I know this cam is not ideal for the LS3 head but I have a Trickflow 216 220 114 .560 sitting here brand new which we use for 5.3s but Im thinking of trying this cam out on a 6.2 in a truck

Anyone ever run one of these cams with LS3 heads and live to tell the tale? Because I'd like to hear about if you have

I say try it.

You WILL gain power with it, but there are smaller more effective cams that will equal or better it.

I might, certainly thinking about it

Not sitting on my shelf there isn't

The LS9 cam is an option that is hard to look past though

G Atsma

If you plan on supercharging, the LS9 will do a great job.
NA, not so much.
Then the cam you have will do a better job.

The LS9 cam will make more peak power, its tried, tested, and literally mind blowing what numbers it puts down on 6.2L engines. LS7 cam is basically the same cam with tighter lobe sep. Neither cam shines in that dept so down low they both might suffer against the 216/220 which should be very snappy. One of our members picked up 43whp with an LS9 cam swap in a 6.2 truck. Thats nothing to sneeze at for $110 bucks

I'm mostly curious if anyone did the baby 216/220 and had real world driving feedback to offer. There must be someone out there, I found this today

I think your cam will be more satisfying to drive than the LS9, with power all up and down the curve. The LS9 DOES give a good top end, but the bottom end IS weaker. Since you have the cam in question, I would use it!

I most likely will. I changed up a lot of plans this year, shook off stalled projects, cleaned up a bit and have gone back to some HotRod roots of "use what I have" plus I am curious for my own sake how this little cam will perform on the rect port heads. Still interested to hear comments or experience from anyone else as well

G Atsma

You know, it's kinda cool to look at lists of cams and think "Well this one will give me more high end while keeping the low end", or "this one will REALLY grunt on the bottom, and still rev to the sky". And they ALL will require expenditure when you now possess a good cam. Even the LS9 will cost about $100. A REAL DEAL, but still $100. Use what you have and you will have a good time with your ride!

I had that 216/220 cam briefly in my G8. It made more power and torque than the stock DOD cam, but didn't offer the stock-like manners and driveability I was after. I put an LS7 cam in it's place and noticed a small loss of torque just off idle but that seemed to disappear by 3000RPM and the car was much faster overall (more midrange, LOTS more top end, and no traction problems), idles at 600RPM, and drives perfect. Never had either on a dyno, but the LS7 cam pulls clean to 6800RPM where the 216/220 cam felt like it was done by 6000RPM.

The LS7 is this: 211/230 .560/.557 120+4 Correct? and the 216/220 114+4 was less effective?

I thought those rectangular port heads needed different caming technique than a cathedral which is what the 216/220 is designed for.

Hmm thanks Marc, thats interesting. Was it the trickflow 216/220 114? I was thinking it would carry a little higher to maybe 6500but maybe not. What intake/exhaust system were you running with the 216/220? How was the idle? Did you have it tuned?

Felix ideally the rectangle port heads do need a lot more split due to the big intake/exh flow bias. I run a 222/230 in my camaro that is great, just a tad too choppy at idle for my goals or id run it. LS7 cam is the same as LS9 is it not? IIRC its only the lobe sep thats different by a few degrees. Both those cams run a wide split to eliminate any overlap/reversion issues which helps them run cleaner. Overlap is tricky with these heads but the 216/220 is on a 114 so there is not much.

Yes, TFS cam. I have the same cam in my Camaro with a 5.3L.

G8 intake/exhaust is CAI with card MAF, stock intake manifold, and 1 7/8" Kooks LTs and midpipe, no cats, Hooker mufflers. Professionally tuned, and retuned. 700RPM idle in gear gave perfect throttle transitions but pushed through the brakes (stock converter). 625RPM didn't push but was intermittently unstable coming to stop during 2-1 downshift and off idle. That along with a power peak just barely above the stock RPM made me pull it out.

LS7 and LS9 cams are quite similar. Valve events are a couple degrees different, base circle is smaller on the LS7 and the ramps are designed for a 1.8 rocker. You can use a 1.7 without problem of course along with GMPP drop in springs.

Your doing a fine job of talking me out of this experiment lol! Thanks for the detailed info, I do appreciate it.

Probably end up using a 210/224 by the time this thing is built. We'll see
