Pete is correct;
I had to remove some material from the starter flange on the bell housing in my application.
I have put together a Desoto big block flat 6 using a Plymouth bell housing and flywheel. You can use a 4 bolt flywheel on an 8 bolt crankshaft as long as there is no fluid coupling (standard clutch). And in this application the nuts also go to the engine side.
I bought special bolts for the flywheel as I wanted to make sure the shoulder was long enough. I then had to cut the bolts to length.
I have put close to 5000 miles on my car after this install and it works well to date.
