Default T5 from as 90/91 Camaro z/28 V8

I'm going to convert my 76 L-82 auto with a th400 to a manual 5 speed. I have some questions about this transmission. I think this is what I should be looking for to get a 5 speed in my 76 L-82 sb350.

Few questions:

1. Will the bellhousing that came with this tranny from the 90 or 91 Camaro Z/28 350 v8 work on my car?
2. Will the clutch, etc that came with this setup work too?
3. Does anyone know what kind of transmission mount I need to make this work. I think these chevy t5's are off 18 degrees?
4. Will I need to move the shifter?
5. I have a th400 today, I think I will need to shorten the driveshaft. What about the yoke?
6. From what I can find I believe this is a World class T5. Anyone know for sure?
7. Anything else I need to be aware of? Do I want the speedo cable from the camaro too?
8. Who has dropped a t5 from a Camaro in their c3? Any advice?

Thanks

Any thoughts on this?

Found another t5 out of a 2001 camaro z/28 that comes with the bell, clutch, etc. Wondering if these parts will work for me. I don't want to buy a Bell, clutch, etc I cannot use.

Thanks for any advice.

T5 out of an 01 would be from a V6, wrong spline count, wrong ttrans/bell housing pattern.
01 Z28 would be an LS1 T56.

The camaro trans will work fine behind a basically stock engine. If you put a much power into them from a warmed over motor, T5's won't last long.

As I understand it they only put t56 transmissions in V8 cars. So I think either the T56 or a T5 out of a V8 would work.

Is the question of whether the clutch will work due to the spline count?

The V6 trans are weaker. They have a 14 spline count, you'll want a 26 spline. The trans/bellhousing is actually a Ford pattern that mates to a V6 BOP bolt pattern bell housing.
You'll want a 83?-91 camaro/firebird T5 that was mated to a 305. BTW, they never put a T5 behind a 350.
As for bell housing clutch linksge, depends on if you want hydraulic or z bar link.

I agree, sticking with one out of a V8.

I *think* GM didnt start putting WC T5's in Camaro's until 1986. So I think I want at least a 86.

I would go this route in my '81 if i could find a mount for the transmission. I'm surprised no one manufactures a mount that will just bolt up.

Ya so with the GM you need a trans mount. With the Ford T5 you need a adapter to the bell housing. Not sure which one is harder.

I do know that if you use a Late 80's to 91 Ford T5 you can buy the adapter from wilcap.com. So maybe that's a better move???

With the ford trans you'll need the adapter, an adapter pilot bearing, and a hybrid (10 spline) clutch.
Making a 15 degree trans mount would be easier/cheaper.

Ahh. ok, So going GM WC T5 is easier than going Ford.

There is another possibility with the Ford trans.
You can swap a 2.95 GM input shaft into a Ford T5 with 2.95 1st gear.
The Ford trans/bell housing pattern wont fit a GM bellhousing, but an 86-89 Astro van housing (4.3/T5) has dual GM/Ford bolt holes. The trans/engine bolt pattern is standard chevy. And you can use any 26 spline GM clutch.

Been playing around with this conversion for some time now. Try these forum threads for a lot of info on the topic. However, there are areas that you will have to figure out stuff for yourself.

http://forums.corvetteforum.com/c3-t...nsmission.html

http://forums.corvetteforum.com/c3-t...onversion.html

The GM WC T5s were in '88 and later Camaros, but went to a Ford type mounting pattern in '93, IIRC. The Ford T5 input in the '94-95 Mustangs are a bit longer than the earlier years. The Ford T5's are supposed to be able to handle a bit more torque than the GMs, but none of them are strong enough for regular high-hp gear banging.

I bought a rebuilt '94-5 Cobra (supposedly) unit for the conversion in my '73, along with the hydraulic bell housing, master and slave from a mid-'80's Chevy pickup. When it came time to actually have the adapter(s) made, I ran in to the problem of determining the exact spacer measurement to get the input shaft to insert into the pilot bushing to the original depth. The distance I measured (relative to a GM T5 along side for reference) did not agree with the info I get from the forum articles and the tranny rebuilder. I'm to the point now that I intend to go back to the rebuilder to see if I can swap for another GM T5.

If you pm me your email address I will send some pics of the Ford and GM T5s side by side. The Ford unit is rotated 7* and the GM 17* relative to the horizontal mounting face of the trans mount. The bell housing I am using will require the modification of the trans mount as the trans will be straight up. In the pics I took you can also see that the location of the shifter mounting box is substantially farther back on the GM tailhousing. A custom modified shifter will be required in any case, as far as I know. I think using the Camaro bell housing to cant the trans over 17* may cause a problem getting the shifter to land in the correct position-----I don't really know about that, but would really like to hear about any experiences of others that have done it, or tried.
