imo rear engined cars are a bit shit as there far too noisy and get very hot in cab, unless you can fab an awesome divide between engine and driver which is even more hassle.

if your going to all that trouble of cutting the back end out, just to fit a pretty crap engine. i'd just fit a v8 the right way round and run a rear diff.

i know its a lot bigger job, but if i had the fabrications skills its what i would be doing.
