What these numbers mean
| Bore/stroke character | 1.179 — oversquare — bore exceeds stroke, which favours higher RPM and larger valves |
|---|
| Mean piston speed at 6,000 RPM | 3,126 ft/min — conservative for a street engine |
|---|
| Rod ratio | 1.508 — short — more side loading and piston dwell at TDC, typical of stroker combinations |

|---|
| Static compression | 9.381:1 — low by modern standards, generally happy on regular pump fuel |
