Hello All,  
Does anyboby know of documentation  on doing a REAR engine V8 conversion? 

 
 
The old adage applies. You can put anything anywhere, if you have enough  
money. There are two main problems with conversions into the Corvair. First  
is weight distribution. The Corvair motor was about as much weight as you 
would  like to have hanging out back for a normal car. Almost all rear or Mid  
conversions have the option of front mounting the cooling system and 
battery.  That helps the front rear distribution issue, but the less weight out 
there, the  better. That is why the BOP/Rover Aluminum V8 motor was popular, 
although  several Iron-blocks have been hung out over the years. Want to 
impress your  friends with wheelies?  The other main problem is the direction of 
rotation  of the Corvair motor. To install any motor in the tail, and use a 
standard  rotation Corvair transaxle, you will have to run the motor 
"backwards". There  are several other motors, over the years, that ran the 
direction of the Corvair.  None of them were high performance models. Some specific 
motors were converted  for Marine use, where, on larger inboards, a pair of 
motors drove two,  counter-rotating propellers in the water, which made the 
ships go straight.  Chevy V8 motors - Way before the LS1 - and V6's and 
probably others.  Those early Chevy motors, with rare exceptions, had iron 
blocks and were  pretty heavy. GM didn't have the casting techniques they have 
now, and weight  wasn't such a priority.  
 
I have a long term goal of putting one of Chevy's aluminum V6 motors into  
the back of a Corvair. with 262 cu in, there should be enough power, and not 
 much more weight than a BOP V8. I have almost everything I need . Now, If 
I  could find an exhaust crossover set-up from a GM Syclone, the turbo 
version  would probably be "interesting"!

 
The aluminum  BOP converted cars do come on the market once in a while. 
Keep your eyes  open!
