Bobsprofab makes an adapter. Don't know if you could use the NASCAR bell with an 833. If that worked you could save a lot of aggravation.
If you have a stock K-member or even a tubular you are going to either raise the engine to the sky or need to get a custom pan done. You could make a wet sump pan and run a single stage pump but, you have to do some work to the engine so the oil can drain from cam tunnel to pan.
I have everything you need. Fresh R5/P7 complete engine, stainless tri-y headers, bell housing with 7.25" triple disc clutch and flywheel along with the starter. All for $5500! PM me if interested.
