Remember, I was in the prototype group. I have chopped them up pretty bad and will probably still lower them a little more. I ended up slotting the frame mount faces so the isolator stud could get in and out. Starter clearance is TIGHT but doable after a bit of grinding. Same with the P-pump brace on driver's side, I chopped the brace some and cut the engine mount some. The biggie on that side is my steering pump lines are super tight to the mounts. A steering/vac/compressor combo pump of any kind would not with fit these mounts. Also a vertical oil filter will require cutting to the point of compromising integrity so I'm going to run a remote filter. Yes even a 4BT filter-I had a 6BT filter on there and it wouldn't clear at all. The 4BT filter clears but you can't R/R it. I had to cut out around the turbo drain boss on the block, and the passenger side block plate's bend was right at the edge of the forward bolt holes so I had to cut into the bend so the bolt heads could seat squarely and redrill those holes round as the press had distorted them to ovals. I radiused all the edges as I would cut myself just looking at those razor sharp corners. They def required a couple hours of fitting. I like the fact that I can set everything in without having to weld the frame brackets in place. They make engine placement tweaking about as easy as it can get without one of those foam, faux, engineblock/tranny, test fitter, doo-hickies. I have sent 4 people your way-Even being involved in the teeth cutting stage, I'd order these again as they gave me a ready made platform to tweak. Think of it as buying a sheet of plywood-can't use it as is 99% of the time but it sure beats buying a tree to make a shelf.
I sent you an email eons ago detailing all this with pictures so you could have two sets of plans Ford/GM vs Dodge.
Of all the things I've done with/to these mounts I have one I'd suggestion for you to consider: decrease the angle of the mating faces of the mounts. They are so steep that the isolator studs are a real PITA-so much so that I'm probably going to trim them off a bit next time I pull the engine.
Now I remember! Sorry man, its hard to keep up with my 10 projects sometimes.
I believe you have, the very first go around, I am on version 3 right now, many of the changes based on info you sent me. They still need a bit of tweaking, but I think I have fixed the clearance around the turbo drain boss, as I FINALLY tracked down a 3D model of a 4BT which made it much easier.
I honestly am at a loss as to how I would ever get a mid-mount design to work with the power steering pump/vacuum pump.
I definitely added clearance for the starter on the passenger side.
You had to be difficult and run a vertical filter....
I slotted the engine side mounts where the isolator stud comes through so that the isolator studs are much easier to get in, this was an issue for me as well when installing my engine.
I appreciate you referring some people to me even after all that! Thanks for bearing with me and getting through it all! It has been a big help!
I am going to keep a close eye on your build thread, keep up the good work!
