I’m so glad I found out you have a channel from your comment on muscle rods channel. Love engine building.

[@charlesclemons741]

My new favorite engine building channel! Do you degree your camshafts or is that not necessary?

[@JamesStover-gr3hw]

Jacob, It would be nice if you went over the overboring of the 6.0L to 4.070. The to look out for. What thickness of the cylinder walls are you hoping for being N/A. I would assume boost would be out of the question. What is the max bore for boost? 4.030? Thanks

[@PunKtuRed_Jazz]

dude im going to be watching this series for a bit, just comp locked my L76, sooo balls to the wall now, gunna build it to not die again with boost

Thanks for the information looking to put one in a Cadillac CTS any suggestions for me

[@lambchopLSX87]

What do you recommend the max overbore on a 6.0 block? Lookin to do a stroker on a healthy shot (350+) possibly boost at some point, and haven’t messed with more then stock bore stuff up till now in the ls platform

[@phild6509]

Any experience with using edelbrock pro flo xt ls3 intake in a N/A application?

[@MrTurtleboy80]

What pistons did you use? I'm looking to do a 12:1 ls3 using the factory crank with a 6.125 rod. I'm having trouble a with piston selection. Suggestions are appreciated.

[@champspec]

I’m curious why you measure the clearances with a bore gauge w/o the crank installed? I’ve always torqued the caps with the crank installed. Then used pasti to measure the clearances. I’ve never been able to get as accurate of a reading with a bore gauge for oil clearances. Also make sure to check the pump cover clearance if re-installing a pump.(i assume your’s was new). Also surprised you checked OOTH clearance w/o torquing down the rods on the crank. It’d surely change some. But ballpark for gasket thickness is all you’re looking for anyway... more than one way to skin a cat. It’s good to see a builder that actually has a clue about proper engine assembly. I cringe at most of the others. Keep up the good work!

[@smithjohn3080]

Agreed, it's a time saver that can eat your ass later... also not really a prefect TDC if the rod isn't tq'd to the crank with proper bearing clearance 🤔 Otherwise this yougin seems to be ahead of the curve

[@mathewshackelford8037]

If you only use plastigauge, you won't know the actual size of the hole relative to the O.D. of the corresponding crank journal.

[@junesmotorworx]

lol... You gotta kidding me.

[@jimstover6747]

I haven't watched the whole video just yet, but have you gone over what the min. wall thickness should be when attempting to bore a Gen IV 6.0L iron block to 4.065" /LS3 Specs? What would the max. bore size if one was going to put a LSA SC on it ? Will it change if you stroke it too? 4.0" thanks

[@mickhirk4734]

did you use a rod bearing on the rod when checking deck height?

[@dustinsamson4879]

Why do you torque from one side of the to the other? I thought you go in sequence starting from the middle work outward. I really aint sure thats why im asking! New to this stuff but from what few videos ive watched thats what everyone says to do.

[@farhanfarooqi7190]

Is boring a 6.0 65-70 over fine or do u have to sonic check each cylinders? I really want to do this but the couple shops I went to all are saying no just do 30 over that's it. All said I'm crazy trying to do 65-70 over.

[@803brando]

you ever drill & pin the front timing cover?

[@jonathanmoore5112]

What kind of clearance do you like on a ls2 block on boost?

[@BowtieClusters]

Are the cylinder walls too thin for boost or nitrous on a build like this?

[@parrot69777]

Any worries of cylinder wall thickness by boring that far on a stock cast block? I have seen guys say it's ok, next guy says it should be sonic tested first, next guy says they cracked all the cylinders after doing this........

What brand tool are you using to check clearance?

[@Airman..]

I've heard the sleeve jacket in this cast iron block is pretty thin, is that true ?

[@grantbassford33]

Really enjoying all of the content your putting out, keep it up. From your extensive experience building engines, if you wanted to buy a 5.3 LS where would you go? This could be rebuild crate engine, used with all accessories attached or other? I look forward to your future videos.

[@small-torque]

OK. This is a pity. I would have been very interested! Can you please tell me which cylinder heads (?ported/cleanout?) and camshaft you have installed? Do you have some dyno data from the engine? I would estimate it at 700ps and 700lb-ft. Good job man and thanks in advance!

[@TOMVUTHEPIMP]

If the bearing is too loose, why are you going to smaller bearings???

[@shawnrenaud3395]

I am so glad I stumbled on to your channel!!!! You have incredible content and it is crazy that you do not have at least a million subs! Quick question, I just put together my first LM4 aluminum 5.3L short block and I bought a nice billet true roller timing set and installed it. It went on fine but there is almost no play what so ever in the chain. You said in this video the aluminum block will expand so will that cause an issue in my timing set putting strain on my new cam shaft if there is little to no slack? There is tons of info about timing chains being too loose with LS online but I can not find anything about it being to tight. I know you are a busy man but any info would be greatly appreciated.

[@samuelwarren8737]

Everything I see says you can't bore a 6.0l to 4.065 because the cylinder walls would be too thin did you have to sleeve the block??

[@ls87gbody]

Naturally aspirated it most likely would be fine. You would still want to sonic check the bores just because of the differences in castings. On a boosted setup you would want to only bore it if you needed to clean up the bores. The more meat the better in that case because it helps keeps the cylinders round when under pressure and heat.

[@Dreadz530]

they just recommend not to do it because there are the ones that fail. so no one is going to risk their rep saying yes its fine to do it to every engine and then when it fuckes up the same dudes are coming back crying saying that you said this would be fine and blah blah so its just easier and safer to say its not recommended to do it. just like certain parts can easily exceed 500 horsepower but they still recommend that setup as good for 500 pounds. Its like the older 4.6 mustang motors they recommend not going over 500 because of the pistons yet you get on a forum and theres plenty of people pushing well past it but then theres also people who went 15 horses over and busted so when you have situations like that its best to just say its not good over 500 pounds. sure some or many go exceeded but thats the level where you start to get into how well the block was taken care of and all these other factors that arent going to be the same across all the blocks. same with t56 trannys they are recommended to what 5-600 horsepower yet theres guys out there powershifting them with 1000whp and beat them daily and have over 6 months of daily driving and weekend racing but tremec or other companies that sell them arent going to market them being 1000whp becuase thats not standard and when your in business you dont want to be making false claims and having people come back and threatening to sue and just all the other headache plus depending on where you live they could actually have a legit case against you and you could then be liable for all the damage that happened if the car was in that power range you said it was able to run in and it broke so its always better to undershoot and have something as critical as the engine end up being over built instead of running on the upper power limits and having more maintenance as parts dont live as long

[@Dreadz530]

@@ls87gbody yup and honestly if your running boost the power gain from the bore wouldnt even be that noticeable or be that much of an approvement when you can just run stock bore or slightly freshened up and just ran a couple more pounds of boost to get the power gain that you would see from the engine bore not to mention turning up the boost would save a lot more money since you arent pulling the block and then taking it apart or paying someone to do it then machine it and then you have to buy fatter pistons now so thats another cost then you gotta reassemble it and install the motor when you could have changed a spring or hooked up a computer and put a few more pounds of boost in and achieved more power and costed you less money and way less time for the same result, well actually it wouldnt be the same because then you still would retain the thickness of the bores so you would have a safer engine by turning the boost up vs boring. if your that determined to get some more cubes just throw a 4" stroker in the 6.0 and have 408CI (boring and stroking only gives you a 416 anyways so the bored job is only gaining you a minimal 8 cubic inches. i would say that is far from worth the time and the money if you were wanting a higher powered motored by for this instance and only wanting to stay around 600 there arent issues and arent seeing the same pressure in the engine as you would with forced induction
