To calculate the size (or volume) of the engine, we need to compute the volume of a cylinder and then multiply it by the number of cylinders.

### Given:
- **Bore (diameter) \(d = 4.25\) inches**
- **Stroke (height) \(h = 3.76\) inches**
- **Number of cylinders = 8**
- **Use \(\pi \approx 3.14\)**

### Formula:
The volume \(V\) of a single cylinder can be calculated using:
\[
V = \pi \times \left(\frac{d}{2}\right)^2 \times h
\]
Since there are 8 cylinders, the total engine volume will be:
\[
\text{Total Volume} = 8 \times V
\]

### Calculation Steps:
1. **Calculate the radius**: \(r = \frac{d}{2} = \frac{4.25}{2} = 2.125\) inches.
2. **Calculate the volume of one cylinder**:
   \[
   V = 3.14 \times (2.125)^2 \times 3.76
   \]
3. **Square the radius**:
   \[
   (2.125)^2 = 4.515625
   \]
4. **Multiply by \(\pi\) and stroke**:
   \[
   V = 3.14 \times 4.515625 \times 3.76 \approx 53.41 \text{ cubic inches}
   \]
5. **Calculate the total volume for 8 cylinders**:
   \[
   \text{Total Volume} = 8 \times 53.41 \approx 427.28 \text{ cubic inches}
   \]

### Answer:
The size of the engine is approximately **427.28 cubic inches**.
