Excellent job guys This! This is an awesome build for street cars and some competition classes. I just watched Steve Morris build the SML billet 2000 plus horsepower LS
monster . Revolutionary for the platform. Chevrolet tho built an excellent motor when they turned this loose on the industry. Keep up the great work 👍
Great video as usual!!
Previous Question removed after you answered. Didn't intend to crap on a great video. thanks Jacob.
Awesome video and beautiful work! I find it interesting that you did use an LS2 or LS7 or any chain buffer. I have never not used one but I always wondered if they were necessary. I like to learn something new, thank you!
We find that they are not needed with a Rollmaster timing set.
Very nice, love it!
Awesome video definitely nice work 😊
Great engine build 👍🏻🇦🇺
Awesome videos, I just found your channel 👍
Very nice engine build
Info on your thrust measuring fixture for the dial indicator ?? TIA
I always wondered why people would wipe off all the lube inserting their camshaft. You just earned much respect.
What's thought on Oil SquirterS Fixture Drilled through Main Oil Galley ? Special for LS7 Panki Gen II Ti Rods Wrist Pins bushing Oiling ~ pulls some Heat off my Mahle coated Pistons ?
extra galley = less volume in the pump = less drag = more power
What would do differently if it were a single turbo setup?
What part number on rockers u use
Didnt show how to torque nuts in vally cover for 6 bolt head ?
Can you write or add the links of all the pets you got for the engine please
I have a 441 stroker with this block on a 5th gen Camaro SS What compression on this engine since it was built for boost mine has 9.7 with an 88 mm precision
what intake manifold studs are those?
Hi there. I’m looking to replace my engine in my 69 Nova. Two questions: What engine would you recommend for a daily driver and secondly could you build it for me. Thank you in advance.
Brand of Grooved Cam Bearing ?
.020" gap for crank sensor to 58 tooth reluctor wheel? Can I get you to confirm that measurement?
Part number of rotating assembly kit?
It’s worth the dart upgrade just to get at those 11 degree heads! I wonder what a N/A version of this motor would make with a street cam in it.
700 n/a on a street set up wouldn't be hard to achieve.
i need that with a 94mm turbo to go
Does any one know if i can just throw on any ls3 crankshaft or are there surtain ones i have to get
With the main caps being already drilled to accept pins, why are the holes in the block filled ? My only criticism is the fact that if you are spending the cash for an aftermarket block, take advantage of all of it's features and safety/strength measures. While splayed caps are far superior to OEM 6-bolt caps, why not pin them for added peace of mind ? Relying exclusively on the lateral block side cap registers without the cap pins seems silly.
I would have expected a ccw crank with a 1000hp+ package
These components won't have any trouble at 1100-1200hp north of that, we would have utilized a CCW crank.
How much would that cool combo short block cost ? I want to do this exsact project ..but I want super charged
Yes how much?
Could you build me a gen3 5.3 to hold 1200wheel
What's the price turn key
when torquing down the rockers what sequence is it done???
Thanks for the Awesome videos!!!!!!
B
I torque/adjust rockers in firing order on every build, find base circle at tdc on cyl #1 and every 90 degree rotation of the crank is the next cylinder in firing order.
What was the reason for marking the bolts with the blue marker?
It’s a procedure we have so everyone in the shop knows that fastener has been final torqued & installed.
Is there anything stoping someone from doing a high compression (11:1+) boosted ls?
There’s tons of people running high compression turbo LS’s. John doc has one right now called Hank. The high compression turbo engines sound so good lol
How much would you charge for that motor after you finished putting it together????
There is a link in the description box
Oil GALLERY.
A GALLEY is an eating facility on a ship
after watching more than a few engine build videos, why is it that no-one mentions what brand of bearing and ring is used?
trade secret?
just curious.
Absolutely not! Honestly with part delay issues we switch bearing brands & ring providers frequently!
Price
How much do you charge for the 1000hp 427 LS dart/smedding engine?
go to thier web sites the have all builds with price
How much does your ls3 427 rotating kit costs?

Fkknn niceee
Can I turn a ls3 in to a 427 stroker?
Yeah all 6.0 ls blocks can be punched out as high as 427cui . but at that point your cylinder walls will be very thin. Good for Na but not for any boost/supercharger or nitrous build. Also with thin cylinder walls comes with heat distortion on the cylinder wall which can worp a block too in high heat environments.... so yeah
@@STEZjorge What do you mean? The cylinder walls are to thin for boost with a ls3 at 427cui? This video is literally a LS3 turned 427 and is TT with over 1000hp... I want to build a TT LSX 376 and stroke & bore it to 427 to replace a LS7 427 Z06 motor (which shouldn't the lsx 427 and the LS7 427 be the same power/505hp? Things i've seen says 600+)
Also I am not seeing the extra cost in stroking/boring it if you were already going to upgrade the rear end, the only extra cost/thing to do would be the boring process itself which is just a couple hours on the machine. So it seems it is only like $1k-$2k MAX extra to stroke and bore the engine which I can't wrap my head around how it can possibly be that cheap, to turn a LS3 6.2l into a 7.0l what am I missing here?
I'm not a hundred % sure but I believe the thinner walls issue is with a stoke ls block he is using a aftermarket dart block which I believe have thicker walls than the stock ls 3
How much would this cost us?
Please contact Smeding Performance for price quotes.
@@buddyjohn Not necessarily. There are to many variables to give a random price out on the internet.
@@buddyjohn I remember my first build
You could’ve made 1000hp with a 4.8/5.3 also for cheaper!
Its called business money generation
It’s more than likely gonna make way more than 1000hp. All depends on how they want it
But you wouldn’t be able to turn it up like that one. Stock ones break at right around 1000 horsepower. He can turn that one up a lot more than 1000 horsepower.
he did
Yes, and you would need more than one block...maybe more than 2 blocks...
Why not say how much to build this……?????
to those who don't know, a stock 4.8 will hit 1000+ hp
For how long Bud cuz I blew mine at 942 wheel in a couple of months you can cheep out all you want till you start asking yourself how many times are you going to rebuild it and what happens when you end up wanting more power your going to pull it out to spend more there's a reason why you go good and bigger from the bigining.
WTH is a "chevie"?
Could of had a Steve Morris.
WHY CHINESE crank and rods in such a nice build?
There is nothing at all wrong with those parts. All shops offer them and all shops use them.
The alternative is a $4k Bryant crank & $2.5k Carrillo rods (if you must have USA parts)
As Shark said, for the application these parts are plenty strong and have amazing tolerances & quality.
@@baby-sharkgto4902 maybe in a stock LS block!
@@JacobVillemain Callies cranks 2000.00 , Lunati cranks 1700.00 , Oliver rods 1400.00 their are many more reasonably options than just a Sonny Bryant crank.
@@racingthemachine3364 I hate to be the one to tell you this…those are all from China
LS3 V8 IS SUPERIOR!!!!! Capable to reach 1000-2000hp with turbos!!!
ENGINE
You can do all that horsepower with the stock block😂 if I buy a race block and forged internals I better be getting more than 1000 horsepower or I'll be pissed😂
Oil “gallery.” Not “galley.”
