I think I may have to figure some of this out myself,but thought I would ask for some Info.I am going to use a 250 6 cylinder in my 46.As of now I plan on using the stock transmission.I have a bellhousing somewhere that should work.What flywheel and pressure plate will I need.Will the one on the 216 work?I think the 250 uses the same flywheel as the small block chevys.Is that correct?I guess I will fab up my own engine mounts unless there is a easy to do kit that I can buy?Any other info that would help?
