I have a GM forging #2690 (67-85 350) with .020 under large journal mains and std. small journal rods. Crank was storked to 3.562. It was mag'd and polished 12-15-08. The journal sizes and strokes are as follows:
Mains / Rods / Stroke
1= 2.4283 1/2= 1.9989 1/2= 3.563
2= 2.4283 3/4= 1.9987 3/4= 3.562
3= 2.4284 5/6= 1.9984 5/6= 3.563
4= 2.4283 7/8= 1.9985 7/8= 3.562
5= 2.4281
Crank has factory balance holes in the counter weights and was never re-balanced.
