Hi Ant, Rick,
351w spigot on shaft is 0.513" [ Five Hundred and Thirteen thousands of an inch ].
So a sleeve would only have a wall thickness of 0.0115" with your 0.490" spigot...
If you ask me ICE have stuffed up on these, ALL 351w blocks are 0.513" IIRC...THE only 0.490" blocks were AUSSIE Manufactured 351 c with the electronic Bosch Distributor.
The ICE site states that the distributor you have has one roller bearing & one bronze bush, so the gear face that contacts the block controls the end thrust as Ford intended, the roller brg & bush do not. They dont state whether the roller brg is @ top or bottom.
Personally Ant I would not be happy with that amount of clearance @ the spigot even though you are not going to have the oil pump load, yes I realise the ICE distributor body extends right down to the gear & therefore it should be more stable than the Ford setup, but the amount of support is still the same in the block, how nice a fit is the dizzy in the block?, whip the rubber o-ring off & try it..
