Is there any place I can get the dimensions of a 66 engine?  I have a OC-4 with a 4 cylinder that now has a new hole for putting oil in the pan(threw a rod).  Been looking for a different engine but there aren't any at the moment.   So I figured a 66 engine might not be to far off as a replacement for now.   Bad thing is the engine blew up in the first to minutes of get it started for the first time since I have owned it.  Lots of playing around only to have it die.
