I have a crank that I got w/ the last car I bought. It has been counterweighted. I was wondering how I can identify the stroke and the jounal size?

How about measuring them? OK, measuring the stroke requires a little bit of thought, but the journal sizes? Just measure!
For the stroke: Set the crank flat on a table. Put a straight-edge parallel to the crank--measure the distance to the two "near" rod journals and make sure those two numbers are the same. Then measure the distance to the near side of the "far" throws, and re-check the measurement to the near side of the "near" throws. The difference (far - near) in millimeters is the stroke. --DD |

Looks like a stock 2 liter 71mm stroke. Stock 2 liter journals but you have to measure the journals to see if they have been ground. Or if it has been ground they usually stamp the size on the crank. But the best way is to measure it

That looks like a 2.0L rod. 1.7s and 1.8s have a balancing pad on the small end.

typical to see a .010-.010 crank when they have been welded up
Measure the journals. a loc al machine shop would probably measure it for free if you dont have the mic |

Give us the part number of the rod bearings. 2 litre RBs start with "039", 1.7/1.8 start with "021". The Cap'n
