Finally doing up a S80 the way I've wanted for some time - with a modern EFI V8, and overdrive auto trans. Currently mocking up with a Vortec 305, to replaced later with either a 350 or 383 (although we breifly contemplated dropping in a 496 ) I've been going back and forth on axle choice, mainly whether I'll be running full width or not. I still haven't decided I will be running a 36-37 inch tire, likely leaf sprung for now, and eventually moving to a double triangulated setup front and rear down the road. This round of pics include using TH400 trans to help give a better idea of where to place the engine, but the plan is to use a TH700-R4/4L60. I also apparently forgot to get a round of pics before the chopping began, but I'm sure people can get a decent idea of what the empty engine bay of a S80 looks like We started by unbolting all the sheet metal forward of the firewall, and chopping off what was welded in place The plan is to pinch the front end roughly 16-18", extend the cage up the grill support, and build a tubular framework to hang the fenders off of. I've also been considering perhaps building out a tilt frontend. Not so much for the cool factor, but more so for ease of access to the engine for maintenance/repairs. I don't have fond memories of leaning over the fenders trying to get to the I6 that was in my last 80, and I'm certainly not looking forward to it with the V8 (this was also part of the decision to chop out the inner fenders on this one, along with easier exhaust routing, outside the frame). The V8 does drop in there _real_ nice. To the point that I think it would have been completely possible to get it in there without modifying the stock front crossmember, but it would have been real close, and would have required pulling the engine if the front pulley/balancer ever needed to be removed (like when the front crank seal went south on my I6). So the crossmember came out, and will be replaced a little farther forward, serving as part of the winch mount. I tried to get some shots of the placement within the tunnel..the engine is set back under the tunnel some, basically it's shoved back there as much as possible. At this point, I don't think the firewall/tunnel will need to be modified _at all_..._maybe_ just a little bit around the rear of driver's side exhaust manifold, but I think with a set of center dump manifolds, I will have plenty of clearance. There would also have been plenty of clearance to either of the inner fenders. This is one of the fenders temp hung back on, to give an idea of the positioning of the engine in relation to the front of the truck. Plenty of room for radiator and fans behind all stock bodywork. Granted, I'm using an engine with a low profile "crab cap" distributor, which does allow me to put the engine a bit further back, along with a low profile intake and EFI which helps too. I'm hoping to get the engine actually mounted this coming weekend, and hopefully the trans and transer case mounted as well.
