Okay, i did a bunch of reading on ck5 about putting the bbc into a blazer. It looks like there are a myriad of options as far as front crossmember, mount perches, and mounts all of which put the motor in a slightly different position. it also looks like most people with automatic transmission are just bolting the bbc up to their 350-205 combo.

What I've got at my disposal is a complete 2wd 72 1-ton. One question would be: do the 2wd bbc mount perches bolt to the 4wd blazer crossmember? If so how would the engine placement be?

Either way it seems that the main areas of concern are firewall clearance for the valve covers and for the distributor. i am hesitant to dent or cut up my prestine firewall, but the bbc sure is enticing. It is unclear to me how to oil pan fitment works out. but it sounds like it varies depending on pan type, perch type and crossmember type.

Overall it really doesn't seem to be that complicated of an installation. is there something else that I have overlooked?

What is the weight difference between a fully dressed bbc with a/c and a fully dressed sbc with a/c?
