Changing a 727 to a 833 or a Tremec?

[SteveSS]

Is there some book, manual or website that would give me a step by step guide on how to change a 1970 383 Coronet 500's trans from an auto to a manual? With the proliferation of 5 and 6 speeds i wonder if it's that much more difficult to swap in a Tremec instead of an 833. I'm sure the tunnel would have to be enlarged. Doesn't the tunnel have to be modified somewhat for the shifter hump when swapping to a manual?

If you are looking for a 4 speed and all the parts for a swap, I would just call Brewers and they can provide everything you need. Otherwise you will go hunting for a year to find everything and only save a little money. For the 4 speed swap steps, this post on Dodge Charger is one of the best and what I followed when I did mine. How to do a 4 speed swap...with pictures!

Tremec will provide most parts you need and the new TKX is supposed to slide in with little to no tunnel mod. Here is a decent video on the swap in a Charger -

Tremec 5 and 6 speed conversions come pretty much complete, but you're gonna pay for it. The magnum 6 speed is like $8500 now and doesn't even include the driveshaft. Being just shy of 10k by the time you're done seems pretty crazy. I had looked at Brewers a few years back and they were about $2500 cheaper for the swap, but that was to get an original 4 speed. Its actually more work on the tunnel to swap in an original manual than to swap in the magnum. If going the tremec route, given the costs new, you can source everything separate and save decent, then maybe order the trans only from them so the shifter is located properly. can save more going used and refurbishing or just sending it.

Tremec from SST. Minor sheet metal mod.

I bought a used 833 o/d, used bellhousing, new flywheel/clutch/ pressure plate for around $800.

My automatic '65 already had pedals in it. I'll use a Mopar driveshaft I have in stock and cut it myself.

I had to buy a shift lever. I'm using a clutch slave cylinder and master from my dirt car parts stash.

I guess I'll have one G in the whole deal.
