  • LT-1 V8 (non-supercharged or supercharged)

Despite being based on the humble Chevrolet Camaro, TAW decided to skip the milder, lower-powered 6-cylinder from its 70/SS lineup and just go with the 450-horsepower LT-1. It’s the most docile option available in 2024 and is definitely aimed at enthusiasts who want the style and performance of a restomod musclecar without going too far. For context, this entry-level model puts out almost enough power to match the power of the new Ford Dark Horse Mustang, which, by the way, is the most powerful naturally aspirated Mustang ever produced.

In addition to the larger engine capacity, the biggest difference here from the base model is that there is no naturally aspirated option.

This top choice on the food chain sends the 70/SS into overdrive with two different power outputs. The least powerful version has 1000 horsepower, which corresponds to the power of the Bugatti Veyron. Yes, if that wasn’t crazy enough, TAW will sell a 1,500 horsepower package, and it’s still totally road legal. According to engine bay nameplate we spotted in this Instagram postthis 1,500-horsepower powerplant variant also produces more than 1,300 lb-ft of torque, giving the 70/SS more torque than the F-350 Super Duty.

The main differences between each Chevelle 70/SS engine variant

Key differences

  • Output power
  • Price
  • desire
  • Cars with higher performance have additional advantages

There are similarities between all the engine choices, such as the fact that they are all high-powered V8s, but there are also some differences that stand out. For example, in addition to the obvious increase in power, the type of supercharging is different in different variants. Additionally, if spec’d with more powerful powerplants like the 1,500 horsepower 454, TAW also upgrades major brake and suspension components.

The 2024 70/SS starts at $175,000, and while pricing for each trim on this reimagined Chevy Chevelle isn’t known, we’re guessing that’s because they’re custom-built, so prices will vary widely depending on how each car finished, it stands to reason that the more powerful machines will be slightly more expensive than the base LT-1 models. This is another key difference between the engine options available.
