LT1 vs SBC What’s the Difference?

Автокөліктер мен көлік құралдары

I get asked this question a lot and many people say it’s the same as a typical Small Block Chevy ( SBC ). The correct answer is Yes and No. So, for this video, I answer that question. What’s the difference?

    I got tired of giving history lessons on the SBC motor line on how the LT1 is different from the rest of the SBC's. So I made this video. I have an LT1 and an SBC but I sure won't call my LT1 an SBC no matter what you say. Enjoy Like and subscribe... Or call me a fool I don't care. Cheers 🍻🍻

    You know it's truly mind boggling when so many so called "EXPERTS" don't even know half of what you described in the video. Good job of "splainin" the not so subtle differences between a 90's LT-1 and a SBC. Like you I have owned both (I still have my 70 Vette 350 with the Aluminum Heads that was a special order only package I believe in the 70 SS Chevelle don't quote me on that I could be wrong, I know where mine came from because my wife and I cut it from a wrecked Corvette in a Salvage Yard in Nebraska and the odometer on the Vette read just over 1400 miles and when we tore down the Engine to inspect it it looked just like new inside...the original factory crosshatch in the Cylinders and the lack of Carbon deposits on the Piston tops and Combustion Chambers of the GM Aluminum Heads was all we needed to see.) We did pull the pan and inspect every rod and main bearing set but they also showed really no wear at all so we put all new gaskets and swapped out the factory cam and lifters for a much better one and we just this last summer put 75,000 miles on the Engine since we put it in our Street/Strip 72 Rally Nova that we restored to it's good as new condition a couple of years ago. The only difference in it is the drive train....the engine of course, and the M-22 close ratio original Muncie Rock Crusher with face plated gear set that comes complete with the 2nd generation of the original Mr.Gasket in line Vertical Gate Shifter, a twin disc clutch, Blow proof Steel bell housing, After market Custom Drive Shaft, And complete Moser built 12 bolt GM rear Differential with 4:10 gears and we re did the back half for a full frame job and wheel Tubs to accommodate the Micky Thompson rear tires and wheels....it's a pro street car that runs legit 9.50s in the 1/4 mile on one shot of juice....we can spray 2 shots but that puts us into the 8.90 class and that's just too much for a little old street car that still is a real honest street car.

    The LT1 Generation 1 92-97 is a 350ci small block. The LT1 used a reverse-flow cooling system which cooled the cylinder heads first, maintaining lower combustion chamber temperatures and allowing the engine to run at a higher compression than its immediate predecessors. Never the less is a SBC

    It's a SBC in the sense that it's a small-block and it's a Chevy engine.. so you are technically correct. (the best kind of correct). But it's also like saying your Silverado has part time "all wheel drive." As in, you can put it in a mode where all the wheels are driven wheels. It's like... Well, _yes,_ but there's a way to make that much less ambiguous with a little colloquialism...

    @@nthgth Big difference IMO. Your silverado is 4 wheel drive with selectable rear wheel drive. LT1 and SBC use the same heads (if drilled for reverse or standard flow cooling), same crank, rods, pistons, oil pan, valve train, ....intake can work on either. Same bolt pattern for the headers/exhaust manifolds. Really the only differences are: Reverse cooling. The LT1 does not have the boss on the block for a mechanical fuel pump, though I don't think other late small blocks like the L98 or Vortech had it either. Those are the only real differences. Everything else can be swapped interchangeable between them, but you can't always mix and match, ie you can't mix LT1 and gen 1 SBC accessories.

    So, I worked in Summit Racing website department for years. I promise you that using Summit Racing’s website to justify your point is a very bad mistake. Categorizing or titling a party solely depends on who’s entering the part. There is so much human error it’s not funny. Also when some of these categories or attributes were created it was much easier to call it SBC and LT1. The correct way should be like how they are doing the LS motors now and calling them LS Gen 1, 2 and so on. Not to mention there are newer LT1 engines.

    They were always categorized by generation. The original SBC is a GEN 0. After 1986ish, they are GEN I. The 92-27 LT1s, as was briefly mentioned in this video are GEN II. However "vortec" engines that were made into the 2000s are still GEN I engines. The LS1 and related engines, GEN III. There area GEN IV series of LS engines as well. The current "LT" based engines are GEN V. Its really not that difficult. The big kicker is, they are ALL SMALL BLOCK CHEVY engines lol.

I've always loved the LT1 engine, especially because they get no recognition anymore due to being overshadowed by the LS series engines. Thanks for showing that. I think GM knew enthusiasts would convert these engines to a carbureted version and see the opti-spark was a problem.

If it was the same it wouldn't be a different generation though. The gen 2 SBC is an evolution of the gen 1 SBC and the proof is that the two have a lot of interchangeable parts or parts that can be adapted to work on the other gen. And you can't go by a Summit search description because it's set up for the average person who barely knows what kind of car they have.

    If you changed five Optispark's on your LT1 then you wasted your money. Optispark's are dead nuts reliable and typically last well over 300,000 miles. Try checking your negative ground connection or replacing your spark plug wires next time.

    LT1 is just another evolution of the small Chevy. Just like the 87 an earlier had different intake bolt pattern. And different rear main seal. Just like the 67 era 327 has a crank case vent tube on back of the block next to distributor going into carb. Just like the 327 had a large main journal version that was available in the trucks. Just like the 55 283 had NO OIL FiLTER, and again had a different crank case vent tube that went along behind block and pointed and vented right on to the ground. The small block Chevy add various design changes throughout the years. LT1 was just another change

    BEST ANSWER OF ALL BRIAN! It is just another evolution of the SBC. I bet many guys don’t realize that a stock 1986 up 305 crank is the closest in weight to an stock LT1 gen 2 sbc. Now what are totally different animals are the LS series up and are no way small block chevys. Completely different family tree.

    LT1 is simply a RPO code. Would you call the L69 305HO a L69 not a small block chevy? It has differences from previous years, such as an aluminum intake. What about the L31 350? It has a completely different head design, which is based on the 90s LT1, but has standard cooling. However, you can't simply bolt a conventional SBC intake to it. By your reasoning, chevy hasn't built a small block since the 1950s. The design has constantly changed ever since then.

    Very good description! But you missed all the pieces I was interested in. :( Can you elaborate on the exhaust manifold ports/orientation between the two as well as cranks / block mating surfaces for bell housings? I'm specifically asking because I'd like to swap an older 78 350 SBC for something like an LT1 block. But it's going in a boat so I need the stern drive parts to still mate up and the exhaust manifolds to fit the same SBC patterns or I'm "dead in the water". If some of the later blocks are also compatible, I might even select one of those too. Your feedback is welcome.

    I've owned a '96 Z28 over 20 years(and still do), so I've got plenty of experience with the old Gen 2 LT1. It's design is based off of a SBC and some parts are interchangeable. However, there are enough differences as to why you should not consider the Gen 2 LT1 as a SBC in the classic sense. Speaking more genetically from '55 til now '20, many people refer to the Gen 1, 2, 3, and 4 motors as SBC. I understand why folks do this, but it's like trying to argue that a ZR1 and a Yugo are the same thing as they are both cars. Well yes, but we all know differently.

    So to counter your argument on the summit search, if you are filtering by engine, select chevy then look at the listings. Your big blocks V6's all show in groups and low and behold Gen I through Gen V SBC engines. Gen I is everything V8 with a small block trans bolt pattern up to 1997 excluding the LT1(92-97). Gen II is the LT1 (92-97). Gen III and IV are the LS platform. This leaves Ger V the 2014- current LT platform. Also for interchangeable parts, there are fewer specialty parts then there are shared parts. Just about all internal components from a one piece rear main seal SBC ( TPI and Vortec) are interchangeable. This includes the rotating assembly, oiling system, cam and valve train and as you showed you can even put the distributor in the back with a little engineering. In short the LT was a way for the consumer to test new ideas for chevy while remaining a small block.

    The production of this video is really good. So I agree with "how the LT1 is different" statement you make however I got interested in what GM thinks or at least thought..... Opened my GM Performance Parts Catalog from 2000. Under the Chevy Small-Block V8 section there are numerous parts listed for the LT platform. They did not designate or claim the LT platform was not a Small Block motor. Nevertheless, I think your video did a great job in demonstrating the differences GM implemented to improve the platform. Maybe you should do a video on the Big Block Chevy evolution from the 348 to the 8.1?
