Engine block design

[schISM]

Cat built one heck of an engine in the 3400 series(A,B,C all the way thru nxs). The last version, sdp, was a lesson in Rube Goldberg engineering. Still a good engine buried under the emissions garb but it put more than a few truckers in a financial bind.
I've got a bxs setting in the shop that I've been slowly building up. Had the block and head hot tanked and magnafluxed, the crank checked for straightness and micro polished and an adem III ecm for a 6nz conversion once it's all built. After seeing all the components apart and comparing the size of the crank for example with an isx its no wonder these engines can push 2500hp, they are stout.
