SBC 400

[dzorde at erggroup.com]

Yes 0.020" end play (moving crank forwards and backwards when mounted in
bearings), according to the machine shop they reckon it was OK as there is an
auto tranny going behind it, but I'm a bit sceptical about it.  Someone has a
vague memory that there are bearings with oversize shoulders available which you
get machined down to the correct shoulder size to remove the end play, any
verification on this ?

<20 thousandths, as in .020"??  Stock specs are around .005" max, so
