Another advantage of the LM7 engine is the extensive aftermarket support surrounding it. Everything from performance cam kits to boosted setups can be easily applied to the LM7 engine, making it incredibly flexible for enthusiasts who want to customize their build. With the right tuning, the LM7 engine can produce impressive horsepower levels, rivaling much more expensive engines on the market.
