No direct experience, but it's basically a Performer Vortec intake manifold and Holley carb, and drop base air cleaner, so it shouldn't have any problem fitting under a stock hood.
It's far from a "bolt and plug in". You've got a high pressure EFI fuel system, this is an old school low pressure carb mechanical pump setup. It has a large coil-in-cap distributor with vacuum and mechanical advance, you have a small cap divorced coil computer advance system (different wiring harness connectors will be required). If your car was a 350 from the factory, you have long throttle cables, and other little things like the upper radiator hose will need to be changed. The carb will require an adapter to mount the TV cable for the TH700R-4.
Some modifications will be required.
Okay, many modifications will be required.
Have you considered getting the base ZZ5 and keeping your TPI? (Assuming, again, that your car was a factory 350.)
