Anyone here had lingenfelter perform the basic 350 package to their car? What do you think? Worth the money?

Thanks,
Scott

 

See sig for mods. I have had the package for over a year now. The car runs perfectly and no complaints on workmanship, but I would not do it again. The feel of the car is simply not different enough to justify the cost. If I had it to do over again, I would either go with the Magnuson s/c (which I may still do)or save my pennies and go for a 427.

 

See my sig for details re mine. I love it. Just coming up on 4,000 miles; of course, it's still wearing in; was great to start, and is becoming noticeably even smoother as the miles go by; probably making 400 rwhp at this point. It is MUCH stronger than the stock '01 Z51/MN6 Coupe I traded in for it; easily breaks stock EMTs loose in 1st and 2d as rpms climb past 4,000. (FWIW, I was told at the time of delivery [start of this year] that mine was the strongest LS1/6 heads&cam they'd ever done, by the better part of 10 rwhp.)

Absolutely no issues so far. Idle is almost dead still at this point, which actually they did not think would be the case (mine was the first with a new cam that I've been told they're using generally in their packages now -- at the most, just a slight lope, no misfires or check engine lights -- idles solidly at just under 900 rpm, has never even hinted at a problem with falling idle rpms, such as when the A/C comes on or whatever). Highway MPG has run 1+ MPG ahead of my experience with the stock '01 during its first 4,000 miles.

In my opinion, absolutely worth the money! I know there are plenty of folks out there with stronger cars -- I intend to address that with my next project for LPE(!) -- but my LPE heads&cam IS one sweet and strong C5.

Hope this helps.

 

I just got back form LPE, installed a set of 1 7/8 headers, hurst, and Corsa T1,
did some dyno tuning, got a little bit higher peak numbers 25 rwhp 6 rwtq, but power under the curve there was a large gain as much as 45 rwtq and 34 rwhp and it carries those gains for a while totally different car, oh yah it is a 383. Also at LPE there was Joe Cool having his super charger installed at the same time, it looked great, idled like a rock, if i would do a change or consider a head and cam there would be no dought i would install the super charger, for the money you can not touch this, it will pass the smog test, will make anywhere form 430 - 450 rwhp and tq in same range, you could not tell there was a blower in that Z, the only thing that would give it away is the hood which actually i did not notice untill i got behind the car and saw the higher cowl.

I as was Joe Cool were totally impressed with the proffesional, perfection is the rule, work and pride this group at LPE have, they would detect any miss alignment and fix it, make a new bracket, trim cut it what ever it takes, things that others would leave, they find and fix. When i first talked with Tim at LPE he assured me that the car will be perfect, well they do not, will not rest until it is, every worker there has a role, you can say this is a all star motorsports team, i spent two days there and as you can tell i was verry happy. I almost forgot it does not leave untill John Lingenfelter test drives and give's the ok.

Verry happy and thanks to LPE,

:cheers: :cheers: :chevy :chevy

Tornado-

Your numbers are very impressive!...400rwhp without headers is a very strong car indeed.

Did you end up buying the LS6 Heads from Lingenfelter or did you supply them yourself from another vendor?

Thanks In advance

ledfoot --

actually, re headers, ummm . . .

I got the LS6 heads thru LPE -- I may have been able to save a couple hundred by getting them somewhere else; but I'm one who doesn't mind LPE making some money working on my car, considering the confidence I know I can have in their work (which is NOT in any way to slam any of the other great tuners out there!)

Hey Tornado ... what is this "next" project for LPE you are talking about? TT? SC?

 

Tim at LPE showed me a red Z yesterday w/ SC when I dropped my C5 off for some work. I think it's the same car your talking about. Very nice car. You have to give LPE credit they run a hell of an operation. I really feel good about having my car there. Can't wait to get it back!!!!!

 

Well, mine is the 650+ package.

I highly recommend LPE. :yesnod: :yesnod: :yesnod:

If you live reasonably close by, you don't even have to think twice.

NewVetteLover --

Too early to tell exactly (I'm not quite ready to start this just yet), and actually don't even know if LPE will be doing such a combo down the line, but I'm thinking C5-R block and C5-R heads TT . . . it is my understanding that the centers of the valves in the LS1/6 heads are only so far apart, so that at some point to make one valve bigger, you have to make the other valve smaller, thus placing a limit on just how much valves you can use with those heads, and thus limiting just how much those heads can flow, whatever you do -- and it is my understanding that the C5-R heads solve that issue, and can flow much more than CNC'd LS1/6 heads . . . thus a 427TT using the C5-R heads should be able to make the same power as a 427TT with CNC'd LS1/6 heads using a good deal less boost -- or with the same boost should be able to make a good deal more power . . . :eek: :eek: :eek: :eek: :eek:

 

Yes, the C5R heads flow better.

LPE already have experiences with the C5R heads + C5R block 427 TT. It made a bunch more power over using the LS6 heads. :yesnod:

That's why I am running higher boost... I want that engine. :D

 

SlowC5 --

Can you say any more re the 427TT using the C5-R heads??

Like anything at all re how much power, on what fuel, at what boost??

I can't help thinking that that engine, in a fully street/emissions-legal 6M C5, running boost not requiring more than basic pump 93, could make at least close to 1000 bhp/850rwhp (if not more), and (with slicks and a good driver under decent conditions) could consistently run (well[?]) into the 8s. Am I nuts??

I mean, from NORM KOERNER's signature: "2000 Z-28 LPE 427 C5R BLOCK AND HEADS.....9.51@148 MPH SO FAR......" -- I understand that that run was indeed all engine, no boost, no nitrous -- !!! :eek: :eek: :eek: :eek:
