If the restaurant job was that bad, that you were willing to become a grease monkey for less than $4 an hour, doesn't that mean you could have found ANYTHING ELSE BETTER THAN MINIMUM WAGE?!? Seriously, nothing in-between? There is no amount of context that would make me not want to question the proper functionality of your brain.

FT-LBS of torque. Not Pound-FT. So old school. Love it!!

Such good, informative videos. REALLY good channel. Thanks Lorenzo!

Great video, I just SUBSCRIBED.

Love the history of the Bash gang!

How much boost

I’m going to see if I can get Lorenzo to build me a engine

That’s some power! Andy Starr! Hey I haven’t seen him since high school! Still that same smile when talking anything motors! I still remember when you blew up my 77 Cutlass! But that’s a LONG LONG time ago! FYI he did figure it out and fixed it too! Oh and Todd’s and Brendan’s eyebrows grew back just fine! Nice build!😅

how did you make the cylinder heads better? what was done by you that others did not do? a lot of people love to say they are better and people come to them for whatever instead of others, but never actually mention why or what makes them valuable. just comes off as blind narcissism

Great stories … very interesting

Enjoyed the video keep them coming

Having over 500 hp in 1970 would be insane.

Amazing work good job ❤

Gorgeous

Beautiful car ❤

Awesome

Cool

At the wheels?

Common on Older heads..

My 4.15 stroke hemi also liked 30 degrees, it also picked up a couple tenths in the quarter by reving to 6500 vs 6000. Why did you guys only pull this one to 5800?

Something is not correct .... That head has enough flow with that camshaft to make 900 to 960 hp NA .... Even if you say 150 drive hp for the supercharger or that its actually making 1100 hp that is only 630 hp NA plus the boost... Its coming up way short of what it should be

Well Always is a First Time so, 🤷‍♂️

I'll take 2. Thanks

If that's all the hp yall made on a 572 blown with a 14:71 blower then you should rethink of how you build motors....that's pathetic!

When running those types of rocker arms on older type Chevrolet aluminum heads, not a good idea, they always pull the rocker arm stud bosses out,or break them off. Run a good conventional rocker arm and put good set of stud girdles problem solved. If you need a offset rocker for clearance on pushrods order them as such for this application.

cool! Thank you

As usual, another solid video 👌

You said 11-71 at 38 secs 🙂

Send the blower in to be serviced, it makes to much noise and not the right amount of boost. My 8-71 makes much more boost than that 14-71 under driven without that loud whistle noise.

DYNO s truly do show what your motor is made of, if you want to be sure find your happy HP spot and run it 10 15 times on the dyno to make sure the motor is solid. Taking a can of NOS and making a crazy number only to blow the motor to pieces when you go to use its just expensive, knowing with settled confidence that your motor is solid makes the label on the engine irrelevant

That blower must be totally de-stripped. I think that engine would love some E-85 and tight stripping, if the valve train could handle it of course.

That rocker system is totally inadequate for blown setup especially on the exhaust side

Pretty weak for 14_71 blower

Like button erergized.

How much of an issue is it to fit the factory intake manifold after decking the block and heads to factory spec? This question keeps me up at night

My brothers speed shop friend used to say, put a set of headers,a msd, and a 850 double pumper and that sucka can’t be beat!

SHOE HORN !!! Lap belt no airbags

I would love to see him compare the LS-6 with a mythical LS-7 crate engine.

Very good info!!

To me, it seems that most engine dyno videos are using SAE Gross Horsepower (Headers, Tuned/Jetted for performance, Spark Advance/Curved for Performance, Open air cleaner, no belt driven accessories). Which to my understanding (maybe I'm wrong) is how the manufacturers rated their engines before 1972. After 1972, regulators forced manufacturers to use SAE NET Horsepower ratings (Pretty much how they were run in the vehicle, from the factory, Full exhaust including factory exhaust manifolds, the tune and spark timing/curve it will have from the factory to meet emission standards, full accessories). Can someone confirm or deny?

That was an enjoyable video. Thanks for the info.

thanks for dyno my favorite cars favorite engine too!

Excellent information with no fluff or BS. Keep up the great videos!

...nice Q&A session. Never thought much about it until I checked deck height on my L78 short block........pistons were down .024

I think alot of people dont understand what u mean when u say "to blueprint a engine". I think they also dont understand alot of engine from all the manufacturers did not have the actual compression in real life as they left the factory then as what they were advertised at & i dont think they understand why that would be.

Good honest info guys. Keep it up. Always appreciated the LS6 454. Like button energized.

What's not to love about a 'Little Red Corvette!' ❤

That’s pretty healthy for a basically stock LS6. Once you get a good intake and exhaust setup those old Chevy factory cam profiles almost always produce the same HP as TQ in various displacement engines too.

The restoration is impeccable. As long as you forget the engine didn’t come with long tube headers and it was painted orange.
