I think Chris said our new searchable forums would come just after the pigs took to the air or something encouraging like that I've been watching but nothing yet....
The 276 figure is right and all 455HO Formulas for '72 had ram air mandatory. On the transmissions, it's not known specifically for the 455HO Formulas, but if you go by the T/A numbers for '71-'73 I'd bet it's pretty close to the same percentages:

'71 T/A Auto 58.2% Manual 41.8%
'72 T/A Auto 64.4% Manual 35.6%
'73 455 T/A Auto 68.8% Manual 31.2%
'73 SD T/A Auto 71.4% Manual 28.6%

Thanks RicksGTO,

I did not know the RA was mandatory with the HO. The PHS shows it, so I guess it was a package deal then. I am just starting to learn these 72 monsters

Ok, to add (or subtract) to the stick percentage, what would be a good guess at this car with the M22?
Oh, these were 12 bolt like the 72 GTO's as well right?
