Ls and 6 speed into 67 camaro

Wanting to do a ls swap into my 67 camaro and I’m really wanting overdrive and don’t want automatic so from what I’ve read the ls with a T-56 will work, my question is would I be better off with a donor car so I could get the hydraulic set up for the clutch and all and if so what years work the best? or just buy a motor and trans and buy aftermarket clutch set up... and is it easier to rob all that off a donor car or just buy a kit? Anyone that’s been through this I’d appreciate the info, thanks!

Whoever you decide to buy the T-56 from will have an aftermarket kit to set you up for a hydraulic clutch.

Re: Ls and 6 speed into 67 camaro

2.66:1 1.78:1 1.30:1 1.00:1 0.74:1 0.50:1

These are the gear ratios for a 4th Gen LS T56.

The .50 OD is just about worthless in a 67 compared to the Tremec .064 or ,80 OD

That said you can use a 4th Gen T56. The GM Hyd. TO bearing will work. The clutch master will not work unless it is modified. The clutch will work.

You will also have to modify the tunnel to fit the T56.

IMHO better to go with a TKO600. Cheaper, no tunnel mods and do you really need 2 OD gears?

Re: Ls and 6 speed into 67 camaro

6th gear worthless John? I would disagree with you there. I love driving mine on the highway and dropping it in 6th going 1925rpm at 70mph. Take advantage of your EFI. If your rear ratio is (numerically lower) than a 3.73 I can see your point but most guys that run T56s run 3.73-4.10 rear gear to take advantage it the 6th gear. To the OP, if you want to put a T56 in your car go ahead, if you opt for the TKO 500/600 do it. You just have to figure out what trans and rear gear ratio is best suited for each one.

Are you talking about the GM T56 with the .50 6th? I had one with 3.73s and was only good if I shifted into 6th at 100 mph at 2400 rpm. 1685 at 70.

The Tremec T56 .63 6th is 2160 rpm at 70 with a 26" tire

TKO600 .64 is 2100 at 70 in 5th with 3.73s

Re: Ls and 6 speed into 67 camaro

I think the TKO is fine for cruising etc but there are complaints about poor shifting under hard driving. Google it, donít take my word for it. Fine for most but if you plan to drive aggressively it is worth spending the time doing some research to avoid disappointment down the road.

I think this also has a lot to do with the cam. My C6 Corvette was 1500 rpm at 70 mph and ran fine. An aggressive cam likely not so happy...

I also thought the Holley mount system allowed a T56 without floor mods. Otherwise the Speedtech T56 tunnel mod panel is an easy install.

Re: Ls and 6 speed into 67 camaro

Not to confuse things but the T56 & T56 Magnum are two different tranmissions, T56 is from 98-02 Camaro's & Firebirds, T56 Magnum is the aftermarket trans from Tremec.

The T56 will work but moves the shifter away from the original hole towards the trunk(that direction).
The T56 Magnum, I don't have first hand experience but from what I've read also moves the shifter down a bit but also the tunnel has to be raised, its a larger transmission that Muncie & TKO600.

I like the TKO600 options myself, the extra gear will help while on the highway, I tend to value John's opinion here since he has done a few conversations and myself-none. I'm sure the others make valid points as well.
Some of the problems mentioned that 2-3rd shifting problems arise at high rpm shifting can be remedied with upgrading parts option when ordering trans, carbon fiber blocking rings, etc....How to Improve the Shifting of Your TREMEC TKO Transmission

As for hydraulic clutch options......there are many aftermarket kits/ pieces that will, even the LS1 stuff can work.

Most guys that complain about the TKO are shifting it like a Muncie. It does not shift 2nd into 3 rd using an H pattern. Straight up into 3rd. IMHO the TKO has received negative reviews unnecessarily. It’s an excellent transmission. You can google that as well.

Lots of guys out there running the T56 from 4th gen cars.

Re: Ls and 6 speed into 67 camaro

If youíre going to run the GM T56 I would recommend at least 4.10 gears.

With the one I used I had to raise the tunnel approx 3/4 of an inch using the speed tech tunnel plate

I have not used the Holley mount that says you donít have to mod tunnel.

Don, where in my original post did I mention that no guys were running the T56's from 4th gens. I make mention of the fact that the T56 will work just not in the factory position. Not trying to ruffle feathers but c'mon man.

Didnít man to imply that you did. A lot of negative talk in this thread, some of it from me apparently, although unintended.

Iím out. Apologies to any and all I offended....

Re: Ls and 6 speed into 67 camaro

I have a 4th gen T56 behind a big block in my car. I didn't have to modify the tunnel except to relocate the shifter hole about 4" rearward. It's great having the 2 overdrive gears and use them both but I do run a 5:29 gear and have a 29" tall tire. Makes my car very "cruise-able". I originally had the GM hydraulic set up with an aftermarket plate to mount it. I switched out the slave and master to a McLeod set up when I installed their twin disc set up.

How did you get the engine low enough and still have clearance between the pan and the crossmember and get the engine positioned to maintain the correct driveline angle?

What BH did you use to mate the T56 to the BBC?

Re: Ls and 6 speed into 67 camaro

I used the Holley swap components on my LS / T56 install. The transmission clears the tunnel without modification other than relocating the shifter hole. Holley states the T56 Magnum will clear as well without modification to the tunnel.
