Considering LPE 427 C6
I am relatively new to the forum and have just posted a time or two, but love the C6 and strongly considering one. Would love a convertible Z06 but that obviously isn't in the offing, considered some aftermarket conversions (de-roofing) but the comments by some here about the inevitable weakening of the aluminum frame has dissuaded me from that approach. I then remembered some of the posts here about tuners and have spoken to Tim at LPE (Lingenfelter) about dropping a C5R based 427 into a stock convertible, possible also widening the wheel well to accomodate sticky tires. The cost of this wouldn't be much more than the price that Z06's are going at with the dealer mark-ups.
My question is one of naivety but is essentially this: would you guys be afraid to do something so drastic to a new C6 convertible. I've heard good things about LPE and imagine they would do as good a job as anyone in the industry, understand as well there's a 2 yr/24,000 mi warranty of the drive-train. I just wonder whether doing this would invite a lot of other problems, i.e., if the 427 motor would give me as good a service as leaving it stock or create a bunch of other issues that I would have to get worked on. I can't honestly claim to be much of a mechanic myself, live about an hour from Nashville, don't want to get stuck with something that requires a lot of maintenance and work. But I've got to tell you, I am enthralled with the idea of that engine in a C6 convertible and think it would be tremendous fun.
As an aside, I've actually considered the twin turbo option as well but frankly not sure I would be safe driving it. Bunch of the reviews of TT packages in LPE vehicles (linked to their web-site) described them in glowing terms but almost unfailingly described that it created so much wheel-spin that the incremental benefit of the extra torque was a bit ambiguous. I guess this could eventually be overcome if you got tires big enough although I'd still be afraid the back end would fly out from under me.
Anyway, I'd certainly appreciate the thoughts or advice of anyone who has been down this road before or considered these purchase options. I'd like any info about the longevity of those engines (used mostly as a daily driver). Again the sales guy at LPE was very helpful but I've come to respect the objectivity of the posters here on the forum.
Hope this isn't a dumb question, I've just never had any experience with "crate" engines before. I thank everyone in advance for your patience and replies.

But them ugly wheels gotta go.
Another good thing about the Lingenfelter package is the 24k warranty
I think they quote about 530 hsp for the 427, say it should be a little faster than the Z06 although there would clearly be some difference in weight. They quote about 500 hsp for a 403 cc engine which they also offer.

That being said i looked into a TT C5 from LPE. If i was going to do that kind of a modification LPE would def. be at the top of my list just for piece of mind that my car and myself would be taken care of.

The Best of Corvette for Corvette Enthusiasts
Some will try to pursuade you to go elsewhere to get the same thing for less. I would advise to be careful with ths approach, because just like anything else, you get what you pay for. If someone offers the same thing for half the money, you have to ask yourself, what are they leaving out?
Let me know if there's anything I can do to help,
Ed
1. The power is adjustable.
(You can turn down the boost if it's more than you wanted.)
2.The turbos are expandable for future mods.
(You can turn up the boost for more power and the turbos will work well with future mods. ie. build motor, new intake, etc)
If you build a naturally aspirated 427, you are stuck with the power you have and will have to completely "throw out" the parts you invested in
if you want to increase or remove horsepower.
Go with a Stage 1 twin turbo first.
Drive it till the Stage 1 warranty is up,
then you can turn up the boost for more power.
When the motor needs to be freshened up,
build a forged 427 so you can REALLY turn up the boost.
You just bought a new car, so you might as well get some use out of the motor while you have the Stage 1 turbo.
Not to mention, there is no substitute for the power of forced induction and how it is delivered by boost.
Turbos are the way to go,
no matter how much you might love natural aspiration or hate forced induction.
Good Luck!

IN THE YEAR AND A HALF I HAD MY Z06 IT DEPRECIATED $30K, I WILL NOT M,AKE THAT MISTAKE AGAIN.. I CAN GUARANTEE THAT THE NEW Z06 WILL DO THE SAME... NOT TO KNOCK ANYONE THE NEW Z IS ONE HECK OF A VETTE , BUT I THINK FOR NOW I'LL KEEP MY LIG AND HOPE THAT IT WILL NOT DEPRECIATE AS MUCH AS THE 04 DID... AND I WILL DARE A NEW Z TO RIDE UP NEXT TO ME AT A LIGHT.. I'LL SHOW HIM THAT HIS 20K OVER STICKER COST COULD HAVE BOUGHT HIM A VEH THAT WAS WORTH 100K...
THE WARRANTIES ARE STILL VALID .. SEE THE MAGNUSUN ACT AND LIG HAS THERE OWN THAT COVERS ANYTHING NOT COVERED BY GM..
SORRY TO COME ACCROSS HARSH BUT ITS MY TRUTH ....
THERES MY THRUTH
YOUR TRUTH AND
THE TRUTH
I RESPECT THEM ALL

I think we better just stick to this is your truth, not the truth.
Because quite frankly your reasoning is flawed. Trust me the reason the Z06 has a fixed roof is to stiffen up the body. It is still a vette, as a matter of fact it is the fastest vette ever made. Now for your depreciation on your 04 Z06, if your 04 depreciated 55% off sticker in 1.5 years you did something very wrong when you sold or traded it in. That is not depreciation, that is called fu@#ing up on a deal. Now if you are counting mod money in depreciation, then of course, your car will sell for much less than you have in it. So will your moded C6. Here is the best formula to use for resale on mod money. mod money resale = 0. And it makes little difference who did the modding.A C5 Z06 bought new did not depreciate 30K in a year. Even if you traded it in, paid sticker you would still only depreciated at the most around 20K, 30K depreciation on an 04 Z would be 55%. Sorry, my friend this did not happen, (you better edit the "my truth" ledger), unless you just gave your car away, which is not the cars fault. I see you have an 04 Z06, well my brother paid 41.7 for his 04 new off the lot and he could sell it for at least 36K. That is only 5.7K depreciation. Maybe you bought earlier in the year and paid sticker for it, nothing wrong with that by the way. But still 30K depreciation, what did you get for your 04 Z, 24K. I wish you would have sold it to me. I hope you did not pay over sticker on an 04 Z06, if you did, you were the only one on the planet to do this. Now if you are counting your mod money in the depreciation I agree, mod money = 0 on resale.
Logically building the C5 Z06 because GM had FRC bodies in surplus does not make any sense. I highly doubt if all the 01-04 Z06 bodies were built in the same year, then stockpiled.
Or in 00 they thought they were going to sell 4 times as many FRC's and built too many. They build the bodies as they need them. Do you have a source for this claim or is it just listed in your book of "my truth".The 20K over sticker for the new Z06 is going to be very short lived, so I would not use that as an excuse not to buy one, unless of course you are in a hurry then I understand.
Just some thoughts for you.
One thing I do agree with you on is you should buy what you want.

Hey they are a business, they can not give things away. Warranty's cost companies money, they need to recoup that in the sales price. It is probably well worth it to many to have a warranty and peace of mind.




Heads and intake are available if you so choose to use them just as in the Z06.
If I had the Z06 with a removable roof, I would still rebuild the bottom end to fix what GM has once again dropped the ball with. As soon as I can buy the 7 liter block I will also have a 427 sans the bad parts.
Mark my words....as soon as that block is available there will be 427's for the same price we now see 402's for....less than 4k. ET performace heads and then you have a 600rwhp 427.....still capable of boost.

That was sort of the point of my post, you basically said you disagree with him that is what you are paying for. I myself did not.
I personally would want to use LPE also, if I did a major mod like a 427. Primarily because of the warranty. I think some of the other tuners are probably just as competent. But most do not offer 24 month warranties on their work.
Is LPE warranty void if you break it racing?
and as for the resale you were speaking of ealier, maybe its because in ohio many people cannot afford a vette, here in atl they are not a premium and there are alot of buyers, check kelly blue book and see for yourself, we can drive our vettes all year round, and they are not cheaper in the winter so dealers dont have to deal especialy when the next buyer is right behind you waiting to buy..... as for the truth thing .. it sounds like your a little bitter.. sorry about that.
the point is that either way the lingenfelter is not just a name they did not make themselves known and get inducted into the corvette hall of fame for no reason.. they are known for there quality and there performance. and some of us work for a living THE CAPS WERE BECAUSE I WAS ON A PLANE TYPING FROM MY PHONE..sorry if reading in caps is difficult for you.. i hear hooked on phonics works really good ..
