Breathing new life into the 318 in the Scamp!

I'm beginning to think that the KB pistons with some blend work on the heart shape end is going to do what I want it to do.

I have a feeling that the cc is higher than 62cc anticipated, because the valves are tapered face rather than flat.

I think a piece of plexiglass, some grease and colored fluid is going to give me my answer. If the cc is somewhere near 64 and I can stay below 9.5:1, I can snake by with some nice blend work.

If I do blend, I'm gonna have to cc everything, but I'm beginning to think that keeping the quench up in the head, rather than down low is going to be better in the long run. I'm thinking 65cc finished is the magic number I'm looking for with these pistons and if I do some blending to open up cc, it will help deshroud.
@65cc, it puts everything at 9.23:1 on those KBs.
