Default 5 speed ?

Has anyone put the V6 camaro 5 speed behind a 5.3? I am about to put a 5.3 in to my chevelle and don't have the kind of cash it taked to get a t56. I am not looking for a all out race car just a driver.

So I guess the question is can it be done, will it last or should I just put a 4L60E in it?

The V6 5 speed will die behind a V8, soon.

As 72chevelle6.0 stated, it well be a DD, It should last as long as you drive it as a Daily Driver. They are rated to around 240 ft/lbs (or less). If you can, go with the 4L60E.

If you do go with the T5, make sure it is a WC one and not a NWC.. you will have to use swap parts for early SBC conversions. Seem like it would be more costly to get all of the bell housing, flywheel and throwout stuff if you don't have what the swap needs for the T5 (or SBC) to a Gen III/IV engine.

I know this is a dumb question but what is the differance in the WC and NWC that you speak of?

Are you saying that I need to get an older T5 that is a world class T5?

if you don't have the T5, go with a 700R4(4L60), if you have the T5, hope it's a "world Class", if it's not, I hope you've got a boat that needs to be anchored. But really. The V6 version of the T5 is THE weakest version of the T5. Then comes the "regular" V8 version, then the world class. I don't think there is a "world class" V6 version.

No..
NWC = Non World Class, which is the older and weaker ones..
WC = World Class, which is in the new cars and rated a bit stronger..

And as far as other stating that it will not last.. Well it can if you drive it as you stated you would, I have blown up one NWC in my 84' Z28 with a 350hp engine, but it took about 35k (124k total on it before it blew) of driving and about 30 trips down the 1/4 mile strip and a few of Solo2 trips every year since I swap to a 350 from the 305. (14.75 1/4 time in daily driving trip. street tires at 20 psi..) So, If still in good condition, It should last as long as you treat it well. Using a WC one now in it. Still holding up.

Some background Info...:
WC designation began in ’85 with Ford using it in the 5.0 Mustang first. F-Body began using WC units in ’88. The S10 didn’t use WC until ’93. The differences between WC & NWC are principally in the bearings & synchros. Externally, there is one readily identifiable difference between WC & NWC and that’s the front countershaft bearing retainer. The NWC has a one-piece design that looks like a large welch/freeze plug while the WC has a two-piece design that looks like two concentric circles.
