Am I doing something wrong? SBF & T5 fitment issues

[ztoolman44]

Serious question. Am I doing something incorrect here? First the factory header hit the motor mount plate, now the drive shaft hits the frame/cross member. I have no problem modifying things and am happy to do it, however considering I am running all OEM items that the kit is designed around, I want to ensure I have not messed something up from the get go before I start to cut and weld stuff.

The transmission mounting boss is sitting about floor level and the drive shaft hits the bar under the tunnel support/drive shaft hoop. There seems to be plenty of room between the cross members behind that area but I am not even close to the rear end sitting at ride height. Like 1-1/2" to 2" and that is with no suspension droop.

Wondering if I have the transmission mount in wrong or if there are different, taller motor mounts I should have purchased. Everything is new and OEM. Kind of a head scratcher. Are any of you guys or gals running a SBF and a T5 in the truck or hotrod?

Things changed around a little on the Gen 2 so I can't speak to the driveshaft issue, but I've heard similar comments.

On the header issue, the "factory header" (which I assume you mean a standard SBF exhaust manifold) isn't intended to work. Pick up some BBK 15150 shorty headers and you shouldn't have any interference anywhere and the FFR exhaust J pipes should connect up just fine...

By factory header I am referring to the shorty headers that came on the mustang donor. Passenger side does not fit. I have a few work around ideas, just want to make sure I am on track before I start throwing sparks.

Completely different engine and trans in my truck build (LS3 and automatic) but my driveshaft initially hit in the same frame location at full droop. Took a combination of adjusting the rear height of the transmission, adjusting the upper link on the 3-link for the proper pinion angle, and then mounting the coilovers in the top frame mounting hole (a suggestion from another forum member) to limit the droop. Mine just clears now. Likely will rarely if ever drop that far while driving. But if it does, won't hit. Another option, which I considered, was limit straps. But wasn't necessary.

I would be inclined to believe I could adjust things if it was only hitting at full droop. Mine is hitting while sitting at ride height and not just barely but by quite a lot. This is why I am wondering if I have something installed completely wrong.

I'll try the upper mounting holes to see how much that gets me. Maybe add some weight to the bed or shorten the springs a bit. Perhaps there is enough adjustability.

Thanks for your thoughts.

Those are not intended to work but if you want, fab away.... :)
