I used this site a decade or so ago and no longer have access to that account, but that's not why I'm here. I recently got an 84 D50 4x4 2.6l and the engine blew up (head gasket, then vapor locked the engine on one of the cylinders and likely damaged a rod). I read a long time ago about the 4g64 engine being a wide block, but i have been having trouble finding the info again on it.

whats the deal with the 7 bolt vs 6 bolt crank shaft? and what if anything would prevent the use of a 7 bolt engine in place of the 2.6? starter location or maybe pilot bushing? are the later 2000 model eclipse and the like engines the same (other than the obvious being that they are fwd orientation)

I can post this elsewhere and I will continue to sift through the site info here, but if someone could direct me to a resource, I'd appreciate it.

I know, not exactly the right place to start asking questions, but I know someone will chime in to help direct me.

thanks
Dustin
