Your answer is Yes and No. It is true that the manifold will bolt up the the engine and work. The 400 is a newer engine and there are different ways of attaching external components. For example, the 327 engine had an ignition coil mounted with a bracket to the intake manifold. The later 400 came with the larger HEI ignition that had the coil internal to the distributor. That shouldn't be a problem. Next, alternator mounting. All but the very latest 327 engines used the short water pump and 400's I believe used the long water pump. That doesn't directly affect the intake manifold but you may need to use the alternator mounts from the 327 depending what the application of the 327 was. Chevrolet used that engine in cars, pickups and 2 ton trucks so there were a lot of varibles. If I recall properly, all 400 engines had the oil fill plug in the valve cover. 327 had that oil fill tube in the intake next to the thermostat housing. That may be where you run into problems again with alternator mounting brackets. Same my be true for A/C if you have it. Like my college buddy, now Automotive Proffesor says, "We can fix it no matter what it costs." LOL The best advice for you is to clean up the 327 manifold and set it on the 400. Take a look at all the brackets and mounting locations and then decide from there. If you look at the hotrod aftermarket, they make aluminium intakes for small block Chevys from 283 to 400. One part number covers them all. You can make it work. Just be ready to use some of the old brackets, studs and bolts and some patience to figure it out.

Every 400 I have seen all had four barrel carbs up to and including one ton trucks. Going from a 4 barrel to a 2 barrel will cost you about 50 horsepower according the Chevy's numbers. But then, anything prior to 74 had more compression on the four barrel model and different cam I say if you have it and it works, use it. Good luck. Hope this helps.
