How much horsepower can you get out of a Chevy 305 1978?

How much money do you have? The 305 Chevy is not a good starting point. You would be much better off finding a good 350 and work with that small block. The power is only limited by the amount of money you want to spend.

Is the 400 in a 1968 Bonneville a small block 400?

No there is no "big" or "small" block Pontiacs. The terms "small" and "big" block are Chevy & ford terms. Pontiac blocks were thesame physical size from the 1955 287 right through the last 400 cast in 1978. All blocks had a bore centerline of 4.62 inches, which puts them right between the small block Chevy (4.40 inches) and the big block Chevy (4.84 inches). There were short deck versions built- the 1969-1970 303 race engine (about 25 made), and the production 265,301 built from 1977-1981. ALL 287,316,326,350,347,370,389,400,421,428,455 engines are the same exterior block dimensions.

Where do small block Chevy motor monts mount on the frame of a 1978 Cutlass?

That car is the same as a Malibu. I would find one, about the same year, and take some measurement, then, you will have to weld, or bolt the pedastals in, if they differ from Chevy, at all. I cannot remember what Olds was using by 78, but I know Buick, is the same.
