The .7 HEMI engine has gained a reputation for its power and performance. When it comes to upgrading the camshaft, enthusiasts often look to options that can maximize horsepower gains. Two popular choices in the market are Comp Cams and BTR (BluePrint Racing) camshafts. This article will compare these two options, focusing on their ability to achieve 480-520 horsepower gains.
Understanding Camshaft Upgrades
A camshaft upgrade can significantly impact an engine’s performance by altering the timing and duration of valve openings. This change can lead to increased airflow, improved combustion, and ultimately more power. For .7 HEMI engines, selecting the right camshaft is crucial for achieving desired horsepower levels.
