yep. 383 is basically a 350 with a 400 crank. Besides the flywheel/flexplate and balancer, everything will bolt right up to it.

all chevy smallblocks AND big blocks have the same bellhousing bolt pattern! but, there are differences in the flywheels!
a 383 will take a 400 flywheel which only fits the 400 and is externally balanced. let me know if you need one, i've got a brand new one sitting in my stash!

you must be refering to the one piece seal and the flywheel interchange. the bellhousings. are the same you would just have to use the flywheel that matches the style of crankshaft you are using.
