LPE top end package
I am getting close to have this package done to my car. I would like to hear from some people who have also had this package done to their cars. What did you think of the before & after results? Would you do it again?
thanks,
Scott

Re: LPE top end package (sacarmic)
You will not get alot of replys to this because LPE will only put a GT2 cam in it which is small and for a good reason every day torque in low rpm driving you will not get the high make that really high #'s that others claim with the cam and heads, which happen at 6000 plus rpm.
Why do you think LPE does not do the same (install large cams for street use) because he looks at modding the car for specific use, now the question what do you want from the car, if it is strict drag racing then you have to build it for that with lower rear gear and bigger cam with big sticky tires, and get the car into its range and keep it there.
Now for street and or auto-x and solo 1 i think that low to med torque is what you want, the here and now power not the wait till it hits it's range big cam power.
Do your self a favour and get dyno 2000 softwear and try different cams and see the range of torque and hp and see what works for you.
LPE disigned the ASA motor which uses the 226 duration cam so he does use bigger cams but for specific applications, call Tim and tell him what you want form the car and see what John would do.

Quality- A+
Reliabilty-A+
Drivability-A+
Value-C The difference in SOTP feel is simply not great enough--to me--to justify the expense. Had I to do it over, I would go with the magnuson or a stroker.

Re: LPE top end package (sacarmic)
I believe LPE feels 430 or so flywheel hp is all that can be gained on a H&C upgraded LS-motor without dipping below HIS STANDARDS for everyday street drivability. Because of the serious labor involved, it's hard to build value into this UNLESS your criteria is (A) extensive road racing (engine lives longer than a power adder mod); (B) also lots of daily street driving, where drivability comes into play; (C) some striaght-line street play. If straight-line is the game and less road racing while maintaining virtually zero-compromise in drivability, the LPE-Magnuson S/C is one of the best values money can buy.

Re: LPE top end package (sacarmic)
sacarmic --
I think some here may be underestimating, to some extent, what the LPE Top End Kit can deliver -- see my sig for results from a Top End Kit, with LS6 heads and headers, that was finished just before last Xmas (of course, 397.8 rwhp/.85 = 468 bhp). Also, they have since moved to a newer cam that makes a few more rwhp.
Before my current C5, I had a bone stock '01 MN6/Z51 Coupe -- the SOTP is night and day between the stock '01 and the LPE '02 (not to mention that the LPE '02 sounds really good, much better than the stock '01 -- I understand heads and cam cars, especially with headers, tend to be like that).
There's another LPE option to consider that wasn't available when I had mine done, the Magnuson supercharger -- similar cost, (somewhat) more bang for the buck (though I suspect I'd still go with the Top End Kit even now, given the sweet sound of the heads and cam engine, the aftermarket hood I don't particularly prefer to the stock hood, and the [small] parasitic loss of the Magnuson supercharger that would have a [small] impact on highway mpg which I'd prefer to avoid).
Anyway -- I like mine! :yesnod: :yesnod:

Re: LPE top end package (CJS)
NBMDVM, What kind of rwhp do you think this puts out, at least 400 rwhp,right? What is the expense? Same as the blower set-up?

Re: LPE top end package (NBMDVM)
NBMDVM,
may I ask what tranny you have? Tim at LPE, said there would be a big difference between the auto and the stright. I have the auto, that's why I ask. When did you have it done? Those are lower numbers than I thought, they said around 380-390 for my car.
tornado,
are those LPE ls6 heads or stright ls6 heads? They didn't mention that option to me. Interesting. :)

Re: LPE top end package (sacarmic)
I have MN6 and 3.73's. Also, you will get more power with the ls6 heads, but plan on spending an additional 1500-2k for them. I had the package done in March '01. 365rwh=433fwhp so I got what they advertised, it simply doesn't feel like a huge sotp difference to me. The car will break the tires loose now at ~5k in first and gets loose on a hard shift to second--which it would not do before, but I've driven it back to back with a bone stock(not even an aftermarket filter) '99 and the difference, TO ME, is not enough to justify the cost. You're results may vary. If you're ever down my way, I'd be happy to let you take a spin before you make the purchase.

Re: LPE top end package (sacarmic)
sacarmic -- LPE-prepped LS6 heads; I was told they'd probably be worth about 10 rwhp over the LPE-prepped LS1 heads
with or without the LS6 heads, be sure to also have them install the '02 LS6 PCV setup (one in the valley, as v. two consisting of one under each valve cover) (eliminates one of the two major causes of LSx oil consumption)
