Edelbrock offers 2 carb'd LS cams mathed to their intake packages, I was thinking of picking up the 2216, anyone try one already?

I am looking for low end/ mid range and to keep my stock valvetrain which this seems like it would be easy on. Mainly due to the low lift, but I could upgrade to higher ratio rockers if I wanted to step it up in the future. Not to mention with my Edelbrock discount its only about $275

 

Good post. Ive been thinking about which cam to run when I get my engine ready for my 67 Camaro if I go the LS route. The 2216 looks better as far as duration goes. Have you done any research on hp numbers with people using the MS3 cam in carbed' setups? I know that cam sounds even more wicked on a carbed' engine. Sounds like your just trying to keep it simple and matched though...smart move.

 

The second grind i like for a fun street ride, but the first would work well on a mild engine combo that would still be fun to drive.

 

The MS3 is fairly popular on here it seems. I have to admit it does sound pretty good. The main reason I am steering away from many of the popular cams on the forum is because after doing research the peak numbers are awesome, but I am really looking to boost my low and midrange. Same reason I went with the dual plane carbed intake, I forgot who did the dyno test, but with the dual I lose about 12 ftlbs on the top end, but gain 44ftlbs on the low/mid range over the single plane.

 

Found it!

Super Chevy Intake Test

 

That 220 grind would work bad *** with the dual plain, big torque numbers.

 

What makes them carburator only cams?

The 220 cam looks a lot like the LS hot cam, but with matched intake/exhaust durations.

The second cam looks just like the LS Stage 2 cam

 

I really considered the 2215 for my build. However I decided on the Comp XR275 because it had more lift. Another thing to note about the Edelbrock cam is the intake centerline. The 2215 has an intake centerline of 108 degrees compared to many cams of that size that have an intake centerline of 110. This will move the powerband lower and limit the rpm a little.

The 2216 has an intake centerline of 106 degrees which is reminiscent of the old small block Chevy circle track cams. This will also move the powerband down.

Most of the LS cams tend to have less advance than the old SBC style Edelbrock cams. I am quite curious to see how they would perform comparative to the Comp cams of similar duration.

 

Speedtigger I think you are meaning lobe displacement angle. Intake centerline is about how a cam is degreed in when installed in a motor. Lobe displacement is fixed, the smaller the # the more overlap. Edelbrock cams are kinda ok . There are much better out there. Edelbrock says "carb only" because you need a tune for then to run with fuel injection. From reading your previous posts I know you understand this.

Actually I am talking about the intake lobe centerline. The Edelbrock cams are more "advanced" in their timing than most typical LS camshafts. I am not sure if this is purposely done after testing, or if they just applied an old school SBC type grind to the LS camshaft.

 

Does make you wonder, i would hope they had R&D on a LS base engine to see how it will work. Older SBC cams just wouldnt be the same in a LS.

 

Be nice if HotRod or Car craft did a comparison between F.I.cams vs Carb'd cams using the same intakes? I had Futral Grind my cam cause at the time no one offered a off the shelf cam for carb'd LS's

 

My buddy put the 2216 in his 6.0L and I believe he likes it a lot and is real happy with it. He said he saw an article where they made 480HP(not sure if at the crank or the wheels) with that cam. It sounds good, but he hasn't run it at the track or anything. It's more of a cruiser type truck and it gets driven long distances.

 

This winter I am swapping 243 heads (Z06) and the 2216 cam into my LQ4. As mentioned above I am running the dual plane. I plan on getting it tuned and dyno'd this spring and will definetly post the graphs from that.

 

I like the 2216 cam. But honestly I would get a nice custom cam cut for your desires. Not much more at $400.

 

My only complaint is the lack of lift, the Vic Jr intakes flow nasty high numbers up top that the EFI cannot, so not going to .600 lift is holding back on the 2216.

 

I agree, for the time being that low lift is great for my stock LS6 valvetrain, but if I want more power (who doesnt) a future upgrade could be some 1.8 rockers, new springs and pushrods.

 

makes more sense to me to pay for a matched to your combo custom cam. i would take the LPE GT11 over any of those cams.

 

Phew. That bad boy has some lift

high lift lowerish duration will make TONS of torque
