The max I would take off the crank is .100 this gives you 2.00 rod journal and stroke of 3.75 I know some people have cut other stock cranks farther, but a LT-5 hollow crank??? I would not like to find out the hard way.
If shipping is a problem, getting the block here and back wont work for the 4.100/125. Unless AES or EES is selling the liners now? Last I heard they only do short block assembled. So your looking at sending 4" liners over sea's.

3.75x4.00 = 377ci

Go with Ron Woods HD liners punch it .060 over = 388ci.
