not rocket science, if i can do it!!
my 29 350 has an "hole" in the front of the intake for putting the oil in,.. my othrr intake did not!, it's o.k. to have an oil filler on you're valve cover, a set of aftermarket valve covers will have these.
keep all you're old parts incase you want to put baby back to origional.
an shop manual that goes up to 1984 or so will give you a pretty good idea of how to do the swap.
you'll need a torque wrench and a good set of gaskets,
take you're time... make sure gasket surfaces are clean!!
you will have to pull the dist , the manual will tell you how,just be sure to set the timing @ 0 on compression stroke and look where the dist rotor is pointing ie # 1 cyclinder
work a step at a time ,keep everything clean!
