I am using the ford v8 not the rover , has the same install problems though. I have made up a flywheel using a diesel mitzi shogun ring gear <12" diameter> That takes a tvr twin plate clutch. Engine has a back plate with the mitzi reduction gear starter, that just leaves me to make or modify the getrag 265 bellhousing.or buy one of these

Also the top of the cylinder heads are only 40mm above the top side rail of the chassis, there is also loads of room for the headers and steering column.Cant see the rover being much different other then its about 4" taller. Here is a v8 locost
