I'm building a mild 355 for street cruising. I was thinking of the Lingenfelter 211/219 cam. I wrote Lunati and their pick for a cam was the 20080721. It's specs are 219/227 .549 .565 112 lsa 106 icl I'm running a mildly ported stock tpi intake, 22# injectors, edelbrock 60879 heads, 1.6 roller tips, and 10.7:1 compression. Any thoughts?? I think the lunati might be a bit much.
Trans is a built 700r4 with 2500 stall and 3.07 gear.

The 219 Lingenfelter cam is a hugely popular cam, I think it would work great since you had the Edelbrock heads.

An alternative option may be a zz-9 cam from TPIS or you could call and tell them what your combination is and they will suggest a cam for you that will be beneficial with the TPI intake. I have a zz409 but it isn't really a street cam. They are experts on the tpi.

If you are running a 355 with a LTR set up, I would go between 210-214 intake duration. Any more than that will give up torque, and you can't pull enough rpm with the LTR to take advantage of the added duration.

Tried their 256 voodoo cam on a TPI and was real happy with the outcome. For a small cam motor it sure made a lot of torque and didnt give up as soon as youd think it would from reading specs.

info to consider below and what do your heads flow?

That mildly ported stock intake is going to be a major restriction for getting AIR into the Eddy heads. Giving it a bit more intake duration will help with power and top-end. But, I'm not excited by the voodoo's LSA.

Consider a compromise and pick the LPE219. You get more intake duration, 10-deg less overall duration (good for TQ), and less LSA (also good for TQ).

The lobe I picked from Bullet (to make my single-patter TPI cam) would make a good choice. (If you don't see my cam specs in my sig, let me know). Basically, it's the similar to the LPE219 with a couple less degrees of duration and slightly less lift. (I'm hoping the later translates into longer valve spring life.)

There's obviously an endless amount of choices out there, but I'd just go o with an LPE219. It is a well proven cam in TPI set-ups.

Go with the 219 and buy a new Lingenfelter base.

If you're talking JUST the base -- if someone can only afford the base OR the runners, I'd vote for runners. Typically, you want the intake tract to narrow/tighten to speed air entry. Having bigger tubes creates more of a funnel effect than stock tubes with larger base.

Having some semi-siamesed SLP runners would be my first vote....for a cheap, stock-like alteration to the OEM L98 setup. One rule of thumb that might be good for the OP to know is: Your intake should be capable of flowing up to 15% more than your heads. In your case, it will be the reverse.

With those Eddy heads, an intake that focuses on low-mid power would be great. FIRST, SuperRam, or large-TPI TPI. And, it takes a very good longtube setup to hit 15% over those Edelbrock heads.

I'm guessing your mildly ported tubes will be somewhat of a disappointment.

Thanks everyone. I'm surprised I haven't heard much about the lpe 211/219 cam. With my small intake manifold I thought that might actually be the best. I was looking into a superram but can't swing it right now due to the trans upgrades. People are actually having good results with the 219/219 lingenfelter on a tpi?? Maybe I'll look into that.

Give it a try, you can always add the intake later, many people the caught up in the "perfect" combo, and it becomes a run away train.

Try it, gauge the result and then do what you can when you have the cash

dont want to ruffle feathers but the 211, 213 256 260 262 219 pick one and put it in. Do intake later as said.....one thing at a time as you can afford it.
Dont think there is any perfect combo outside of on paper.
BTDT gave up. Put a cam in it and run the b1tch.

I used the ZZ409 cam. It is great. I also had a 355 TPI built with 1.6r. TPIS did the custom chip work and dyno tune. 8 hr drive (and 2 tickets) to their shop, but worth it. Very sharp guys with the TPI stuff.
Engine pulled 325hp and 365tq at rear wheels (if I remember correctly). I can send a pick of the dyno sheet when I find it.
However, here is a link to a video of my idle with everything done and after tune. Also I added dyno run from the TPIS shop.

Same here, no ill will intended,

C4KC, very nice idle, my new 224/234 should sound similar

MDstar2

Sounds good C4KC! It's all good guys. I can take it. LOL. Thanks for all of the input.

I used the GM HT383 cam, the same one that is in the ram jet 350 crate engine, and also known as the "marine cam".
You can't believe the torqe that thing puts out, and in addition, I get superb gas mileage, (which in these time, is a plus), and a dead flat smooth idle.

I know what you must be thinking, but it works for me since the TPI doesn't rev very high.

I ordered the Lingenfelter 74211. We will see how it runs with my less than stellar performance package. I think it will suit what I'm building for just fine though. Thanks again for all of the input. It was greatly appreciated.

Hey all. It's been a while getting everything done on this project, but I'm finally there. I ended up with a 10.4:1 355 with a lightly ported stock tpi intake with stock runners. It has Edelbrock Performer Corvette heads with Comp double springs and 1.6 pro magnum roller rockers. I installed the Lingenfelter 211/219 cam, straight up. It also has TPIS headers with no air or egr. Pcm of NC did a mail order tune on it. I installed a road race ready 700r4 with 2400 stall and it has stock 3.07 rear.

Here's how it sounds: http://youtu.be/gIW7tePIXGg

The only time I had it to the track I ran in mine shaft air and it ran

1.794 60 foot
5.316 330 ft
8.260 660 ft
10.810 1000 ft
12.950 1/4 @ 109.42

I'm quite pleased considering that was the motors break in and it's had zero tuning.
