I'm curious what happened to the block that was obviously sleeved? Just guessing that it may have had casting flaws that the sleeves attempted to patch?
Not being negative, just that this stuff is potentially history being written. Perhaps one day that prototype block will sell for big money at auction.
Pretty sure I'm on record around here somewhere as being in favor of the flame spray.
That is a good question. I know there has been more than one cylinder head cast as we noticed the Elio logo had managed to rotate between a set of photos. It is very possible there has also been more than one block cast over the last year as thing have progressed as well.
Hopefully in the future we will get to understand a lot more of the interesting little details which happen behind scenes during a project like this.
