So ive been thinking about a project

[DjLiquid]

Ive got a spare ca18det on the way with a block that's fairly shot and have been doing my reading and instead of boring the engine out im most like just going to find a ca20 block and tinker around with that. Was there a big difference between the CA20E and CA20S (blockwise). I think im gunna start looking around within the next few weeks. During the winter I will try and build a CA21DET (if there's room to bore).
