[Healeys] 100 engine rebuild

[warthodson at aol.com]

I am preparing for the rebuild of my 100 engine & I need your help with a few questions. My intent is to build a strong/fast street drivable engine. The block will be bored out .020" to 0.30" over & will have a Welch "fast road cam".  I am planning on an aluminum head, steel crank & forged, light weight connecting rods. My first question is should I have the block boiled out & if I do will that require replacing the cam bearings?  I recall reading that they are not currently available. Is that still true?I was planning on a compression ratio in the range of 9.0 to 9.5. I notice that some suppliers only offer 8.6 as their high compression offering. What is the reason for this? Is it standard practice today to use pistons with 3 rings? Where is a good domestic source for pistons?
