yes you can As you might know it will create a smaller combustion chamber. So i would check valve clearance although i dont think there would be any problems with that.
This question needs to be clarified. What block and heads do you want to install? Chevy, Pontiac, Olds....which one?
Yes.
with rivets
1966 289ci Ford
1964-1966 smallblock corvette's to be more precise, the 461 smallblock chevy heads.
Mounted on the engine block drivers side below the P/S pump.
yes
350 and 327 [1966 - 1980]
It screws into the engine block right above the oil filter.
An intake from a Pontiac 400 will fit a 389 as long as the engine, or more specifically, the heads are from model year 1965 or 1966.
look on the passenger side of the block below the exhaust manifold and before the oil pan.
