"No replacement for displacement" is what I've always been told.

Waaaaaaaaaay too many people have their imagination all wrong. The crankshaft is the heart of an engine. The more stroke and force on that stroke... the more power. Torque is what wins races. A smaller engine/smaller stroke has to wind higher to reach the level of Torque and power that the bigger engine already has from the start.

BBC for the win! I am a die hard big block guy mainly because of my age being almost 50 and grew up with BBC muscle cars, boats, and trucks. The biggest trend on boat racing is still BBC...as usual. LS engines are the daily driver standard GM came up with to survive the EPA gas and oil regulation issues about MPH. I have never owned an LS in any of my 20 plus hot rods over last 25 years (and still own 7 of them) but considered it for sure after MSD and Holley made it possible to put a carb on one around 2012. You are a guru Rich for sure and my BBC favoritism is shared by every top fuel dragster, super gas drag boat, and all SS GM 58-74 muscle cars. Trucks fortunately have a BBC option until 2013 which spanned 55 years(2009 was offical official announcement of last year made but loyal guys preordered 3 years worth of more to be made). GM's final BBC ZZ632 BBC makes 1,000 HP and 850TQ without power adders under 6,000 RPM. Never heard of an LS that did that! Thanks for your never ending sharing of the hard work you do to find real world answers! 👍

Yeah the LS might be the "better" more modern engine, but I will stick to my 454 with an Edelbrock carb on top and SM465 4 speed behind it. We have several trucks around here, and the only one that will outpull the 81 with the 454 is the 74 GMC with a 455 Olds swapped into it. And the best part...I can work on the damn thing with basic hand tools out in the barn, instead of having to take it to the shop where I have computer access to diagnose it

Pontiac V8 guy myself. 454 Big Block Chevy just needs a stouter camshaft profile and not much more. Wipe LS for torque and Hp. All LS Has Dinky Crankshaft Thrust Bearings the #1 weak area and impossible to improve any. An Engineering Flaw they all have. Big Block Chevy Has a Large crankshaft thrust bearing. Pontiac 455 has an even larger crankshaft thrust. Important when putting continous Heavy loads on a V8 Towing or Racing. Will not fail hard use and abuse 454 BBC or Pontiac 455. Worked on Grain Trucks with 427 Tall Deck BBC and pulled 80,000 lbs loaded no sweat. Worked on Firetrucks with a 454 BBC Tall Deck with water tanks built in pumper tankers weighed 100,000 lbs. 454 BBC Pulled effortlessly. No failures any BBC.

Your not likely to ever see the mileage of a 454 get close to an LS, that’s Richards argument when he says “better” the ls design is so much more efficient. In the same way, your never going to see that low down torque production in the LS, pretty much for the same reason, the port flow on the modern engines is so good, you don’t see high velocity at low rpm like you do on the older designed bbc heads. Small ports with big cubes creates very high velocity at low rpm, that’s why “peanut port” truck heads make so much low rpm grunt and run out of steam above 4000rpm. All those cubes and the old inefficient heads need lots of fuel and air to run. The new stuff is so much better, but small cubes and big ports can’t create the grunt down low, it needs the rpm to get the flow velocity up.

Sill at idle to 2000rpm not a lot of turbos going to make up ft-lbs versus displacement because the turbo won't be working much yet. Would take a very small turbo with some big gates to get the low end up without being a huge restriction later on.

Gotta love that big block 6mpg flooring it or put putin.

Great comparison Richard, I love these kind of comparisons. It would be a cool experiment to see if one added a small turbo, very small, on these STOCK ls engines to see if it could raise the low rpm velocity and therefore low end torque production, like they do on the modern small 3 and 4 cylinders. Something with less then 10 lbs boost for towing. The mpg issue will always be a problem for any tow engine. Your not likely to ever see the mileage of a 454 get close to an LS, that’s Richards argument when he says “better” the ls design is so much more efficient. In the same way, your never going to see that low down torque production in the LS, pretty much for the same reason, the port flow on the modern engines is so good, you don’t see high velocity at low rpm like you do on the older designed bbc heads.

All those cubes and the old inefficient heads need lots of fuel and air to run.

Would like to see low rpm torque results from a peanut port stroker 454 compared to std oval port.

I don’t understand why anyone would even think a standard ls would come close to what the big block offers in Torque-I guess growing up w/big blocks gives me the advantage of knowing from experience-they do cost a lot more to build tho

Not GM, but still trucky. I've towed with a manual trans 300 powered Ford, an auto 351 and an auto 460. All EFI. Those 300s are sleepers for sure. It would run rings around the 351 towing. The big block....well, it's a 460. It could tow its own gas station. And probably should.

300 vs 351 in your comparison was the trans fault. 300 was a good engine but not a better tower than the 351 if both equally equipped transmissions

@@EGGINFOOLS But how often do you see a 351/M5OD 1/2 ton running around? The 351 is a great truck small block for sure, especially with the long runner efi intakes but the 300 was effortless. I've pulled anywhere from 2000-6500lbs with a a 460/E4OD with a 33" tire and 3.55s and it did a decent show of itself. It's no racer but it does make 400ft-lbs pretty much everywhere.

Blessed be those with strokers

I'd love to see how the new 6.6 L8T compares

a 402 or 408 or 416 with an aloominium block and aloominium heads is light weight. It'll fit in a Nash Metropolitan too. With a factory intake and a factory Vette pan, you could mount it low and probably still close the hood. You might not tow with a Nash Metropolitan, but you could. And you'd be cool.

Honestly not bad for what it is. Top end power isn't the greatest but it has a tractor-like torque curve that I like, doesn't slow down or come out of OD on hills. My favorite part about it is how dry it is underneath with almost 300K on the clock. Never leaks a drop of anything.

I’ve got one ask... can you keep the same graph line color for each engine? Would make it a little easier to track each engine if it had the same color line on each graph

I love big NA cubes for low-end torque, but in my car I can only fit a 9.240 deck. Not crazy about core-shift and improper valve angles. 🤷‍♂️

I would like to see the power numbers averaged out under the curve. My guess is that in stock trim the 6.0 produces very comparable average power and does so more efficiently.

One point of clarification -- The 6.0 LS engine did not replace the big block. The Duramax did. GM went into the 2000's with three basic engine choices in the 2500 trucks. The 6.0 LS, the 8.1 Big Block, and the Duramax. The 6.0 was never intended to compete with the two bigger choices. It was used in a similar way to the SBC in the older trucks; generally sold for non-towing applications, but is still capable of towing when needed on occasion. If you wanted a truck for towing, you chose the 8.1 or the Duramax. The customers overwhelmingly chose the Duramax, so the 8.1 Big Block was dropped. The 6.0 didn't factor into this.

6.0L, HD 1500, 2500 AND 3500, TOW PACKAGES AND 4WD-IT IS USED FOR TOWING

About 20 years ago I ran tow trucks for a AAA contractor as a side gig & one of the trucks had that exact 454 setup in a '98 3500HD & 5-speed. Talk about a total dog! Absolutely nothing below 2500 rpm & always felt like you had an extra 2 tons in tow. Same shop also had an early '87 V30 with the TBI 454 & 4-sp. That truck would pull like a tractor down to 1200 rpm but as expected, dogged out pretty quick on top. I always preferred the older truck tho, torque is where it's at when you're doing work. The older truck would KILL the newer truck in mileage too, granted we're talking ridiculous single digit 8 mpg vs 5 mpg but still, you could run hard an entire day in the old truck & still have 1/4 tank left but the newer 3500? You'd be looking to fill up before the night was out. I was never that impressed with the 454 Vortec setup & it was geared with 4:88s vs 4:10s. The LS engines are racing motors but honestly, not particularly suitable for hard towing. I'll put my flame suit on but seriously, the torque curve says it all.

I also have a 6.0 nv4500/4.10s 2500hd and my tbi murders it working too. my 454 is a 4l80 truck and also has 4.10s. when I threw it on the shop dyno the 454 started making more torque at 1400rpm than the 6.0 peaked 😂 ( when I threw them on the dyno the 454 was slightly modded. )
