Edelbrock 2215 and 2216 cam Found some info I did not see before:
DESCRIPTION: The Performer RPM Hydraulic Roller Camshafts for Chevrolet LS1 engines are designed for optimum power and torque in the 1500- 6500 rpm range. #2215 provides 12” of vacuum at 1000 rpm and #2216 is slightly more aggressive, providing 10” of vacuum at 1000 rpm. These camshafts are ideal for performance vehicles with LS1 engine swaps, using Edelbrock’s Performer RPM LS1 Carbureted Intake Manifold #7118 and a carburetor. In our testing, a stock LS1 engine, using our Performer RPM LS1 intake manifold made 420 horsepower with camshaft #2215, and 460hp with #2216. Stock lifters, pushrods, and valve springs may be used with either camshaft. However, stock valve springs should be checked for potential coil bind at the lift specified for the camshaft being used. Upgraded valve springs MUST be used if coil bind may occur. NOTE: These camshafts are designed for LS1 engines being used for engine swaps into earlier vehicles using a carburetor ONLY. They are NOT intended for use in factory EFI- equipped LS1 engines.
So, makes me wonder how hard I can make the 4.8 in my RS run next year. Let's say my 295 ci motor is down 50 ci, and translate that to 70 less HP from the 2215 results. 350 hp from the 4.8. Then add in my ported heads, and that gives me 30 hp back. 380 hp from a 4.8 is not bad. But the 2216 in the same difference would b 390ish(that is hard for me to think but you neve know), then call it 420 with port work, that sounds better, but how much more radical will it be and how far up will it move my much needed torque with the little 4.8? So, I will juggle the two grinds around in my mind till I pull the trigger at the last minute.
Nitto mention I will have to spin the little engine harder, so it makes me want to use the 2215 with the older 4.8 and try the 2216 with the 2009 4.8 when I get it into a S10.

i looked into using one of these also. i thought the smaller one might be too small for what i wanted. i was leaning toward the bigger one until a buddy mine put it into a compression calculator and even with milling the heads .040 (which is max from what i could find) and using a .041 head gasket the dynamic compression was still low.

[QUOTE=Pop N Wood;16948308]A stock, carb'd LS2 crate motor is rated at 440 HP. They come with 243 heads and essentially an LS6 cam. Why those cams over an LS6 cam?[/QUOTE
what's spec on cam?

A LS6 is not carb specific and will absolutely promote no torque, although it will pull into the RPM half decent. I am looking for some low end the 4.8 does not have and the desired sound, the lope that all third gens should have.

Yes and no. With these cams, a cheap set of 60$ LS6 springs are more than enough. At 300$ for the 2215 and 330$ forthe 2216, the savings start right there. Not to mention off shelf cam grinds at are tried and true from edelbrock from the results I found above. If max power is a need, or want, then expense is not spared and these cams should be avoided.

I keep comparing that smaller one to the LS2 cam I already have. It doesn't look like much of an improvement. The 2215 has a fair bit more duration, slightly less lift and a a tighter lobe separation than a LS2/LS6 cam. But the advertised 430 HP / 420 ft-lb torque is less than the LS2 crate motor's 440/415.
Edlebrock's numbers are for CNC heads on an LS1 with a dual plane intake.
Maybe the numbers are less due to the displacement difference and using a dual plane vs. single? Probably need a full dyno curve to be sure.
At any rate probably not worth the money for someone starting with a motor that already has an LS2/6 type cam

Says stock ls1 in what I posted above. So 346 cubes and heads flowing mid 220s sounds like there is more potential with good heads. But if they were CNC heads, I wonder who's they were? Anyway, the sound of the 2215 and throttle response down low would be worth it over a stock idle ls6 or 2 cam for me all day.
