LQ4 Power

[lionelhutz]

I guess these old 350s are just garbage and don't work in their intended environment or work efficiently LMAO!!

[sarcasm]Yes, obviously the engineers at GM are complete retards because they set back their engine development by 80 years when they abandoned the more powerful and better on fuel small block for their LS engines. Everyone else who's swapping them must be retards too.[/sarcasm]

Sorry, but a bunch of your claims are BS. You're not taking a $2600 budget and putting together a small block and running circles around this engine below 5k rpm with a 215* duration cam. If you put together the right combo then you could approach the same power with that size of cam, but that's about it. You're probably also one of the people that claim the 90's LT1's had more torque and was faster than the LS1 too....

Skinny Pedal showed a very potent engine you can build on a budget. I give him a big thumbs-up for that and an even bigger one once the cam info is available so others can duplicate what he did.

Thanks. We are working on putting the cam kits together. The cam has less then 215 on the intake and a little more than 215 on the exhaust.... Lift is relevant to cathedral port head. LSA is very tame, between 114-116 depending on displacement.

As far as 2600 goes thats whats in the engine. Not the exhaust, tuning, tuning software, my underwear and on and on..... I tune for a living so all my tuning equipment is very paid for. I am not a vendor on here, so I have no intention of pushing services or product. I do post up rigs/projects here and there I think some of you may find cool. If people think I am boasting, its not my intention. I'm always open to constructive feed back, not crap or total disrespect for no reason.

Also a fun note. Stock truck exhaust manifolds flow plenty of air for this kind of power, PLENTY.

If they flow "plenty" of air then why do these engines gain 20-30 HP from long tubes???

Your tune needs work, maybe? All long tube manufacturers advertise those numbers.

Hey, buy my headers. You will also need an engine tune...... WOW 30hp after headers aaaannnnnnddddd a tune.

Its a tuning site, we know what happens when you move the O2s further down stream with long tubes. Well, what needs to happen anyway.

Honestly in open loop or PE not much at all happens from the o2 placement. My tune is just fine and my part-throttle air/fuel ratios are right where they should be. I have been tuning long enough I know how to fix the tune and adjust the transient delays for the 02 sensors as well as the proportional gains and durations.

I guess I should mention I got a 6.0L with a bent crank snout and a broken compressor mounting boss cheap today for those that think I am anti-LS. It is destine for a lightweight sports car where its potential can be realized.

I think it was funny that someone complained about my L31 using the 0411 PCM. Its alot better than the LT1 era PCM that my engine started with and it alone was responsible for a noticeable fuel economy and driveability gain over the black box. I am about to dip further into LS components and install the EFI Connection 24x kit on the old L31 and possibly drive by wire if I feel like digging that far into the harness.

You may also notice where GM did not have the US emissions laws to contend with they kept the TBI engines well into the OBD2 era and kept the old L31 well into the GMT800 trucks. You can buy 2004 GMT Silverados in Mexico that have the 5.7 L31 from the factory. Its definately not a bad engine and certainly cheaper for GM just couldn't pass our newer emissions standards.

I'm done. Circles are round and this one will keep that shape. An inevitable loop of awesomeness is sure to ensue. I think I have a better chance at hitting 200% NA VE than making headway in my own thread.

Edit

I have to ask. Do you have some type of impairment? It would really explain a lot and make me feel somewhat bad if you do. Its just that the way you are replying and the way you word things has me thinking something has to be up. I understand we all get fixed on some things but not to this extent.

This makes no sense. With your BS claims about easily annihilating the torque of a LS engine below 5k using a cheap small-block build, why would you want to run a LS engine for any street use???

Dyno queens aren't that fast on the street and often not that fast on a track either.

Who said it was going to be a street car???? Its getting a TH400 with a ~4,000 stall and 4.56 geared 12-bolt with a big Holley on top in a ~3,000 lbs car.

I think only a handful of people truly understand this and I've yet to find folks willing to share their knowledge. Perhaps you could visit Barry's "Idle BLM" thread under "GM EFI Systems." Several of us are running the 7427 ECM and could use some help understanding what changes are needed to eliminate surging when running headers and larger cams.

Gentlemen...

A disagreement of opinion is fine but please keep it civil.

Thank you.

You can not pull that out of context. When you pull the single question without the rest of why, it forms the problem of civility.

Actually I am and doing it with a stock 12cc dished piston shortblock and ~9.5:1 compression ratio. The old Gen1 engines INCLUDING LT1 make more low-end and midrange grunt than stock LS engines.

215/220 cam is more like a 218/224 with the 1.6s.

[lionelhutz]

Yup, I knew that you'd even have to argue that one. The stock LT1 torque curve is lower than the LS1 torque curve through the whole rpm range. You are completely delusional.

Oh wait, you're probably comparing a stock LS1 vs a built LT1....

You are mistaking on the LT1 vs LS thing atleast LT1 Vette vs LS1 Vette. The LT1s put down a better 60' because they make peak torque at a lower RPM.
