'38 - '47 Big 4 Con rod length???

Forums

Anyone got a '38 - '47 Big 4 conrod laaying about they could measure and tell me the length eye to eye??

I know there are different length conrods for different models

eg:-

Model 50 -- 6-1/2"

ES2 / Model 18 -- 7"

16H -- 8'

Model 19 --7-1/2"

The Model 19 and Big 4's had similar bore & stroke for the various year periods.

As I noted above, the Big 4 I have is the 1938 - 1947 type and so the bore and stroke is 82 X 120 whereas the later engines were 82 X 113, not to be confused.
