Hi all i purchased a 91 eb Fairmont from ebay. Bodys a bit rough , interior is grey velour in fairly good nic . After getting it home i discovered it has a what measured 62mm throttle body( as dirty as it was ) so i took the engine cover off and checked out the inlet and found the magic letters HO cast into it . Just a little bonus to add too the sale .

All stock eb-el 165kw v8 come with a ho manifold,they are rubbish,the stock t/b has a reduced step in it where the blade sits/opens closes,most likely a 55mm stock t/b,they seem larger if you measure the inside lip but alas they are not lol.
As long as your happy with it its all good:)
Anyways you can pick up explorer manifolds pretty cheap these days,they flow a lot better than the stock ho unit.

Ok , my bad . Thanks for the info .
