That 305 won't make a good anchor IMO.

The company of men who seek the truth is much prefered to those who think they have it

two bolt will be fine ... there are a lot of good old threads on here about the 400's so use the search feature and settle in and start readin ...
Don't waste your time ... it is the only thing you can't get more of
.. if it accidentally looks like I gave advice please ignore it .. and notify me immediately

you might also consider looking for a 454, more torque. Bud
