So, I figured out what killed the snot rocket in Blytheville. I dropped a valve. Grr. In addition to the pistons and head both being destroyed, it gouged a couple of cylinder bores pretty bad. I was already overbored .5mm, and going further means custom pistons, plus weaker walls.
I may just find another block and build it, but I am wondering about sleeving this one. Darton sleeves look to run ~$600. Is there a better option? Any chance of DIY'ing these? I have access to normal knee mills, but not engine block specific machines. Looks like it's anywhere from $1000 - $1500 installed price. At that price, I'll probably just build another block. At $600 + DIY, I might just sleeve this one.
