[FC] unusual block?? ID help?

[N2VZD at aol.com]

i have a block i just took apart for the block only. it had 145 cu in guts  
in it , early 80hp stuff.  it is a TO606V in very small type.  it  looks 
factory , except it had been rebuilt with a 010 crank etc. it had  mismatched years 
of low hp heads. the thing that has me puzzled is the block  itself. it had 
early crank etc , but is factory cut for long stroke. the casting  has the extra 
oil fill hole tapped out and plugged with a pipe plug..looks  factory?  i 
know a lot were cast like this , but never saw one drilled  before. also the left 
side lower flange has drilled , threaded holes on the  lower flange , like 
where the 60 choke ring thermostat mounted??  looks  factory also.
if i send someone who is a good historian of this type , can they explain  it 
to us?
i hate to use it , but i am about to load it with new parts for a 110ish  
engine for FC use.
the only other one i have is in someone else's van and is a old engine i  
will have to hog out for the 164 cu in stuff.
i have several detail pictures to share.  maybe i can get them put on  our 
website ( _http://www.cnycorvair.com/CNYCorvair.php_ 
(http://www.cnycorvair.com/CNYCorvair.php)  )   somehow soon.
