You inspired me to try :)http://www.thingiverse.com/thing:1131508
Still a lil bit tweaking before it's ready for printing since I'm not that experienced with Solidworks yet and all the measurements were taken with non-digital caliper so some of them are bit off, for example I know I screwed up things like the camshaft lobe angles, which needs to be redone when I figure out how to get more reliable measurements hehe :p
And as for now, I cannot model the block itself seeing taking dimensions while it's attached to my car would be kinda difficult.
