Re: 1098 rebuild

First, which block do you have? there were two basic 1098 blocks, the 10cc 
and the 10cg.  As I remember, the 10cc was the one to use.  The 10cg could 
not stand anymore than mild tuning.  This was probably related to the bearing 
width.  

Next, why bother with a 1098 anyway?  Get a 1275.

Next, if you must use a 1098, be prepared to spend a lot of money to get no 
more performance than a stock 1275.

I recommend Vizards book for great detailed examples of what works with which 
engine.
