Good point. My guess is the last new development Lingenfelter's or Automasters have done on LT5 performance enhancements came in the late 90s/early-00s.

And, yes, I get the implication in your question, but, to me, it seems, maybe, a little bit arrogant. I suggest that it's unlikely you'd be where you are now had those folks not done their "20 year old stuff."

Ya think your attitude might sour potential customers who are outside of your flock of admirers here on the Registry forum? Much less get someone connected with media interested in your product?

On the better oil control how does the closed deck effect this?

Good question which I can't answer. I stated earlier that I based my belief on what Haibeck said to me in an email. I have not personally tested a closed deck LT5 for oil control but, I do put some faith in what Marc tells me. I've known him for a long time.

Most stock LT5's have oil control issues.

Thankfully, mine does not...at least, not with the way I drive it most of the time. I suppose, if I was tracking the car and running laps such that the engine spent lot of time above 5000 rpm, I probably would. Currently my oil consumption is about a quart every 8000-miles. In the "old" days, when the car was a magazine project, we put about 100 dyno passes, maybe a dozen or so drag strip passes and several track days on the car, but nowadays, it just gets run hard on the street.

We have 3 done with no issues of any kind,they drive to BG every year, race and drive back home.

Three trips from DesPlaines to BG and back cruising on the highway along with, say, fifteen or so, 11-sec. drag strip passes. I take it, I'm to accept that as demonstrative of good durability and oil control superior to that of "20-year old stuff"? That in mind...I'm curious. Have you run any GM durability test schedules on the engines you build?

Why do you wanna do a 368?
Is stock motor blown/broke?

Nope. There's nothing really wrong with it other than 60,000 or so miles and 15 years in service. Ok. I admit that, of late, my oil use has gone from about a quart every 10,000-miles to a qt in 8000-mi, so maybe I need stem seals. Mainly, I just was thinking of updating the engine but, admittedly, I want to do it on (as someone else aptly stated) a "beer budget."

Technology moves on,if you don't move with it you'll be left behind.

I submit: if you truly believed that, you'd be doing LS7s.

I find this response out of line for the question Pete has asked. Pete and the FBI Crew have been on the cutting edge of the many LT5 improvments. These guys are running some fast reliable Z's. Most members here would not hesitate to hand their cars over to them to work on. From what I have read in the posts the only thing these guys were trying to do was help you maximize your performance dollars. Its your car so its your call, but remember you asked the question in the 1st place. Good Luck

I do not do the closed deck it's done by AES anybody can call and get it done.
I'm not selling anything.
When i saw the crazy prices on LT5 parts i went out and found/made lower cost replacements and were initially made for myself but if anyone wants what i have they are welcome to them.
Basicly i don't care where or who does your motor the advise i'm trying to pass on to you is not worth doing a 368 for the money.
I know it's your money and you can do whatever you want with it but you came on an open forum with the question did you think everyone was giong to agree with you?

Because someone disagrees with you does this mean they have an attitude.
If you think you won't like the answers i suggest don't post questions on a puplic forum.

Question right back at ya, has any other tuner done durability tests?
I will need documents from GM on the durability of the 368.

Well if five 1000 mile trips,racing her hard,driving in Chicago traffic is not good testing,what is?

We try to do testing on parts as best as we can without having to spend millions of dollars and thousands of hours, Jerry tested his head gaskets did he spend millions and thousands of hours i don't know,i was satisfied with his testing and i'm using his head gaskets will they hold up
200k miles i don't know i'll post up when i get there,so far they held up to 4500rpm clutch drops,
130mph 1/4 with some aggresive street driving,good enough for me.


Man if you use 1 qrt every 8k miles that is one killer motor i would not touch the short block,there i go again disagreeing with you.lol

LS7 pushrods been around since caveman.

The only attitude i have is because i'm not a yesman.

You asked i replied maybe you didn't like the answer so i have an attitude.
Oh well,lifes too short.
Eitherway enjoy your choice.
Pete

P.S.
For those that know me know i love the LS7/LS9 the reason for smiley.

Hey Hib, Pete's Greek, need to cut him a little slack

I have known Pete from BG and here, bought some of his parts. He is a stand up guy. He has spent some time and a good deal of money on cam research, and has come out with good stuff.

The tech comment... LS7 has more technology? I own both. The LT5 has better tech then the LS7. We all know multi cam and valves out does a single setup.
Didn't the last LT5 design ( mid 90's) make 550hp from 350ci. LS7 is 505hp from 427ci and dropping valves....

[ZZZZZR1]

Hib,


If you knew Pete, you would want his advice.


Looks like you are set in doing the 368! Go for it and I'm sure you will be 100% happy with the end result.


No doubt barney will be in a magazine by this time next year

Please keep us updated and look forward to see it!

Pete,

You don't need to justify yourself and your capability to anyone on this forum, especially anyone that doesn't turn their own wrenches.

I'm with you, Ricky. Should I, Could I, Would I.... sounded like an invitation for feedback and he got it from one of the very best, gratis, no charge. What a smartazz.

I'm extremely happy with the work Pete did for the Turq Monster.

Might sound like a stupid question but when your talking about 368 is that a LT5 punched .020 over ? Or is that the street skinner package ?

It is an LT5 with 4" sleeves instead of the stock 3.9s.
