T56 Magnum transmission in '67 Impala

Has anyone tried or seen a T56 Suoer Magnum 6 speed transmission in a '67 Impala? I'd like to know how much tunnel modification to expect and if I could use a factory 4 speed console with that transmission and also still have proper shifter handle placement. Does anyone know? I'd sure appreciate any info on the subject. Thanks.

Finished up my Tremec 5 speed project yesterday. All is well. Had it up to about 90 mph on the highway and NO vibration. The tranny tunnel really didn't need to be cut out as much as the dealer told me, but... I made due. Everything came out good, fit wise ,carpet, console, shifter, maybe an inch or so taller than it was before due to putting the 'Lid" back on after the cut out. Happy to get that behind me. Having a 5th gear....sure is nice

I'm not sure about the 67,but right now I'm putting a TREMEC TKO 600 5 speed in my 68. The console does line up with the shifter, but I had to cut the tranny tunnel quite a bit to make it work .A little taller and wider than my old Muncie.

Thanks for that info Bob. With all that tunnel work, does the stock console fit property over the expanded hump? Does it look right? Best of luck on your project and thanks again for taking time to give me that info.

Remember, the shifter on the 1967 is offset to the left of the tunnel whereas the 1968 shifter is in the center of the tunnel.

In regards to the console fitting.... I still have the seats and carpet out but, I have taken the part of the tunnel that I cut out,and mig welded 3 strips of 2 inch metal on the sides and top towards the firewall, made it kinda like a lid. Plan on putting it right back in place and using rivets to secure it. I was able to place the console on top of the bare metal and see the bolt holes in the middle and rear of it line up just fine with the new shifter coming up through the floor in correct position also.

Have not made it that far yet,inside of the car is not back together. I don't think it will be that bad though. The crossmember is my issue for now.I bought a complete kit,..supposedly... The crossmember that came with it doesn't support the tail shaft of the tranny high enough so I'm gonna have to add some rubber under the isolater and use longer bolts to make it work.How much higher is the question now.Drive shaft angle is important .When I'm done I'll send you a pic of the console.

What about carpet? Will one of the reproduction carpets still fit properly in the car with the hump so much bigger?

Can you share whose kit you bought? I have considered the TKO 600 as well.

thanks

I got it from a place in Tennessee called Silver Sport Transmissions. Google that name and it will come up. I also considered American Power Train...both places $$ are pretty close.

I have talked with Silver Sport. Interesting that they claim pretty much everything in the swap is a slam dunk with their pieces. Will love to see pictures of your project.

FWIW, a friend of mine bought a kit from Silver Sport to install into a 1967 Camaro w/327 and PowerGlide. The kit was COMPLETE. Easiest auto-to-manual conversion I've seen. This was the 5-speed transmission and NO tunnel work was required and the shifter was positioned correctly in the Camaro console.
