One down and two to go.

How do I calculate the bore/stroke ratio and the rod/stroke ratio?

What is the rod length of the 235 truck engine for 1956?

Bore divided by stroke is the ratio your looking for:

BORE: ÷ STROKE: = RATIO:
3.560" ÷ 3.9375" = .904


ROD LENGTH: ÷ STROKE: = RATIO:
6.812" ÷ 3.9375" = 1.73

We cannot solve our problems today using the same thinking we used when we created them!
