D/Dart + 360 Crate Engine + 122 tooth flywheel = Trouble ?

I just bought a brand new Kevlar clutch disc and B&B pressure plate for the 10" scalloped pressure plate setup. I know that setup would work on a 360 because of the added clamping characteristics of the Kevlar disc.

How does the larger bell housing and D450 headers work? Not much room with the smaller 273 bell housing. Looks like I'd need a new bell housing, 360 flywheel, clutch disc, pressure plate, modified z-bar, roller bearing, and a modified (?) clutch fork. Over a grand in parts?

Maybe I'll have to put a 273 that I have had sitting around for a while. I'll put in a nice hydraulic cam, D4B and an Edelbrock carb. All parts that are laying around.

I have the 10.5 inch clutch and used d450s in my barracuda with a 360, it all fit. However I got all the needed parts from Brewers except the bell housing which I already had. You need to use the clutch fork for the d 450's. If you go to summit look up d450's, look at the instructions on the last page they give you a part number for the clutch fork. You will also need to use a mini starter. If I had to do it again I would use a mini that is clockable . I am pretty close to the header pipe

IMO if you already have the 360 and spent the money, find another car to put that 360 in. You have a very special rare car. If it came with the original 273 Keep it, and try to build it up to make more horsepower if that is what you are after.
