I have crank hubs made for all the different engines i've built and the degree wheel bolts to the faces of these hubs. Most kits however only offer components to allow the degree wheels to bolt directly to the front of the crank, so make sure you drill and tap your crank snout if you haven't already or you wont have any way to affix the degree wheel to the engine. I also have a cam degreeing tutorial that I wrote as a tech article for several national magazines that you can use as a backup to help step you thru the process. I can email it to you if you need it.
