Tearing into my motor and wanted to get some opinions. 77 930 case with 83 SC pistons and heads (best i can tell from looking at it). All head studs are dilivar and 3 uppers broken. Hence the engine is out.
1st question: These look like ARP rod bolts or something else?
Cylinders have 10 fins. I can't really seem to see the hash marks on the walls unless i look below the ring travel areas. Does the 10 fin count ensure these are Alusil?
Does this look like something i can just reuse or do i need to do some work to them? Can you hone Alusil or no? I have seen conflicting stories here and i'm not sure what i should do.
Last question, is there a way to determine what crankshaft i might have? or are there even many differences besides the direction the dizzy turns and the number of flywheel bolts?
I'm only able to work on this a couple hours a week so its slow going but i'll try to get a better look at the rest of the cylinders and pistons soon. Just wanted to get an opinion from someone that has seen the insides of these motors before.
