better the heads requires less of a cam right better the heads flow requires less of a cam right.
? on a 346CID whats the mildest cam that will flow 100% on a set of AFR 205 heads?
I don't want to install heads then find out my current cam is only good for stock 853 heads and I never see the absolute potenshale preformance from a head upgade.
Thanks

heads & cam nice cam specs. sounds like it's not to mild and not to wild best of both worlds.
hows the power under the curve? what RPMs do'es the powerband start & carry to?
Thanks

more CID 
Check on Vinci's web site, the cam you are running was mated to a set of AFR's (un-milled and stock gasket as I remember), which should give you an idea of what to expect.
I have the same cam you are now running. I also have a set of AFR's on my workbench that will go in this October along with the AFR 6016 cam (224/228 114 LSA). Note also that even though the cam specs at 0.050 are smaller on your current cam (216/224), the seat timing is actually more due to the slower lobe design.

Afr Vinncis is where I purchased my cam (Joe & Roger are very knowlegdable on LSX stuff) I haven't looked at there website for a few years I'm now thinking the shark project car has these AFR heads?
Why are you slitely upgrading you're cam ? to make sure you'll get all the potenshale from the AFRs?
How are you liking the 216/224/551/551/115? I think the torque is awesome even compared to more aggresive cams.
I am also considering a slite cam upgrade before the AFRs 205 https://www.patriot-performance.com/...age=1&featured

The project that did the heads was a C5 Corvette. The heads were first installed, then the cam later.
I was looking for a bit more power from the car without sacrificing drivabiltiy at all and the AFR cam that I selected meets those requirements. At first I was going to leave the cam alone, but decided to try and take the car to the next level. You are correct though, the car right now does have very good street manners and good low end power. I bought the cam from Joe at Corvettes at Carlisle a few years ago and have been very happy with it even though it is considered too small for many on this forum.
If you are going with heads, the AFRs are a nice head and should perform well for you. I would bump compression a bit by milling them. Contact Tony Mamo directly for advice, he can best provide input on how to set up the heads.

H/c Jon[/QUOTE]I've been holding off on my heads cam upgrade untill I upgrade the fuel pump & injectors which maybe coming soon.
looks like the AFR205s and the 224/228 .581 .588@114 https://www.patriot-performance.com/...age=1&featured
will be my choice.
just curious about the 114LSA and the auto. trans. I like the sound of a 114 compared to the 115 I had the understanding that my 115 cam was designed for auto. trans.
Interesting concept. Why did you say that?
Jon I said that to get feedback.
looking for replys like
1.drivabilty
2.stealthness
3.more low end power
4.being able to add more timing campared to a bigger cam.
but most of all not getting all the use out of a set of expensive heads.
Thanks

The head determines the height of the entire torque curve and the cam determines how the torque curve "rotates" about the max torque rpm point.
So you can have good low end torque as well as high end power with a great head and a fairly tame cam. You don't get that from a poor head and cam no matter what the cam. We've all seen high hp at 6500 rpm combinations be down 30-50 lb-ft at 3000 rpm because a long duration cam needed to be used to get the hp number.
A fat, flat trorque curve, like 350 to 400 lb-ft (rw) from 3000 to 6500 makes a very driveable car and still makes about 450 rwhp @ 63-6400 on an A4 346 engine. That fulfills your 1. thru 3. above. Not sure why you want 4.
One way to look at a combination is to compare minimum torque to maximum torque throughout the rpm range you plan to run. in the 350-400 example noted there is 87% of MAX torque available from 3000-6500 and 80% of max torque available from 2500 to 6600.
I like to look at the rpm band for 80% of max torque to get an idea of driveability, especially the lowest rpm where 80% of max torque occurs. 2500 rpm is nice.
Done correctly with excellent heads and matching cam, a 510 rwhp 402 can have 80% of max torque @ ~2000 rpm That's driveability, stealth and low end.

learning this is what I'm all about power under the curve I'll let the big cam folks drive around at 6500RPM to get there power meanwhile I'll have power I can actually use.
#4. from what I understand the smaller the cam the more timing can be added.

Thanks for the explaination.

The cam I am running now if from Vinci website it is their XXX cam. I am goin to put AFR 205 heads on in a couple of weeks using there handheld tuner. I am expecting nice results.
