What size comp cam can you put in a stock 350?

In a stock 350 engine, a common choice for a Comp Cams camshaft would be in the range of 260-280 degrees of duration at 0.050" lift. A popular option is the Comp Cams Xtreme Energy series, which offers improved performance without sacrificing drivability. It's essential to ensure that the chosen cam works well with the stock components, particularly the intake, exhaust, and torque converter, to maintain balance and reliability. Always consider your specific application and intended use for optimal results.
