Welcome to CHR!
The Gen 3 Parisenne's were a Canadian model that was in lockstep with Chevrolet, so your 327 is simply a Gen 1 flat tappet SBC 327 and nothing special other than belonging to your Dad. IMO you will not be at all happy with that old engine in your Camaro, and especially not with the two speed PowerGlide tranny, as you'd be taking a big step backwards from the Z28 350 that you have. You'd be much better off putting money into the engine you have in the Camaro now, and un-doing some of the power robbing pollution controls that were standard in '79 or better yet picking up a newer takeout LS engine/tranny/computer & harness package from one of the salvage operations.
