<VV> Ultra Numbers (crankcase availability)

[BobHelt at aol.com]

To expand slightly on Jim's report below, Corvair crankcases were available  
from the Dealers in several configurations.
 
First were the bare crankcases, for both 140/145 and 164 cid.
 
Then there were available crankcases for both cids with a non-turbo  
crankshaft and a low-hp camshaft already installed. You had to install a high-hp  cam 
for the higher horsepower requirements. Turbos were left to replace both  
crank and cam (or use the bare case).
 
Lastly there were the replacement engines that came without many items such  
as clutch, distributor, carbs, spark plugs, sheet metal, etc. These were  
configured for specific displacement and hp apps but were considered "universal"  
since they could be used for both MT and PG use. (that's why the clutch, carbs 
 and distr were missing).
 
Regards,
Bob Helt

You are  confusing universal replacement blocks with replacement short  
blocks.  Universal replacement blocks are just the block halves with  
studs and nothing else.  They have no stampings of numbers or letters  of 
any type.  The dealer building using these blocks to rebuild an  engine 
was to stamp the same numbers on the replacement as were on the  original 
block.  There were also replacement short blocks for 80, 98,  102, 95, 
110 and 140 engines.  The engines had the normal T numbers  with a 
sequence of X's and O's indicating its camshaft and crankshaft  installed 
in the short block.
