Like I said before in another post, if this block is produced, the increased bore size alone will put the LTX on equal footing as the LSX if not better. So many good cylinder heads out there with bigger valves and bigger bore will just uncork power.

 

People don't get it that swapping an LSX isn't cost effective. Too many things you can't 'reuse' and aren't compatible.

 

Agreed. Tony Mamo did my heads and intake. I already have a quote for reworking my heads and putting in bigger intake valve to take advantage of a 4.155 bore just in case this block actually happens.

 

Holy Zombie Thread revival!!! You type the above but are jazzed about buying a $5,000+ aftermarket aluminum block? Huh? People in this old thread shitcanned their OPTI and whole OBD1 setup and went 24x / 411 pcm / LS Coils for a reason. If you bought a bone stock '94 Z28 I'm not seeing the logic in saving money by tearing out the electronics, the engine, and going aftermarket dedicated LTx block which doesn't yet exist. Unless you believe that you'll make comparable power to an LS by building a 383 LT1 and using Tunercat or such?

This isn't meant as a personal attack btw. I'm just confused when people who are hyped about a possible aftermarket block are the same ones saying staying LTx is cost effective in an era where virtually nobody is proving this to be true from a performance per dollar standpoint.

 

But but but then we could run super high dollar big heads!

Annnnd still get beat by a JY SBE 5.3 with a cheapo china whirly boi.

 

Wondering how this block would affect f-body specific race classes...

 

Why do people spend $70,000 on pro mod engines for a 7 second run with no $$ returns? Or spend 10's of thousands of dollars worth of car to sit in a trailer only to come out a few times a year? Car enthusiasts spend endless amounts of $$$ and the only thing they get in return are bragging rights. And you come in here and question people's loyalty to a certain engine block? It's almost an insult to car enthusiasts in general. You should know better. Anyone should.

 

I just want another option that gives us the ability to make more power N/A, N2O or Boosted. A stronger block that allows more cubic inches or comes in aluminum or both and maintains LTX architecture helps do that. I have nothing at all against LS engines, nothing... I just simply want to keep the LTX in my car or the best option of it. It has nothing to do with spending money or saving money but I will say this, I'm very tired of all the LSX guys and their talk about how LTX engines can't get the job done when they have about 4x more the aftermarket to work with than we do.

 

I agree with this as well. I'd also pay for an aftermarket big bore block for the same reasons. I already have good heads, forged bottom end, etc, so just having to swap pistons and cam to gain more power and torque for the same RPM range would be great. Not all of us want to start back from scratch with LS or Gen V LT, or want to go boosted or big SR route to make more power.

 

Exactly. I have a Hellcat and a heads/cam Magnuson C7Z and I still love how my Camaro runs and sounds. Weight savings and taking advantage of a bigger bore would be sweet. I already have a price from Tony Mamo to rework my heads for a 406 if this ever happens.

 

Yeah.....why not just sell those things off?

But I agree that the LS swap isn't the hot-shot a lot of people think it is, goin' in.... Either you go cheap with a stock(ish) 5.3 and make what a heads/cam LT1 makes, or you go strong with a LS3 and pay the price of two strokers.

Lucking for me that I had a low-mile LS3 on hand when a dropped a stroker into my SS.

those who spend the kind of money you’re talking about are well established and have **** you money to burn, or are sponsored in some way, or perhaps morons who are deep in debt. Not sure how anything he said could be taken as an insult.

 

What defines the LT1 in your mind? What exactly? The things that define it is what you'd keep on a new "high zoot" aluminum LTx block? You'd run an OPTI? The LT1 or LT4 intake? Please clarify. If you have no OPTI, run Dominator ECU, and have a sheet metal or carb style intake you're not really LTx unless the provisions for OPTI and water pump placement are all that matter.

People spend $70k because they enjoy it and can afford it. Want to get rich? Don't get into racing. People will put a 2JZ into a C5 'Vette or spend money on a Coyote swap instead of going LS; that's more inline with your concept of loyalty IMO.

 

Edit: Don't know why I'm even entertaining the troll.

 

PSA, its 2020, no one gives a flying **** about LS1s anymore.

 

I think you answered your own question when you said people will spend the money because they enjoy it and can afford it. That’s why some of us want this to happen.

 

I forgot all about having to deal with intake issues. My cheap *** would most likely run a LTx intake and have a power/torque curve like an L98.
Exhaust, too. I know there are 1 7/8 stepped. Is that enough to accommodate a big cube, high rpm monster...

 

He's a stereotypical LS nut swinger. He should go hang out in the mustang forums and convince everyone to swap out their coyote for an ls.

 

I usually don't bother with LSx smugness. More often than not, you go check these guys out and find zero pics of them doing anything under the hood of... anything. Safe in the comfort of their purchase of someone else's engineering effort. Making good power from honest thought and effort of one's own with something older and 'less desirable' is just too hard and takes too much time. I've posted some stuff to youtube for TBI SBC mods and OMG LSx nutswingers come out in droves and comment about LS swap instead, coulda done cheaper, blah blah blah. I go look at their channels and there's zero to be seen. It's like "I don't know either platform, but I read that it's a fact that LSx is better so I'm comfortable criticizing you from the seat of my laziness and ignorance." Not saying that's this guy, but that's been my experience with LSx proponents that butt in on LTx discussions.

And yeah, I'd jump on an iron big inch LTx block myself for a NA build.

 

What simply defines an LTX to me is the water passages in the block that require LTX specific heads or heads modified to work on the LTX block and obviously the one off water pump. I don't care what you use for ignition or intake manifold, etc etc. If the block has LTX architecture it's LTX.
