Amazing work ethic and cleanliness. Ppl take notice! Would love to see this motor in a vid on the road and the owners response to it. Do you video long block builds too?
You forgot to mention to split your main and rod bearing oil clearance number in half, because you are checking the inner diameter, not the clearance between the surfaces. I learned this on our Chevy 230 i6.
Great video as usual! My question is, will this build with the added compression and increased cam lift & duration still run pump gas? What octane will be happy do you think? Thanks.
Always wondered how they knew the clearances would grow exactly so many tho when it is running and hot. Guess they have a little bot with a little Mike in there that does that.
Wait so you can run aftermarket connecting rods with an OEM forged LS/7 crankshaft without doing anything to the rod journals ???? Just rebalance the crank is all ??
DUDE! I wanted to see the pickup and pan assembly of this wild power plant. Come on!?!? LS7 with a GM PERF DRY SUMP! I appreciate you showing what you did. I like your channel and the builds. Don’t skip the details on these special projects, dude! You knucklehead!
That's a pretty similar cam spec as I'm running (253/267 .665/.665 116+6). But I built my "LS7" to 502ci. That's a lot of cam for 7 liters. When the customer gets annoyed by the giant gap between 4th and 5th because the motor won't cruise under 2K RPM, the close ratio ZR-1 transmission will take care of that. You can get a built 6060 with 3.90 gears for the low low prices of only $16K from RPM transmission. (ask me how I know). Now to to go find the video of how it dyno'd and drove...
Hey guys , I have a question, would y’all want to work on a 6.5 turbo diesel ? For a refresh . I know y’all do gas engines , but would u want to go into the 90’s diesel world ????
Curious where you got the new block from? I want to put an ls7 in my truck but I’ve been looking for just a new block and can’t find one anywhere all local dealers said they don’t have them and can’t get them which I’m not sure is true
What’s the RPM redline on this motor, the new pistons are lighter than stock? But the stock rods weren’t sufficient or needed to be replaced? Love the enclosed dry sump, and what’s the power goal?
Engine should easily make 650whp New redline probably 8,200. However the long runner manifold the customer will be running will limit it to 7,400 before running out of air. With a larger plenum/shorter runner manifold the engine could easily turn 8,000 & make big power
is the term at TDC "quench" or "squish" for compressed volume? I knew a high performance jetski engine builder that called it the "squish" volume. Which is correct? Both?
@@stephennummie7631 It takes 850-900rwhp to run 8.99 in a full weight c6 z06 if its converted to a th400 or powerglide. I dont think there is a single c6 z06 reliably in the 8s for many runs with the 6 speed manual on corvetteforum.
You can save the block ,you just do not know how. And you are reusing the crank,and did it wrong,good luck it running lone time ,and you lost 50 hp without starting.
I appreciate seeing you turn it over after every pair of pistons go in
It’s surprising how many people just spin far enough to install the next set
why? do u think its just a good habit to build?
Forced induction is cool but man N/A is so intriguing
Just like NASCAR…
Lol I always say that, any one can add boost and be fast, but to do it n/a you a bad builder/driver
I've owned a number of force-induction cars; turbo and supercharged.. and nothing (IMO) is near as much fun as a high HP N/A build.
@@zaknefain1001000whp from a boosted LS is way more fun than any N/A combo

Love to see the power this engine puts out on a engine dyno
Great video! I'm excited about next week's build!
do the steel rods make the LS7 feel any lazier compared to the Ti rods?
I see a lot of clearance checking, which is great. But they all were perfect. What do you do if they are not?
Tag the customer car ….. I wanna see the dyno vids … nice work
Very enjoyable.

Great job. Love the shop. You should consider getting a sunnen dial bore gage and setting fixture. Lots of money, but worth it!
We have one for our cylinder hone!
I have a mallet cars built 427 with an a&a vortech 6lbs boost. 750rwhp on a 93 tune.
I’d like to see a video of the car running this motor. My LS7 is stock compression but cam specs are pretty similar.
Great video as usual!

Thanks.
It will run 100% E85
@@JacobVillemain thanks for your reply :)
Good work 👍
I would love to see the dyno numbers on this engine!
I’ll have them hopefully by end of this month. Gotta get that break in done once the car gets put back together next week
@@dominickguerrero5664 what did this build end up making???
@@703z06 686 still stock head casting. Looking to upgrade soon. Should make a little over 7 here soon
Great video!
Thank you!
Why wouldn't you use the OEM Ti rods?
Yea i was wondering why the heavy h beams if its na…
Always wondered how they knew the clearances would grow exactly so many tho when it is running and hot.
Guess they have a little bot with a little Mike in there that does that.
Lol, I like this comment
Aftermarket casting heads would be better imo but hey i think it will still outperform above all expectations
8000 rpm with that hydraulic cam? Wow!
Liked, subscribed, awesome video.
I emailed you guys for a build quote and was told LS7 blocks are no longer available so it would have to be a dart block.

hey man, I’m considering becoming a small motor tech / mechanic. Would you recommend it or have any advice? And what is the money like?
This will be a healthy motor for sure. Wonder why he didn't opt for an ATI balancer?

It’s OEM, you can look it up
How do you prime the oil system prior to starting the engine.
Curious as to why you were marking the bolts with a blue marker on the timing chain? What is that for?

Would you recommend doing anything to stock ls7 engine block, when gettin the head issue addressed ?

On the main caps do all the arrows face front of the block?
All your N/A builds get 13.1 compression? I’m guessing with the big cam overlap you can run pump gas.
Curious where you got the new block from? I want to put an ls7 in my truck but I’ve been looking for just a new block and can’t find one anywhere all local dealers said they don’t have them and can’t get them which I’m not sure is true

Deck height should be measured with or without rings?
Where did you buy a new LS7 Chevy Gen IV block? As far as I know, Chevy performance no longer sells the LS7 427 production block.

Hey Jacob, at what power level do you recommend going with ARP main studs?
1,000
A little modded and it would be great for my 01 Silverado to replace my getting old LM7.
How much HP can it put out being NA
is the term at TDC "quench" or "squish" for compressed volume? I knew a high performance jetski engine builder that called it the "squish" volume. Which is correct? Both?
Same same
Squish is technically only the small part between the piston and head that‘s not connected to the combustion chamber volume
I need that in my C5 Z
Me too tbh
Curious, is that the recommend torque sequence? Seemed awfully non-standard to me. ???
I do not believe in torque sequences for main caps that are not connected.
Still waiting to see a 4.6 Mod Motor build
No heads?
Omg why is the crank laying on the table like that!!! When I was an apprentice if I did that it was a wrench to the face
What is your opinion on taking the lS7 to 440CI? Looking to get as much power as possible NA and still drive on the street.
I am a big fan of running a 4.125” stroke in the LS7 block.
@@JacobVillemain Nice I keep hearing both sides of the debate. I knot its only 13 CI but if you have to tear the engine apart anyways why not
I've heard that the SDPC spec'd 4.100 Callies crank offers better oil control over the 4.125" stroke....
@@milojanis4901 one of those things where if you ask 3 builders what you should do, you’ll get 5 answers.

So what happed when they chose to run boost😢.The always say no power adders until they add them😂
What oil pan was that
OEM LS7 oil pan out of a Z06 Corvette. Grand Sport corvettes would also have the same pan.
Why do use valve timing at .05 ?!?!?!?!? Use .006 timing or duration its easier tells us more about camshaft !!!!!!!!!
