Frequently Asked Questions
What is the best roller cam for a 383 stroker street build?
For a street-driven 383 stroker, we recommend a hydraulic roller cam with duration around 218-230 degrees at .050 and lift around .490-.520. The Comp Cams Xtreme Energy 12-423-8 or Howards Cams 110245-12 offer a good balance of power and drivability. Choose based on your converter and gear ratio.
Can I use a stock torque converter with a 383 stroker cam?
It depends on the cam profile. Milder cams like the Summit SUM-8700R1 or Edelbrock 2106 work well with a stock converter. More aggressive cams with duration over 224 degrees typically require a stall converter (2000-3000 rpm) to perform optimally. Check the cam’s operating range.
Do I need to upgrade valve springs with a new roller cam?
Many aftermarket cams recommend upgraded valve springs to prevent valve float at high rpm. For cams with lift over .500 inches or aggressive ramps, we strongly advise installing new springs. Cams with lift under .490 inches may work with stock springs, but verify with manufacturer specs.
What is the difference between hydraulic roller and mechanical roller cams for a 383?
Hydraulic roller cams are quieter, require less maintenance, and are better for street use. Mechanical roller cams offer higher rpm potential and more power but need regular lash adjustments and are less streetable. For most street/strip 383 builds, a hydraulic roller is the practical choice.
Will a roller cam improve fuel economy on a 383 stroker?
Generally, a performance cam will reduce fuel economy due to increased airflow and overlap. However, a mild roller cam with early intake closing can maintain or slightly improve economy if driven conservatively. Most owners see a slight decrease in MPG with aftermarket cams.
