What oil viscosity for a 383 stroker engine?

For a 383 stroker engine, a common oil viscosity recommendation is 10W-30, especially for moderate climates and typical driving conditions. In hotter environments or for high-performance applications, a 10W-40 or even 20W-50 may be appropriate to ensure proper lubrication under increased temperatures and stress. Always consult the engine builder's specifications and consider factors like ambient temperature and usage when selecting oil viscosity.
