I'm sorry. I am a little short on patience right now. I tried searching and after reading a few posts there is too much info to sort through right now. I need to make some decisions over the next few days and I need info.

1. How can I tell if I have Nikasil or Alusil on my 83 SC 3.0? I see there is 10 fins on Alusils and 11 on Nikasils and something about a seam, but it seem to apply to earlier engines. Is there a number or something in the cylinder to tell me what I have?

2. I believe if I have Alusils I'm pretty much looking at new cylinders at the very least (possibly new pistons too), but I think I recall reading that Nikasils can be honed or resleeved? Is this correct?

3. How stupid would it be to buy used ones?

4. Is there any benefit to uping the compression if I have to buy new? Say like. going from 9.5:1 to 9.8:1? Or shoudl I just leave well enough alone?

Thanks for your understanding and any info is much appreciated.
