Impros 11/17 148?, surpriced it can pull it. The ET's do have alot of bottom.
No it was not lol, you see when you try to stuff larger sleeves in cases designed for 701/760 displacement. You have to make room for them, what your seeing is epoxy. But it was not damaged at one time, it was added as a strengthener/filler material so that Art could hog the cases out for proper sleeve clearance/porting. Perfectly normal
