I imported the box from the US and it was to fit a Ford modular engine. The GM one has a shorter extension housing so that would help my possible issue re tailshaft length, but not my other issue re the engine being longer than the Chev. Yes, I do have a serpentine belt system and a smaller diameter pulley would allow me to lower it somewhat, but not sure it will be enough. I'm checking to see how low I need to get the crankshaft centre down to see if that might be a possibility. If it wasn't so hard, I'd post a photo!
