i currently have a .020 crank. i am using acl .020 bearings and my clearances are .0015. if i use a .019 bearing with my clearance be .0025. this may sound like a stupid question i just want to make sure my thinking is correct before i waste another 180 on bearings.

its a 6.0L that is turbod going for 1000 fwhp.

 

If that is an iron block I would go with the .025 and make sure I had a good oil pump to move lots of oil through the bearings at that power level. The .015 might be ok on an aluminum block and less power.

 

it is an iron block. i have a tsp ported and shimmed oil pump. i would assume it would sufficient for what i have.

by .025 do you mean .0025 for the bearing clearance?

 

one more question....

who make .019 race bearings. all i have found is the rod bearings.
