[Tigers] K motor Block and Crank

[Carmods at aol.com]

It appears that I miss spoke when I described the Hipo 289 block as having  
four bolt main bearing caps. I should have said the following.
 
 The Ford rough castings of the standard 289 and 289 Hipo were the  same 
with the same casting part number.  The blocks that became HiPo's  were then 
machined different for the larger main bearing  caps.
 

The standard 289 and 289 Hipo cranks were also the same casting. Hipo  
cranks were selected for hardness  based on a single Brinell test. 
 
There will be a visible indentation on the crank  indicating that  the 
crank was tested.  This does not mean that it was actually a Hipo crank  since 
the cranks that were tested and failed to meet the hardness requirement  were 
then used in the standard 289 build.

 

Please forgive me, perhaps I'm getting forgetful. I think I made a mistake  
once before but I can't remember.
