I installed the engine last weekend. The swap went very easy, besides being a very tight fit on the firewall, it was easier that putting longtubes on a foxbody.
words of advice to anyone who attempts this is to make sure you leave the headers off and before installing them, dent in the runner next to the steering shaft, measure and cut the battery tray, you will have to put wider fuel crossover lines on the rail and the intake sits well above the fender.
All of the stock wiring worked and the blower is situated in a much better location that when mounted to the 331.
