Default 400 swap in progress. Quick question.

Car is a turbo car so I’m running solid motor mounts. I’ve got the 4 bolts along the “sides” of the transmission but I’m having issues getting to the top 2.
I’ve loosened the motor mounts and still can’t get the motor to angle down enough (even with the weight of the transmission hanging off the back) to reach them. I’m guessing next thing will be to drop the K? Just looking for any advice really before I carry on. I could easily be missing something simple.

Take the intake off and reach them from the top. That's how I did it

Good point. I was able to drop it enough to see the one offset to the right from center. I never was able to get the bolt started though. I’m guessing it probably is a standard housing though since it won’t start. No problem tightening the other bolt though with the intake off though from the top??

Which solid motor mounts do you have? I have UMI's solid motor mounts, which indicates left/right,top/bottom. I used long extension and swivel sockets to bolt the trans to the block. And it takes time and ALOT of patience. You'll get it!
Btw, thanks for your shifter mounts, they're perfect fit! Good luck with your swap.

I can’t remember which mounts I run. I wanna say they are umi but it’s been 3-4yra since I purchased them. I’ve got swivel sockets and the extensions. I just can’t get it to drop low enough to see. I’m goinf to try and take the intake off tonight. I’m hoping that will make the last bolt easier. Don’t wanna fool with dropping the K. Your welcome for the mount! I’m glad it worked so well for you.

You won't have to drop the K member, nor remove the intake. Ask someone with small hands to reach and just start the bolt for you... girlfriend, wife...lol.

The one to the right of the center there's not a threaded hole on the bock for it, no bolt goes there even though it has a hole on the th400 housing. I had no problem tightening the bolt once the intake is off. I'm pretty sure you done plenty of intake swaps it only takes about 15 minutes to get one off LOL.

You don't have to completely drop the K member, just loosen the bolts 3/4s of the way. This should give you an inch or more of a drop. Shouldn't take more the 5-10 minutes with a 1/2 drive impact.

Thanks guys. I did try loosening all the bolts on the K to allow it to drop a little more and it just wouldn’t work for the top bolt. I’m guessing the solid mounts just wouldn’t let it move. Took about 10 minutes to slide the intake off and another 10 to make 1/16 turns on the bolt but the transmisson is finally secured

Definitely some great info on the stock bellhousing bolts of the 400. I would still be down there trying to get that last bolt started if I hadn’t started this thread. 🙄
