cast crank to use or not to use? I have a sbc cast crank that where the rod journals developed surfase rust while the rods were out of the motor, poloshing didnt help. The crank is already 10/10 and balanced. Would it be ok to go 20 on rods and/or 20/20 and reuse. The combo is as follows 355ci 10:1, dart heads, 256/262 @50 610/630 112lsa crower #000427 solid roller plus a 150-200 shot n2o, 7000rpm.
thanks again

You can go 20/20 but most shops won't. 10/10 is the most we will go, plus bearing selection is still good at 10/10. 20/20 you will not have as many options. Is it enuff rust to where it can not just be polished out?

i tried poloshing it out but it became pitted before I actually discovered it corroded. I have another crank std.std. that just needs polishing that i may be able to use but not sure. I was thinking of weighing the stock pistons and pins, rods and rings, and try to mix and match to achieve a close enough weight. ?.
