Boost is great, but I love seeing how much power you can get out of a normally aspirated engine. The LS7 is still one of my all time favorite GM engines. Nice to see a big cube NA Gen V engine! I would have loved to get a good listen at the start up and idle, though.
AMG uses robotics and power tools on their special "hand built" engines but also computers to measure out tolerances and even the smallest details. I trust it more than a shop that does without the tech
Lol the stingray or grandsport is a 376 compared to a stroker engine 427. Anyone who knows anything knows that a boosted car needs more power to beat a n/a car with similar power. Roots chargers run out of power at redline or just before and n/a engine is lighter = adds weight over the front axle80-100 pounds not including the weight from chiller killers , meth setups etc that you will need to keep the iat temps down so more like 150lbs or more added to front of car =undesirable no heat soak, more reliable and consistent (can be hot lapped and do it over and over again and run laps hard with out having timing pulled or going in limp mode, plus they pull hard up top and have a very strong linear predicable powerband which is key for auto cross and road course racing and still fun on the street for bracket racing. Give me a 700 hp n/a engine over a 750 supercharged engine any day of the week. You can do drag, auto cross and road course and kick ass at all band if someone wants to race for money you can always throw a 100-200 shot of nitrous on to of the high compression n//a that the bottle can easily be removed when you track your car that will kill any boosted car.
you just talked me out of a C7Z06....I don't want a blower motor....I LOVE the LS7. I want NA 427 in a C7 and this is the answer.....BRILLIANT. This should have been an option at the dealer like the callaways.

There is no way that car is fun to daily drive. With 700 N/A, I imagine it's gotta have a pretty nasty cam that would make city driving no so fun. I could be wrong though.
jalloor Too expensive, too time consuming, too difficult to reproduce effectively and efficiently, and 700 naturally aspirated hp won't pass emissions... Like it or not, but these cars are mass produced, it's the only way they'll make a profit from them... Why bother pushing for 700+ na hp when they can get those same numbers by installing a small and cheap blower rather than wasting all that time and money porting, re-sleeving, fine tuning etc, the power output will be the same, but it'll take significantly less time, money and effort using a blower than going na...
I own a 2017 Chevy SS Sedan with the stock LS3. I've been on the fence as to which upgrade to choose. If I were to follow the primrose path by others, I would have a new block cam-ed, ported with internals, coupled to an SC, and tuned as a daily. Conversely, I just can't shake my desire for an NA alternative. This video inspired me with the cleanliness of their shop and how they approached the build with surgical detail.
Always up to you man id be interested to hear what youve done since your comment. Ive had turbos and SC in the past and for me unless your sending it down the track or have a heavy wallet its not worth it. I have got an LS2 VE SS with 490rwhp which is enough for the street, reliable maintainable power with the N/A nostalgia.
I am in love, i will get a grand sport and send it to yall pair perfect with my c6 z06 I would like it with a big cam, ported heads and lots of NA power. You guy are really professional i am serious i will get in contact
I'm a die hard GM and N/A fan, and seeing 100hp/L out of a 427 is always cool. I know you guys stopped making Corvette race engines after GMPP brought everything in house in 2010. However, I hope that your work with Pratt & Miller still created a strong bond. I have several questions, the last of which is more of the blurred line between race and road engineering. 1) When it comes to the Gen V LT1, how long do you think it will take the aftermarket to come up with a true tall-deck block with direct injection that will support 100hp/L and 500ci? The LSR-TDRC2X block from Concept Performance has been hailed as the next big step for making reliable power for the LS platform - and it supports up to 505ci SAFELY. Obviously with the LSR block reliability is key, and it supports 505 ci (4.180"x4.600") safely before the wall thickness is no longer sustainable. But it's still an LS-based block, without direct injection. Also, the tall-deck version only weighs 120lbs, which is kind of crazy. A tall-deck production LT1 (LT7?) block that weighs 120 pounds would be sheer insanity. 2) Going back to the LS architecture, an engine builder (who shall remain unnamed) using what looked like a Dart block, old-school intake, made nearly 870 hp/740 lb-ft out of a 'conventional' 502ci (4.165"x4.600") build - and it was meant for a STREET DRIVEN car. They posted the dyno run on RUclips only a few weeks ago, and it looks entirely legit. What kind of cam and compression ratio would support such a ridiculous amount of torque AND power, even with a huge stroke like this? 3) Everybody talks about drivetrain loss and the different ways to calculate it. You lost about 76hp from a 700hp build, so I'm gonna round it and call it 10% loss total. Most people land somewhere between 8 and 15 percent - but obviously it's different for every engine, transmission, and drivetrain package. Which transmission did you get that loss with, auto or manual? And if it was the manual, how much more or less power and torque would you see at the wheels with an auto (or vice versa)? 4) Lets say we take the aforementioned 502ci crazy engine, and we drop it into a car running a CF driveshaft and a 9" rear with 3.00 gears. What would be the difference in horsepower and torque at the wheel with a traditional manual (say a beefed up T56 Super Magnum) versus a 6-speed paddle-shifted sequential box, like something from Albins, Holinger, HGT Precision, or the like? And would it be practical (not necessarily comfortable, but practical) to run a sequential on the street assuming that its torque capacity exceeds 1,000lb-ft? I've heard that the HGT boxes are the quietest and have barely any gear whine - plus they're EXTREMELY light.
@@fabbas01 I feel it. But I. Challenging us car guys to keep the manual alive. For all those folks who say it's faster.. We'll that's great and all but I enjoy driving and connecting with the vehicle. I respect if u don't mind an auto. But picture this. U have a dude in this C7 NA CORVETTE manual. Vs someone in a Tesla P1000s. And ur gonna do a dig race. Well who's the real winner. The guy who actually has to drive the car to win or the guy who simply presses Ludacris mode, the brake and Gas together to the floor, and lifts the brake pedal? Perfect example of where we're headed
Funny you should mention it. We've seen less than desirable oil pressure in dry sump LT applications, so we came up with our own oil pump that we just released. store.katechengines.com/high-capacity-scavenge-high-capacity-pressure-lt-dry-sump-oil-pump-p812.aspx
that 7 litre sound makes me erect, whereas the 6.2 litre sounds like an old man trying to reclaim his youth. 427 with cam is probably the best sounding v8 of all time, in my opinion anyway, but keep in mind I own an MKIV supra so my opinion is wild and I don't like backpressure.
We have since built a more aggressive version. Still 427, but more aggressive camshaft, our new LTK heads, better intake manifold and E85. It made 806hp.
I'm curious how this 427 compares to a stock LS7 and a LS7 at similar power levels as far as low rpm smoothness and drivability are concerned? I'm guessing the VVT and DI help @@KatechPerformance
@@lorddoobsworth144 the LT1 427 platform will make very similar power to the LS7 with the same supporting mods. We can make right at 600RWHP with both very reliably. The LT1 will have a bit better drivability.
the comments asking how to get that 'sound' for their stock LT1 cracks me up. Yes...just a cam and exhaust. buddy. That'll do it, lol. And maybe another $20,000

It all looks beautiful I was wondering if after all the working of putting everything back together perfectly to the best of ur ability does the engines have problems where you’d have to pull it all apart to fix stuff or if it’s done right it should last a long time with this much horsepower?
When building an engine like this, don’t you have to run it for like 200 miles with break in oil or so to create cylinder and piston wear patterns before all out dyno-ing?
