It's quite possible but I'm not entirely convinced either.

 

Smokey I dont think it's as easy to get 800 as you say, I have good sps ported ls3 heads at 12.1/1 compression and a 246/262@.050 llsr. 689/.672 112+4 cam specs and a sniper intake.
. I didnt have a vacuum pump at the time of engine dyno not feel the operator brought the engine up to operating temp as he made all pulls at only 120 deg Fahrenheit coolant temp.
. My engine made peak tq of 575@5200 rpm and peak hp of 671@7700rpm.

. Chassis dyno has a vacuum pump and through a 5500 stall and 4l80 transmission, 12 bolt with 4.10 gear it made 553rwhp. True I can run a lot more cam but this thing already revs to the moon and drives like a very mild ls1.
runs 10.30 at 132 mph at 3900 race weight, so it's not a slouch either. Honestly getting caught up on dyno numbers can Get you broke. Get it to run the number on the track and that's what matters.
if not into the track then get it to pull hard in the application you are using it for.

 

Good combo.

 

Ain't Skeered...sorry but your wrong....most follow or looking @ the Wrong names for hp....on This Site.
This is with Rules. Can't afford or 2 do a high dollar build with hopes of....Got some who make hp in their sleep with less. 4.185 stroke was the hardest part...from ER.

 

Reason I LOVE.... ER Racing: He's not trying to Sell me Anything, but gives me knowledge and experience from working with the Ls platform as well as others....Guy's a porter & builder on not just 1 platform...with 2 REC championships...Looking to take down Andrew with SAM this yrs LSX EMC winner..know both. You don't ask a guy who makes 750 with 440+ci how to get to 800.

 

It is. His car Rips for what it is. Not fully optimized yet either.

 

I used some good names and my own people I trusted. Car runs strong and drives great so im not disappointed at all. But when you go around telling people they failed because they didnt hit a certain horsepower, and 800 is normal expectancy all you are doing is making them feel like they done it wrong. Not true at all, if I just dropped 500 lbs I'd be well off in the 9s ,heck im going to be dead bottom 10s with just a couple more tweaks at 3900 lbs. Nothing to sneeze at there so unless you want a dedicated race car and are ok with dropping a whole lot of money, anything over 600 hp is a ripper. 500 plus at rear wheels with an automatic is going to be a blast

 

Nothing is as easy as Smokey posts except for reading about other peoples setups and posting how easy it is to make big power because you read it on the internet. Waiting for him to actually put up and build something himself instead of posting about motors he has had nothing to do with but read about. Don't think that will actually happen anytime soon so I'll just continue to read his posts as the comedy they are.

 

If my guys are doing it and the other names are not...who's fault is that and what does it say.

.Ain't Skeered ..look @ your name? If you wanted x amount should have gotten with a builder who's done what your thinking....Erik@HPR? You've got a great build that your happy with..Cool!

But BS is BS and 800 isn't asking 2 much.. Maybe for some builders. Who you No has more to do with maken proven known hp and or being fast. Guy's should have a expectation of what they'd get with cam + compression + bore x stroke. Higher expectations requires different thinking.
Rule 1 Fill the cylinder with more =
so what i've read,asked,looked @ is all fairy tale...this is not a dream. Everyone has a goal and what's desired ... If u believe 800 is some hard thing with a 4.125+ bore your crazy or ......dude did it with a 6.0 block below 7500. Funny....bigger and better requires less on Cam, Compression which was below 12.0 more like 11.5 .... again funny....everyone has different expectations....

 

Don't hate the truth .....with less size & a 4500.... plastic Lovers...fill the cylinder

 

In4results instead of just referencing others builds...

 

Smokey B, happy holidays bro, but here is analogy im comfy with. The majority of what you post as referenced is an anomaly of sorts. Its not the norm, they are on the very high end of expectations for whatever reason. If it was the norm or so easy, than the secret would be out instantaneously! These guys would be hogging up ALL the business and kicking Boeing out of their warehouse cuz they need the floor space. In this hobby, EVERYTHING is give and take compromise. I tried to politely prove that to you other day when you named 6 builds I personally know nothing about. But the one I was aware of turned out to be 15:1 compression on Ethanol, HUGE fawkin stall, racecar shyt! Not saying it didn't make the number, of course it did. Yes, I want his numbers too. Heck, prolly gunna surpass them. But I don't have ethanol here, I hate carberuartors bcuz its 2020 n efi is life! But that car would not be the choice for X% of guys here. Darth is in the pursuit of hp, is ringn out all that he can, with a combo he s picked and comfy with based on past experiances of his own, because he doesn't wanna cut up his cowl or buy 6 different intakes to test against 6 different cams...etc etc...Not everyone knows what you know or willing to accept what you call reliable, fun to drive, etc. I AM NOT stupid, I just don't know everything bout motors like you do. That doesn't make my first attempt at 700+ hp bs.


P.S. Im an HVAC guy. Im a good one too. Id run circles around you bcuz you simply don't know it. But I wouldn't shyt on your furnace that gives you heat and ac. Its what you know and accept. Heres one for ya bro that's technical_ Im heating my 3000sqft house with 110*-140* water temps and just under 60,000 total btu s, often less. Im using only 3tons of air to achieve the same comfort in 98* temps. Lotta technical stuff and details I left out, but its defly not the norm and wont work for every one of my customers. Hell it doesn't even fit rule of thumb or even anyones napkin math.

 

Merry Christmas everyone.

 

Merry Christmas 2 U & Every 1 also brother....Enjoy!

Both well over 30k builds by the time you turn the key. Pretty cool links tho for sure. If money comes that easy, than i guess 800hp is easy. Than you need a credit union to fund a 98octane fuel bill to go out to dinner. Im thinkn most guys here are lucky if 20k budget is allowed.
Race fuel, dry sump, packaging constraints, and huge upfront costs=NOT SO EASY, IMHO

If im droppn 30k on a build, i ll take a turnkey whippled 427ci and 900+ whp to show for it.
Im gunna email Lingenfelter and ask some questions SMOKEY style. I like that set up.
Happy holidays to everyone...hopn Santa brings Bortous alil luck n progress on his motor

 

Was just going to say some of you need boost in your life. A whippled 427 would be downright hateful.

 

my 427 would wake up with a better intake like the high ram but if I'm going to cut my cowl to clear one,it would get a whipple. My short block is set up with looser ring gaps for boost later on.

 

For the price of a hi ram and supporting stuff you could add a turbo. I did the same thing with my LS6, built it NA.....but kept the rings looser "just in case".....then it happened LOL.

 

.026-.028 1st and 2nd ring gaps. I can put a good bit to it 😁
