Conn Rod, no piston design.
Race motor.
If the rod is long enough to allow the piston to miss the crankshaft, you have the right rod.
I am more concerned with the correct piston than rod.
Is there enough top ring land?
Is the dome/top thick enough?
Is there enough 1-2 ring spacing?
Can I keep the oil ring out of the piston pin hole?
Is the pin located correctly to allow rod to dome clearance?
Does the piston have a fully support skirt?
These come to mind before I think about a Connecting Rod.
