd recomend a 2600 to 3000 stall. In a 6.0L I'd recomend a stock or 2600 stall, but the 2600 would be better suited to the job. Recomended valve springs would be GM LS6 springs.

 

XR269HR...216/220 .525/.532 114LSA Decent cam for a bolt on type truck running shorty headers or long tubes. Stock manifolds could be used, but headers would be a bigger gain at this point. For a 4.8L this is a fairly agressive cam and I'd recomend at least a 2800 to 3200 stall. For a 5.3L and 6.0L a 2600 to 3000 stall would do the job nicely. This cam isn't really recomended for gains with it's low lift and bigger duration. Other than great valve spring life there isn't much reason to run it. Recomended valve springs would be LS6 springs.

 

XR273HR...220/224 .530/.534 112LSA Decent cam for an LQ9 for someone worried about valve spring life. With this much duration and this low of lift I just wouldn't recomend it as a choice for any application.

 

XR277HR...224/228 .534/.537 112LSA Agressive cam for duration and LSA. Not enough lift to make it worth recomending at this duration.

 

XR265HR...212/218 .558/.563 115LSA Very nice cam for a truck with mild exhaust upgrades. Not a recomended cam for a 4.8L or 5.3L as this much split with the small intake valves isn't the way to go. For a 6.0L this cam makes for a nice and mild dail driver with very little lope at idle. Stock converter can be used, but a 2600 stall is recomended. This cam can also be used with a blower or nitrous with decent results. Recomended valve springs would be LS6 spring or Comp 918.

 

XR275HR...222/224 .566/.568 112LSA Very strong cam for a naturally asperated setup. In a 4.8L you'll need a 3000 to 3400 stall. In a 5.3L you'll need a 2600 minimum and best results at 3000 stall. With a 6.0L I'd recomend a 2600 to 3000 stall depending on how agressive you want the launch. This is a very good cam for torque in the middle rpm range. Recomended to use shorty headers or long tubes. You may also need an injector upgrade at this point. With good tuning the idle will be a bit choppy, but yet still very streetable and will make for a nice daily driver with some bite. Not recomended for nitrous or Supercharger. Recomended springs are LS6 springs or 918's.

 

XR281HR...228/230 .571/.573 112LSA Very strong cam for a naturally asperated setup. Not recomended for a 4.8L or 5.3L. An L33 5.3L H.O. could run this cam with it's increased compression, but would require a 3200 to 3600 stall to be happy with it's results. In a 6.0L I would only recomend this for an LQ9 with it's increased compression and it could be ran with less stall due to it's cubes and compression. In an LQ9 I'd recomend long tube headers, LS6 or Fast style intake, and larger injectors. I'd recomend a 2800 to 3400 stall behind an LQ9 with this cam. Idle even tuned in perfectly will be choppy and will make for a decent daily driver as long as you aren't in heavy traffic. Not recomended for supercharger or nitrous. Recomended springs would be 918's.

 

XER273HR...224/230 .581/.591 114LSA Very similar power band to the XR281HR, except with a better idle and better drivability. I would not recomend this for anything smaller than a 6.0L either. Recomended to run a shorty or long tube header. Larger injectors will be needed. I'd recomend a 2600 to 3000 stall for this cam. If it is well tuned in the idle is lopey, but not unacceptable for a daily driver. This cam will also work ok with L92 style cylinder heads. It happens to be one of the cams that Livernois has chosen for it's L92 package. Will work nicely with nitrous or a blower. MP122 or bigger for Magnacharger or D1SC for Procharger. Recomended springs would be 918's or 921's.

 

 

XER281HR...232/234 .595/.598 112LSA Pretty much a cam built for no smaller than a 6.0L. If you want to run a cam like this you'll want more than the stock compression of an LQ9. I'd say no less than 10.5:1 compression. You'll also want a car intake for this rpm range. With a 6.0L you'll want a 3200 stall or higher. This cam is better suited to bigger inch such as 6.7L and bigger. Not recomended for boost or juice. Recomended springs would be 921's or Partriot Dual Gold's.

 

XER287HR...238/240 .605/.609 112LSA If you want to run this with a 6.0L, shoot for 11:1 compression or higher, a stall of 3600 or higher, 1 7/8 headers, and a Fast intake. This would make for a nice agressive cam in a 6.7L or bigger that can still be daily driven. More cubes of course wouldn't require as much stall. Recomended springs would be Patriot Dual Golds.

1quicktruck here. Just wondering about a cam for my truck. 373 gears .Tires 285/60/18 . No cats shorties ,magna flow exhaust, 5.3 liter. 160 stat. Corvette servo and shift kit . magna charger with stock pulley. Fast chips custom tune w/dyno. No stall converter. I like a nice lope but I dont pull anything other than a garden tractor on a very small trailer. in the summer only. It has 87k miles now but I dont race other than mustangs every once in a while or whatever.. Mostly a dd. I think u suggested a LEP Stage 1 224/230 and something about 116? No hurry take ur time. 2004 silverado extended cab.
