A big THANK YOU to everyone participating in this post so far because it's been an
extremely entertaining read. What was said two or three times that is the most
significant point of it all is "attention to detail". When you are in a class/group
that is so similar (i.e. not the stripped down trailer queen club) with street cars
that some daily drive with bolt ons and H/C combos that are similar, all that is really
left is the details.

There are 100's of details for a 93-97 LT1 f-body that can all add up to some major
improvements or go the other way and work against you. For me, since I can't drive
worth a crap, and I don't wan't to get into all the M6 upgrades necessary to produce a
decent 1/4 mile time I'll just have to sit back and read about it and enjoy my dyno
queen that is a total blast to drive on the street.

Anyone running low 11's with a full weight, streeable LT1 is doing one hell of a job and
it's an admirable accomplishment. My cousins 1966 L88 Corvette with 4.11s on 10"
slicks would run 12.1x back in early 1970s and I thought that was unreal. Here you
are doing better with daily drivable cars that probably get 20+ mpg on the highway.

I don't have a recommendation for the original posters question other than the options
do not seem to be comparable to me. A 211/219 cam is a different animal than a 22x/23x
cam so the H/C combo would be quite different. As with my setup which is a 210/224
cam, I did not want or need 200cc port volumes so I went with 185cc. If I had a
383 or a cam that would make power above 6k then I would want the 200cc ports.
I would think LE2 heads are probably closer to 200cc and the LPE package is
probably 185-190cc. The main difference is hand porting vs. CNC porting. CNC ports
will typically be much closer to the target volume and to each other (just another
detail). If you are searching for .01 seconds, details are critical.

 

You are giving me lists of those w/ LE3's and 383's and those which don't disclose race weight.
There are only a select few of those which are comparable to a 211/219 cam and yes they are running good numbers. I was wrong to jump to the conclusions there aren't "any..."


I went back to that link and did not see anything regarding your name or car from page 9 on, so what am I supposed to be looking at?
You weren't lead to believe anything other than what you chose to believe. I'm not sure how you came to believe it ran 12.00, but nonetheless, it's still a 12.0 no matter how you look at it.
Yeah I remember you giving the "variables" speech and I think I remember telling you that not everyone w/ an LE/BRE package lives in the Rocky Mountains. I'm sure there are others who live at sea level tracks. You think?
My junk also ran a 12.28 @ 114.2mph at the Texas Motorplex which is somewhere in the 600ft. ele. range. It ran a best of 12.21 @ 114.5 at MIR. After the 4.11-to-3.73 gear change it ran the time that you were mislead to believe.
Yes I know there are variables, so on and so forth, but for the sake of argument and the plethora of LE/BRE 400rwhp cars turning mid 12's @ 110mph....
Within all these threads, not sure where to look for your info on your car.... do you have an auto? What package are you running? Specs and race weight?

 

Well I'm glad you learned how to round numbers in grade 4, 12.09 is a lot closer to 12.10 then 12.0 but anyways.

My timeslip and weigh ticket is at the bottom of page 10 in that link. Car was M6 with 3.90 gears and 3800 lbs with me at the wheel. LE2 heads BRE emission cam which passed no problem. First time out with that combo I ran 12.73@110mph which is where most of the cars you speak of are at. I put in the time to work out the bugs to run a best of 12.14@115 mph at 642 ft.

 

And the car ran a plethora of 12.1's and 12.2's. Christ you dramatize this like I'm trying to hide something. It was your decision to set yourself up for disappointment. Regardless if it was a 12.0999999 it was still a 12.0 run, correct? I figured that combo was exhausted and have since moved on. I thought all this head porting "technorogy" has advanced since 6 to 10 years ago?
Now that wasn't too hard was it. Congrats on the 12.14. Perhaps at a sea level track you would be in the 12.0 range if not a smidge faster.
No dyno numbers? No cam numbers? Duration? Lift? LSA? Or is this one of those sooper secret things?

BTW... this combo was on my car for 70K miles and never did I have one ounce of problems the entire time it was on the car not one LPE component needed to be serviced including the springs. It ran 12.low strong until the day I change up.

 

First two are under 114 mph...great et, and set up pretty well. 380rwhp = 113mph? Props, and now you're name-calling? Give me a break, jackass.

 

come back and brag when you trap 120+. nice job on working the ET down though...

 

There are cars making a whole lot less power running quicker ET's than most on this site - are we not talking about making power?

 

Thanks for the advice.
You're right though...let naive and mediocrity be. It's not my money they waste. Why listen to Lingenfelter, he didn't know **** from shinola anyway.

 

Well stated, Mike.

 

 

Does LPE still produce ported LT1 heads? Any idea how much they run, cost wise, if they do? Anyone ever talk to them about different cam options other than the 211/219?
Don't mind me, just day dreaming here. Carry on!!

 

They are courteous enough to know you don't need six thousand different emissions legal cams that produce the same outcome as some cams even with larger profiles. If you want something different they can have it ground for you.
They deal in street packages which are emissions legal everywhere. Most, if not all of their street engines have an EO number.
As far as pricing is concerned... see what happens to any shop who becomes as big and is as well recognized. You should know you get what you pay for. Don't think you have any room to post up about cost/performance.

 

SS RRR, what's with the last sentence? Having another bad day? I'm just looking for a little info, and whether or not they still work with the LT1-LT4 packages.
And which is it, you can't beat the 211/219 or they can spec you another cam that might better serve your desired results? But wait, some larger profiles might not preform any better than one with a smaller profile. Really? Thanks for the hot tip. I sure hope I didn't screw up with this huge cam I have.
Cost verses performance? Lets talk about that when and if you have some track #s from this decade.

 

I gave you a quick rundown a 3 minute search, and almost everycar on that list is close to full weight judging by what was said in the threads. You still have ported LT4 heads, not regular LT1 heads....everyone knows there is more performance value offered with LT4 heads. So some of the larger cammed cars that run quite similar to even out the use of LT4 heads. Maybe you could show me a list of people running the 211/219 in a full weight M6 running similar times as you? I mean your acting like you setup is the one to compare to, show me how many there are.

Plethora of LE/BRE setups running mid 12's@110....I posted every single LE results found in that 3min search. None were left out because they weren't fast enough...so where are all these cars you speak of? You know about all these cars that I posted about because the funny thing is, You and your brother posted in virtually every thread. Many turned out just like this one.

 

I don't believe it for a second. It's just more indirect instigation which you've posted so many times before.
You are arguing about nothing. If you want a cam spec'd they'll be happy to point you in the direction necessary. If you want your heads ported/reported they'll do that too. This is exactly what I'm typing about... you argue based on nothingness.
New engines are expensive to build and take time to work out unsuspected things. I've been living life with my family and working on our new house. This engine has been in the making for the last 4 years. It's hardly a priority. You just might unignorant yourself if you were to ever do so. Is this more indirect banter about how you believe my setup is a joke as you've PM'd me dozens of times now? How it doesn't exist? If not then really, what do you want to add to this debate? The fact that you're barely in the 11's N/A w/ all the crap you've done in an auto? As said.... you have absolutely no room to post about cost/performance w/ what you've done.
