SBC two bolt main block, reasonable race power limits

Dragsinger · 11-01-2008, 08:23 PM

To have a reasonable answer for my question, allow me to explain this SBC will be properly assembled and tuned. Also, it will not be abused by overheating nor run with denotation.

The application is a, dedicated, trailered, IHRA Crate Motor car making about 450 - 475 horse with an upper RPM limit of about 7100 RPM. [auto trans]

Are any SBC engines racing at that power level with two bolt mains and giving satisfactory service life?
