Crank end float, chevy

[kiwicar]

Hi all
I am currently doing pre assembley (1st mock assembly) checks on my new engine (383 chevy) and every thing is OK apart from crank end float, measured it as recomended by various books and it comes out ay 3 to 5 thou depending on where on the thrust bearing I measure it.
Everything I have found says 7 to 9 thou for end float and the machinist warned not to run to little end float because it would "kill the engine in about 20 seconds".
So the question is how do I best remove metal, either from the bearing or one of the thrust surfaces to bring it to spec?. bearings are clevett 77 and the relevent surfaces are plane copper, no white metal coating.
Best regards
Mike

No idea.
Try giving T&L engineering in bedford a call - they might be able to help.

I know on the rover thrust bearings you need to give the crank a knock from either end to even up the faces when you put the cap on - does the same apply to the chevy thrust bearings?

Thanks Elliot
yes part of the measuring set up is a bash from both ends of the crank and then measure both sides of the thrust bearing with the crank pushed in both directions.

Im sure I read somewhere about using wet and dry to size thrust bearings.

On a good flat surface obviously.
