This is a 5.0 block rebuilt and I'm putting a T5 in with it. We are using the T5 bellhousing and the cable clutch conversion. Since my dad likes to do things uphill and work against himself, we are working with the old stuff and keeping the 28 oz balance. So he talked to a bunch of people and supposedly found the right flywheel, from a early 70's mustang/truck or something like that and drilled for an 11" clutch assembly. So we are getting closer and closer and go put most of the stuff together for a trial fit and he says we don't have enough room .. apparently this clutch assembly is much thicker than the one originally on the 5.0's and therefore we are running out of room in the bellhousing. We actually had an old 5.0 clutch that we compared it to and it's like 3/4 inch taller. This is the three prong style clutch versus the diaphragm style in case it matters. Any ideas?
