394" (396) Engine built by Dustin Lee Racing Engines (DLRE)
Lancaster CA, Heads & Intake by Tony Mamo (MMS),
Cam Specced by Kip @ Cam Motion, LLSR,
Daily Engineering Dry Sump.
Dustin breaks in all his engines on a Dyno with a carb.
Engine was run on the Dyno of Bill Maropulos
3 X National NHRA Comp Eliminator Champion.

Engine made 727 FlyWheel Horsepower @ 7200 RPM, 700 @ 6400

583 lb ft @ 6000 RPM, 548 or more from 5500-6900 RPM

15.2 inches of vacuum @ 7200 RPM from Dry Sump (no vacuum pump)
BSFC #s ranged from .33-.38

I am absolutely THRILLED with the results!
It exceeded everyones targets involved with this Project.

Details to follow.

Well done!

Everything about this combination is awesome. Thanks for sharing.

PS. Love the 1.76 rod ratio on this thing. And those LS3 heads on a 4.175" bore must have a phenomenal coefficient of discharge. There is just so much right about this.

CAMMOTION PERF

Hell of a build! Another 700+ HP Cam Motion LLR. How about a picture of this beast?

Thanks David, i have learned a lot on this forum from many members
over the years.

Thanks for your help Kip! i have an I phone shot I took at the dyno that i will
try to post later today.

1.84 hp per cubic inch at just over 7000 rpm. I'm impressed to say the least. This thing will fly with the right chassis setup. Is the car manual or auto?

I love the big bore/short stroke combo. You did an excellent job and I salute you, sir.

Very nice results. With the FAST mid-runners, you probably won't change the curve or the peaks much from the Victor Jr.

Nice numbers. Can you post a graph?

Thank You! engine will go into my 99 C5 M6 being built for the (1&1/2 Mile)
Mohave Magnum, Goal 201 MPH NA, need at least 550 RWHP under ideal
conditions, shooting for close to 600 + 35-45 more from Ram Air @ 100 MPH+.

jhshnh

I think you'll hit those goals. Good luck and tell us how you do.

KCS,
Thanks,
Dyno is old school SF 901 prior to graph software.
i have phone shot of Dyno #s which I will try to post.
Dustin (builder) sent photo by text and i am technically challenged
to post it, LOL, but will figure it out hopefully with some help from
my wife when she gets home.

A 430" ERL short block with Texas Speed LS7 Heads 11.75:1 Comp. &
hydraulic cam made 682 FWHP @ 6900 RPM &
600 lb ft @ 4900 RPM the next day with the same builder, same dyno, &
similar conditions.
for what its worth.

Debating internally wether to spend more money to dyno @
WestTech to get Fast #s with Mid Length runners, probably
~$1200ish, agree with Jake, curve will be similar with a
little more torque from 3500-5500 and would get to pull
7500+ RPM, didn't get a chance at Bills Dyno as fuel was
low (VP101 100 Octane Unleaded) and didn't want to take
a chance running out mid pull.

Thanks man. I need to get back at it. Car is off losing a little more weight right now

Very well thought out build there sir

Killer build!!

Tony @ Mamo Motorsports

Dan, Guys

Just wanted to pop in here quickly to say a BIG congrats on the results of this build

A few people mentioned "well thought out etc"......that is an understatement to the extent you would never know unless you really knew Dan

The amount of thought (and second thought) Dan has invested in this build could have powered the eastern seaboard for an hour in the event there was a power failure!! Dan and I have had more conversations than I can count related to this build over the 2.5 to 3 years it has taken Dan to get here and I was just one of the resources (and a friend) Dan confided and relied on over all this time.

I was happy to be involved and have been dying to see what my ported Mamo Motorsports 260 LS3 heads could do on a naturally aspirated engine (helped a few dozen CTSV guys with boosted combos make big power!). I would be hardpressed to find a better N/A example of their potential than this build and they delivered as much as I/we could have hoped for with the relatively modest cam timing in this engine (SR cams always look bigger on paper than they really are). The torque output and the way the engine carried power is awesome and certainly other factors contributed to that but most of the sharp guys know the foundation of any really good build starts with the cylinder heads.

The ported FAST with the mid-length runners I helped Dan with.....personally I think that will boost TQ output even more and carry just as flat....I think its arguably an even sexier power curve with the plastic fantastic on there due to the straight shot runners, all of which are equal length (compared to the hooked uneven length runners in the single plane design). The wild card is the single plane typically works like most shorter runner intake designs (losing torque for gains in peak power), but its really a mix of different runner lengths and very different than the more optimal (IMO) straight shot of the FAST design (discussing the mid-length runner version specifically here).

Anyway....I'm pretty confident torque is up and power is similar.....but I wouldn't be surprised to see this combo pick up everywhere with the new induction. Unfortunately I don't think we will get a true back to back to ever really know because this has to be done on the same dyno and I know from talking to Dan about the logistics of that happening its going to be tough.

So once again....major props to Dan and a big congratulations. Im really happy for him and as I mentioned earlier glad to have been a part of it. In fact I had a thought while typing this post and it's something along the lines that Dan's results isn't unlike the lesson(s) we learn in life over and over again (some guys need more lessons than others....LOL).....you get from it what you put into it and Dan sweated every detail of this build for years (not months!)....the end results were clearly earned and well deserved and none of it was much of an accident!



Cheers,
Tony

Seriously a nice motor you built there Sir!

You just put a pile of 408's to shame with this monster.
