Exactly Joel.

HP/Liter is ricer math and is pretty much useless.

 

Look at the Ai cars, I have never agreed with the posted power numbers they SAY they make on the dyno. But they ALL run VERY well at the the track, Why? Attention to detail and the RIGHT components. And a COMPLETE setup all the way down to suspensions and sorted combos.

If you are gonna copy someones setup, you gotta know ALL of it and copy ALL of it to make the same power.

Intrau made a 1500 HP turbo setup on the stock block, there are 850-900 hp Turbo/Supercharged LT1s floating around.

Its all about HP per dollar, to me anyway.

 

haha but lets not get ahead of ourselves. Building for peak hp has its purposes its just not for everyone because it ignores issues like reliability, gas mileage, budget constraints and especially streetability.

And that is just the thing, some of us dont want to mess with power adders There are LS cars running pretty damn fast (8s iirc?) naturally aspirated.

 

If Intrau can build a 1500 hp stock block with a single turbo, dont you think you could build a 750hp all motor setup with the stock block??????????


If ANYONE builds a street/strip setup for peak hp they are PURELY a dumb ****.

Only 5-10% of ANY builds are built for a peak number, and they are ALL pure race setups.



You are talking about gas mileage and budget restraints in the same breath as a $1500 UNMACHINED block?????????? By the time you got that block ready to assemble it would close to $2000 with NOTHING in it, that would buy the roatating assembly for a stock block.

Talk all that garbage you want, the fact remains you can build 600 reliable HP with the stock block, a number only 5% of LT1 owners will explore.

And if you dont think N20DAVE's setup at 700hp wouldnt get close to the 8's in a 2800lb gutted f body you are mistaken. His car has been 9.90's at 3750 lbs.

 

You continue to miss the point. Gas mileage and budget were merely in addition to streetability which is going to be by far the biggest constraint in most builds. The fact is: People are interested in the cubic inches, not the strength of the block. If you can achieve your goal cheaper/better with the stock block thats super. Your goal isnt universal.

If you want to throw more money at a top end for power thats fine.

If you want to throw more money at a turbo for power thats fine.

If I want to throw more money at more displacement for power im still throwing money somewhere and making more power. Whats the difference?

The only difference I see is that I could use your top end and a turbo kit and make the most power of anything.

750hp stock block... ok whats a 434 ci with the same top end going to make?

Budget constraints - yes absolutely. Show me a street friendly 750hp N/A build. Oh and budget friendly. it woudlnt happen even with this block. Hell, there is a turbo build on the first page of this forum that only hit 700rhwp. Id invest in more displacement over a turbo any day. Thats my own opinion, not everyones. More air = more power. Doesnt matter how you do it and any way you choose will cost money.

If i was talking garbage I would be preaching that the block should have been produced. Im just trying to make you see why this block was on so many wish-lists including my own. If you still think I am an idiot for wanting such a block, then so be it.

 

Have to wonder how many passes they get with straight cylinders. Or, how often they are torn down to check. Run them 'till they break?

 

this is a funny argument. most people that would buy this block weren't looking for records or unreal power. They were looking PURELY at the displacement number.

Hell, I would have wanted it for sure, but I was only going to shoot for 700 max hp. I COULD make that with the stock block yes, but then it wouldn't be with a 427 would it?

Same thing that's already been said; just because you CAN make power with less cubes doesn't mean everybody wants to. Otherwise there wouldn't be big blocks.

looks like there is no need for big blocks any more.time to down size.

 

If you were gonna build a 400 cube engine, would you do it with a big block or a small block???????

Do you need the "I got a big block" speech only to get your *** handed to you by a small block?


I love whipping larger engines than mine, ESPECIALLY 408 inch 15* headed LS engines. Wouldnt quite be the same with a 427 I dont think.

 

Dude, if your small cube small block wasn't so fast, maybe you could stop and READ WHAT PEOPLE ARE TYPING.

 

i like beating down sl1's to......but i want more cubes.ill building a new shortblock soon and i geuss im stuck wiyh a 396.

 

I could give a **** if the new block is canceled. If I want big cubes then I'd much rather go with something like a 455lsx than 50 year old horse **** technology that most everyone, who is wise enough, knows is swirling the toilet bowl of oblivion, and before anyone says "omg the price1111" I don't mean tomorrow, but that kind of **** may be available for the same price that it takes to build a ******* LTx stroker w/in the next few years...

 

I guess people just want to blow money to say "I got a 427"...beyond me I guess, when 1% were gonna put a 340 cfm head on it to make it worth while to build and build some REAL power.

I guess we should all build 396's with stock heads, 220 cam and 1 5/8 headers so we can have "torque".

 

i likes beating down 408 15* ls1's too

 

here is a voice of reason! options/capabilities outside the LTx platform are what killed this block. Not what could be done with the existing block.

I stick with the LT1 for 2 reasons - I like it, and it gives me the advantage of being underestimated in grudge racing. If pure performance was all i was worried about, I wouldve swapped the whole thing out for an LSx before i even stuck a cam in the thing. LS stuff is almost already on par with LT stuff on price point.

 

its been ther for some time now. and in some cases way cheeper to build. and better.

 

I'm impressed because that was a post of drunken proportion.
My last track outing I was accused of having a LS1. Not that my **** is fast, but there are NO LT1's in the area that have anything more than an airfoil.
I too like to take those by surprise. Whenever I used to street race I would never let anyone see under the hood. Same would apply if I had a LS1. It's not a car show!

 

I love opening my hood at the track, first thing they look for is spray....hmm no spray. Next thing you see it dawn on them is.....wtf IS that? LS1-LT1 WTF? When I tell them its a LT1...see the opti? They look at me like DAYUUM...... I love it.

 

Do you have a single plane on that car?

 

this doesn't suprise me in the least bit.

GM set the fate of the LTx engine when they specified it's use to a limited run of select '92-'97 cars. with no compatibility with any other engine offered.

they obviously learned from their mistake with the LSx engine. 95% of all the parts in any LS based engine are directly interchangable with one another.

the fact that the LT1 has become completely obsolete makes me really think twice about rebuilding my LT1, as opposed to swapping in the LQ4 I have in the garage instead.
