Would a Golen 383 with P&P heads w/aftermarket valves pass emissions and what HP?

 

Thanks for all your input guys, but it looks like no one here has any personal experience with Lingenfelter LT1 packages. I've been around awhile and have investigated about every option possible for my car, from turbo, supercharging, nitrous, and normally aspirated. This is my 2nd LT1 Z28, and I've had this one since 6/02 and left it basically stock until I decided what direction I wanted to take it. This 96 Z isn't my daily driver, and is only out on nice sunny weekends. I have no desire to take it to the strip to eek out every last 1/10 of a second in the 1/4 mile and risk blowing up the motor I invested so heavily in. I want to have a reliable turn key driver that starts and runs reliably and would like to have similar horsepower to todays Camaro's, Challengers, Mustangs, etc.... but without paying $40,000 plus to do so. My car is paid for and has been for quite some time. I've learned in the performance world, and like most things in life, "You get what you pay for". I realize there are cheaper ways to get serious horsepower.... initially. By the time you factor in the added details like tuning, labor, time, and other necessary modifications, the cheapest way FOR ME isn't necessarily the best way. I am out of town on the road most days of the week and when I'm back home I have no desire or the spare time to spend hours and hours in a garage wrenching on my car, trying to make my new mods work. I'd rather be driving it. I'm 53 and in my younger pre-family days, I changed many motors, transmissions, rear ends in my old muscle car days ('69 Trans Am) in the early 70's and have no desire to do that again. My initial question wasn't can I make more horsepower cheaper than a Lingenfelter package. I'm more concerned with drive ability, and reliability at this stage of my life..... but still like to bang a few gears with some decent horsepower when the occasion is right. I read on here all the time about some of you with your projects working all weekend to trim off a couple 1/10 of a second and battling the details of computer issues, parts breakage, compatibility issues and I'm really not into that these days. It's great you guys have the time, desire, and abilities to do these things, but I don't. If any of you have any input on someone that actually owns a LT1 Lingenfelter package let me know. I may still consider some local talent if I find someone with the LT1 experience with references. Thanks for your time.

 

Golen puts more effort into marketing than QC, and has a "happy" dyno that puts out inflated numbers. Just find a local builder before using them. Only real difference between a gen 1 and LT1 far as an engine builder is concerned is the appropriate compression ratio. Once you get a gen 1 builder to accept that an LT1 can tolerate and likes more compression you are all set.

 

Sounds like you had your mind made up before you even asked the question, so it was really sort of a waste of time.

No one was any experience with Lingenfelter, because no one wants to spend that kind of money. Suggesting that spending less will result in an engine that blows up when you take it to the track is naive.

Its your money... spend it any way you want.

 

Thanks. That was really helpful

 

I'd say you're a good candidate for what LPE has to offer. Their product seems to fit your wants and needs well. It's really not a product for the thrifty, DIY minded person that this board is mostly made up of.

 

Agree.

OP: if you really don't care about the money, go for it. I am pretty well situated financially and am not a bottom feeder in any way. I spend pretty big bucks on my cars and have no problem spending for real quality. But the idea of spending at least $5,000 just to have the Lingenfelter name doesn't sit well with me, that's what we (or at least I) am trying to express. I don't like to be "taken", which is how I would see it. YMMV.

I do have some experience with Lingenfelter engine packages. Two of them (Corvettes) have been in my buddies shop. They were nicely done and did what they were supposed to. Absolutely nothing magic about them. Both were there because the owners wanted more performance though!

If you look at what I said Dwayne. My "quote" was for the engine only. I then said you could spend the other $3-4,000 towards other goodies like suspension, drivetrain and dyno tune. I figured he already knew that when you upgrade your engine you need to upgrade the fuel system since he has over 900 post. If not you will want to upgrade your fuel system with a 255lph in take pump and larger fuel injectors probably up to 42lb. This will run another $6-700 dollars. CAI would be in the $6,000 "quote" and you can build some true duals for around $500 with headers. None of my "quotes" include shipping and are all if you do it yourself. I know $10,000 will get you the 450 rwhp because I have done it. As far as shops go in Dayton look into kammer and kammer or performance clinic. I have delt with both and both do good work and have plenty high quality muscle cars running around.

 

I agree with Fred. It seems this has been a waste of time. You obviously know what you want and what it takes to build LT1's. As far as Lingenfelter goes I would not spend $10,000 on a engine for the name especially with the low amount of power compared to other builders out there like victory etc. etc. And as far as the warranty goes if you build it right and build it with the right parts you shouldn't need a warranty. If you keep up on your engine you should be fine and if you want to go out and trash it then the warranty might be suited for you. I have ran my car hard since the first start up and I have had no problems at all in the two years since I built it.

 

Guys, don't be so hard on him. For that 10K he is also getting removal, re-install, and a dyno tune too..... I think that was what caught his eye too..

 

"Guys, don't be so hard on him. For that 10K he is also getting removal, re-install, and a dyno tune too..... I think that was what caught his eye too.. "

And with a CARB number he can pass smog in CA. That little bit of info has me interested as well and I'm a cheap *** bastard.

 

I am in no way hating on him or Lingenfelter. I am just saying it seems he already had his mind up as to what he wants to do before he posted this. I understand he want's feedback on the Lingenfelter brand, but I mean the name speaks for its self. You can give me $10,000 and I will do everything they are doing (Except warranty) and pocket $5,000 or so. I am now opening Sebastianfelter Performance Engineering. J/K But seriously send me your engine and $10,000 and I will take care of you.

 

ABA383 on ls1tech has a ligenfelter LT1 thats been going string for years, hit him up!

 

I live 30 minutes from Lingenfelter and had a buddy who worked there for 2 years before he went on to work at Procharger. Lingenfelter makes excellent engines and also backs all their work. You need to call Lingenfelter and talk to one the sales staff about what your goals are. Their website offers that package which is a basic setup, but you can do some custom tailoring depending upon what you want and still retain the warranty. I highly encourage you to give them a call! Good luck!
