<VV> 140 power increase

[Bryan Blackwell]

Bob's list is very close to what I was thinking as well.  Given the 
budget of $2000 - $2500, you're really not going to get much past a 
high quality rebuild - there just isn't enough volume in the market for 
a Corvair equivalent of the small block crate engines.  However, a good 
rebuild with the noted mods will result in a very nice engine.  I'd 
probably consider using a slightly hotter cam than the 95 cam 
(something around 260 degrees advertised), since the 140 typically 
likes to rev higher than 5k.  I'd think of 3500 - 5500 as the sweet 
spot in the rev range for a nice street 140.  You may wish to look over 
some of the pages on my web site for more info, and you should also 
consider picking up a couple of the available books out there.
