engine replacement advice request

I am started to believe this might be a case of planned obsolescence.

How many people will buy another vehicle?
How many will buy the same brand as brand loyalist ??

I would think over the many years and probably thousands of lawsuits that discovery would uncover some email chain or document actually discussing "Planned Obsolescence" but it never materializes.

What materializes is incompetence.

I had a good friend that was a former AMC guy. He was older and couldn't do and thing difficult. I was youngthen , so he asked me to put a new clutch in his Renalt Alliance. It was an AMC/ Chrysler product if I remember. First for me back in 1988.

Renault had AMC make it in the states so Renault could get a foothold. Mid-80s.
Chrysler agreed to buy AMC in 1987.
My 87 Comanche had both AMC and Chrysler decals under the hood.
Last AMC car - an Eagle, rolled off the line in 88, the 1988 model year. I used to know who owned that car.

Naw, that's another one of those things like the engine that burns water............
Again, the cam issue is a tiny bit in the whole scheme of things, the millions of Pentastar 3.6 out there. When there's 20,000,000 engines, you are going to see some numbers as far as repairs.

 

[ShadowsPapa]

Well, with the fact that cams are being ordered and back logged at rates never seen before upwards of 12,000 and that there is no way that all thise cams are going into gladiators alone.

8 years of the JL (what, 200,000/year?),
5 years of the JT. Yes, likely in others as well - I've heard of a few in the Ram trucks.

I want that 20hp

If you live near a shop that does hemi swaps, a lot of times they will have engines and transmissions they've pulled that are reasonably price. Example below.

Was going to say the same thing. Not to mention that our 3.6 is used all over the lineup. Some soccer mom’s mini van that’s been in a collision would be cheap.

. My mother-in-law had an Eagle. She still talks about it.

I had a couple friends (they were brothers) who would do a sort of verbal diagnosis (they debated about what failed) of mechanical problems in their cars back in the day, rather than actually do the diagnosis that would tell them for sure what was wrong. Of course, I could tell them what was wrong with their cars, but they didn't believe that their cars being Ford products was a real problem. Kinda like taking a problem to the internet to get the most accurate possible diagnosis, instead of finding a trusted shop to do the work.

Very early on, in fact, still in HS, I got the reputation as a "troubleshooter". I took on jobs where others had failed to actually resolve the problem.
Our high school auto instructor saw that in me and groomed me for the contest, and challenged the heck out of me by deliberately making things not work to see how well I could figure them out. I loved it. It's how I got my second shop job, my first out of college - walked into a shop where the service manager was getting very frustrated with a Ford he was working on (he was a "Ford rules, everything else sucks" sort of guy. Bad time to walk in and look for a job...... LOL
He had it on the scope and had been struggling with it for a while. We chatted a bit, then he said take a look at this engine, the scope, and tell me what's wrong.
I did - checked some things out and saw something in the pattern and pointed it out and gave him a suggestion. It worked - he said "you start next Monday".
I didn't even need to use the letter I had from Plymouth Corp stating that if I walked into a dealership looking for a job they should strongly consider me.

Fakebook groups drive me nuts - "why is my battery dead" - answers range from "probably the regulator", to "you need to replace the alternator" to "it's the engine to chassis ground" to a few other crap guesses tossed in for good measure. No one even says "have you checked the voltage at the battery with the engine running" or "what's the battery voltage with the engine off", none of that. It's right away into stating it's this or that part, to instantly suggesting replacing parts. (in one case, the battery was fine, the starter was toast!)

(Happens here, too.......)

I believe the 285hp to 305hp, that measly 20HP could be attained through many means also exhaust cold air intake etc...

LOL - that's funny. CAI - HAHAHA.

Exhaust - maybe with good headers tuned for that specific engine.

Saw a dyno report from a guy building a nice performance V8 and ironically, he INCREASED HP by a large amount by swapping the brand and type of headers from large tube to SMALL tube headers (and a different Edelbrock intake manifold).
He said the header change alone gained several HP

If I thought I’d gain 20hp, I’d put custom headers on this gutless turd.

Good luck - the exhaust "manifold" is part of the head. No manifold to remove. Otherwise, I bet there'd be a huge aftermarket for headers for the 3.6

If they wanted, I'd bet they could squeeze 1 or 2 HP out of these with an exhaust port redesign and some head mods.
But the exhaust design on these is extremely short, pretty equal length, and very short to the pipe.
Not a lot to gain here - unlike the free-flow exhaust of the 1970 AMC, and the dogleg exhaust port. They gained a lot of HP just by reshaping the exhaust port and smoothing out the exhaust manifold flow.

You can pick up 41hp and 35 ftlbs with just a tune from livernoise and even with the pcm swap it's easier than installing a set of headers. If you're willing to run e85 you can pick up 50hp and 55 ftlbs. Why anyone messes with bolt ons before a tune on these vehicles is beyond me.

If I get back into the Gladiator platform, barring a factory Hemi option, I'd seriously consider buying a good condition used one and doing this.
I know it's a lot of money, but in other ways it really isn't.

The LX3 would be sick. Find one with a blown v6 for $15k or less and it would be cheaper than buying a new one.

Another 40-50 ft-lbs of torque would be nice too………
