And you probably need the special spacer that goes between your TKO and the block. If you need it, and you don't use it, you'll do a real number on your engine because the nose of the transmission shaft will bottom out on the crank and try and shove it out the front of your car.

Should have bought a LS9, Hemi,.....lol

What the hell, what spacer ?

Here is a thread that discusses the need, or lack thereof, in detail. Tremec TKO to Ford FE - Input Shaft

[FUNFER2]

With the install of my first 428 anf Tremec 3550, I did not use a spacer and I just used a nice condition, 26 spline tool from a guys box that were full of them.

But, I'd rather not take a chance. So help my find the parts at Summit and I'll make a order.

If you call Mike Forte, I bet he has one of his beautifully crafted alignment tools just sitting in a box somewhere. But, regarding the spacer, alas I can not tell you whether you need one or not. You have to measure. Remember, you have two goals: 1) Don't let the nose of the input shaft push up against the crank shaft and destroy your thrust bearing thereby sending shards of metal pumping through the rest of your engine; and 2) have the geometry of the transmission, its mounts, where the shifter comes out on the tunnel, the length of the drive shaft, all work out properly. As a general rule, you will need a spacer if you have the long shaft on the TKO, you will not need the spacer if you have a short shaft on it. But you have to measure to be sure. Don't trust your engine on a "general rule" and just bolt shi* up together with a hope and a prayer that it works. Read that thread on this issue and note post #8 by HSSS427 and the importance of the bellhousing dimensions. Mine is a Lakewood, I have a long shaft in the TKO, and I use a spacer. Don't rely on me, though. Measure, then measure again, then post your measurements and ask for a sanity check from the gallery.

By special spacer between the TKO and block, do you mean the bellhousing?

Alright, but it is between the the transmission and the block, just not right up against the block.
