how common of a problem is this? ive never had an issue even with custom cranks and block mods.
I do this with every new/used block I/m gonna run.. I
dont see much run out on autos but its still more than
I like so I mess with it... sticks bell housings for some
reason tend to be more out of spec.. the first stick car
I built was like .035 out of wack... in a stick car its
more important than a auto.. in a auto you tend to get a
seal leak at the pump if its bad enough and after time it
will leak... its a PITA to empty the case your gonna use
if its ready to go.. but on a first build its advised (by
first build I mean the first time the engine and trans will
be run together).... can you maybe get away with a auto...
maybe... thats up to you... a stick... I would do it with
EVERY different bell housing that gets bolted on
