Hey Jacob.. .. you've grown Smeding so much in the last 4 years. You're really doing some great work. The YT stuff offers transparency to the consumer. Will get with you on our next project. Frank

[@JacobVillemain]

Thank you Frank! Appreciate the support.

[@johnniebarker9746]

Your assembly skills and knowledge r on point u seem to be at your peak with engine building

[@evenmadderdawg]

Came for the lesson on LS assembly, stayed for the smooth, mellow hip-hop soundtrack.

[@KyleGreen-ez1py]

Hell ya Jacob can’t wait to see it when it’s done! Looks like a very trick build. Thanks for the vid

[@martinmdl6879]

Yay! Love the latest tech.

[@mohammedal-maskary8202]

my god, I have been waiting for this content

[@mitchkennedy8686]

Damn Jacob that thing is gonna be a beast I can’t wait to see what it Dyno’s out at

[@SaadF427]

My next 427 bottom End is definitely assembled by Smeding Performance with Jacob's blessings. I'll be in touch Sir. Saad.

[@unclesam7669]

Godspeed guys

[@916chevyboy]

So Blessed!🎉

[@trentdawg2832]

That is one sexy chunk of aluminum ……cant wait to hear her sing!!!!

[@DeltaVTX]

It makes perfect sense.

[@gbass7328]

Great work! Why no mention of the main or rod bearing clearances and that work. Might take too much YT time?

[@tokslut]

I would love to se a build of the 427sbc ;)

[@AC-bl1rl]

Bring the squish!!

[@greymonster8669]

Just curious on why you don’t torque the main studs? I figured you want the to be to a certain spec.

[@bigboreracing356]

He did torque the main studs.

[@greymonster8669]

@bigboreracing365 He torqued the nuts onto the studs, But didn’t torque the studs themselves into the block, he only snugged them up. He actually made a comment about NOT torquing them, I was just curious why.

[@bigboreracing356]

@@greymonster8669 The instructions say to install main studs finger tight. That is why you do not torque them.

[@davidbrown-55]

Love your builds boss. What’s a gd ls head and cam for a street 6.0 ? Thanks

[@stan7764ify]

I wish I could put a LS in my vette!

[@jacevincent2574]

"Small Cam" .692"/.692" lift LMAO Love a good low LSA chop

[@bigboreracing356]

LSA has absolutely nothing to do with chop.

[@brandonbaldassi6381]

Any plans for a 3.622 stroke ccw crank?

[@felixortega21]

I have an aluminum 5.3 I want to resleeve and make a 427 out of do yall have anything for it

[@mikefoley7561]

I seen another builder that on the main studs and head studs he’ll run them all the way down and then back them out about one full turn.What do you think about that?

[@JacobVillemain]

I use to do that. Not sure if it makes a difference

[@gregHames-u6n]

Are you going to match the highest torque with the next gear so when you change gears you will be at the engines highest torque?

[@JacobVillemain]

Thats a great idea! We will log and compare average power & torque numbers

[@paullutherborrow637]

It’s IWIS chain The best chain you can get for timing sets They come standard on the premium Rollmaster timing sets

[@JacobVillemain]

The Katech C5.R IWIS chain is 100% different than the standard Rollmaster IWIS chain.

[@bigboreracing356]

Daido, RK, and Tsubaki chains are better.

[@shortymack340]

I wonder what happened to the other engine that supposed to have been so special that he built fr the vette hmm

[@JacobVillemain]

I sold it! Its now in a Foxbody

[@martinmdl6879]

Can you build an L87 for my Suburban that will not blow up?

[@aphil4581]

How big could that block go to...CID? What's your piston to head clearance? Gasket? thickness?

[@davebays4238]

You don't set the thrust bearing on these?

[@JacobVillemain]

I do -- big hammer

[@terryspray2319]

Make sure the heads are redone!!!!

[@JacobVillemain]

Stock heads are not going on this engine lol

[@craigbreto9600]

The iwis chains I think are made in Germany they are good chains

[@bigboreracing356]

The Chains with larger pins are better.

[@seanbennett5633]

I ordered the 1300hp ls rotating Assembly from Smeding Performance about two months ago or so. The 300m rods were not and option at the time. How much more power would that same 1300hp kit be good for on nitrous if I went with 300m rods? I haven’t even opened up the boxes yet

[@bigboreracing356]

You should run aluminum rods when making over 1300hp with nitrous.

[@seanbennett5633]

@ I will only be around 1000whp or so on a 400 shot. Do you think I should be in the safe zone? I do use progressive and it’s a t56 6 speed C6 vette.

[@CLEEPER1]

Thats hydraulic roller?

[@JacobVillemain]

Yes it is.

[@ricardoquezada3109]

I have to measure my push rod length on my ls7 I just had rebuilt tomorrow but I had the heads re surfaced and block .003-.004 I did not check ptvc and i can’t spin the motor over I realized since I can’t access the bolt I did mark cam lobes I think are on base circle as well but I am using short travel Johnson link bars how cooked am I

[@ricardoquezada3109]

I have prc heads and new mhale pistons with relief cuts as well don’t know if it helps

[@SNELLERIZED]

Volume is WAY too low.

[@bigboreracing356]

Standard volume pump is sufficient for this application

[@StephenWindmeier]

You omitted checking the rod and bearing clearances and what values you were shooting for and why. Disappointed.

[@JacobVillemain]

I have made several videos showing me checking main & rod bearing clearance. I don't want to bore viewers by showing the same thing in every video. I also don't usually say what I am running because every keyboard warrior knows better! This combo will run .0025 on the mains & .0023 on the rods.

[@bigboreracing356]

Nothing to be disappointed about. Bearing clearance is not rocket science.

[@TheRoguelement]

Hey can I just say .. What a grand & Trendy fella you are that you would while still moist behind the ears opt to own the Z06 vette and I can only wish you all the very best of luck pal . The Bone yards are filled with Boys thinking with the wrong head did the same thing only to learn they hadn't been on the planet long enough to acquired the necessary skills needed to keep such a car between the lines and as iff that wasn't enough your going ten better and installing a whole other time zone in speed .& H.P. . Don't start out drag racing in the lower Super stock classes Or do the Skip barber deal and learn how to actually swing these cars around ..and judging by the condition of your complexion you can't be that far out of Boyhood ...Why not go get laid a lot of times build a beater you can do endless burn outs with and when your a bit older and your aggitts have dropped completely and your voice changes maybe then go by a good used Vette to learn on .. But hey WTF do I know I've only seen this done a few dozen times in my life but hey .. go ahead don't take my advice my dumb shit younger brother didn't either and he learned it all the hardest way possible with personal injury ... Anyway good luck ..hey listen when the car gets away from you the first time try to fight off the desire to saw away back & forth on the wheel it just makes irt worse

[@390nm]

Typed all that and still said a whole lot of nothing. Impressive

[@bobvoeh66]

I guess you didn't watch his videos of his previous Vette where he was doing the Standing Texas Mile?

[@bigboreracing356]

Dude is a washed up wanna be that is jealous that a young man is making more out of life than his old washed up behind ever did😆🤣😆
