the 350 balancer will be fine fitting in the truck,, some crate engines don't come with one..
and the 327 balancer is smaller (little over 6" than "most" 350 balancers (7" or8")
thats all I think he ment, the different balancers don't line you with the timing pointers, as the newer g.m. crates the timing cover is plastic.. with the pointer cast into it..
the flexplate or flywheel (auto or standard) will need to be for a one piece rear main seal.
and make sure the torque converter bolt spacing is correct for whatever is in your tranny(if auto) and 153 or 167 tooth for what ever starter you have..
good luck
