as long as it's the same size engine (Probably 3.1), the intake style might be different, so you may have to transfer your intake to the new motor. if the two intakes are the same, the motor will bolt right in.
What year? and what size is the motor?

It depends on the size of the motor!! 231ci to 403ci..............
New for '55 was a 287.2 cid , the first overhead valve for Pontiac.
6x9 & 5x8 6
is my question going to be answered?
That will mount fine on a 7" wheel...but and 8 would be better.
If it is a comparable model year motor and trans to another similar GM full size truck/SUV, yes
If it is a Pontiac 350, any hei distributor out of any size Pontiac motor up to 1979 will work.
