I'm planning on doing an L67 swap in my 87 GT, but don't know what to do for a clutch. I am using a Fiero 5-speed trans with the 3800 and have a flywheel from a same-year Camaro that I will have balanced for the 3800, but don't know where to find a swap clutch for this car. I need suggestions from people that have done this swap before.

Did u have the flywheel cut down also? Go with SPEC 3 or SPEC 3+.....
I wouldn't worry about the clutch as much as I would worry about using a light duty transmission specified for a 140HP engine with an engine that will give you 240-260HP. Not to be rude but everyone that I know of that tried to use a more powerful engine has either had problems or has blown apart the Getrag tranny. One guy that I know with a 3800SC, blew the Getrag case to pieces on an all out launch. IMO, the 3800SC works best with the heavy duty 4T65eHD automatic.

I bought the spec 3 for my swap, ill be doing the actual swap next spring. In doing some research since I bought it I found concerns about chatter while shifting off the line, but I already bought it so I guess I'm stuck with it. I should have went for the 3+ which has a better reputation for being smoother and still taking the torque of the 3800sc.

thanks for the suggestions, I'll probably go with the spec 3+, but what TOB should I use (it was mentioned not to use the supplied bearing)? I have not had the flywheel machined yet, but plan on having it cut and balanced at a local machine shop that I've gone through before. Also, the reason I'm using my Fiero 5 speed is basically because I already have the trans and axles for it, I don't plan to use it as a drag car or anything, just daily driving, so hopefully it will be okay. If I do end up destroying it, I will most likely get an F23, but my budget is limited at the moment.
Sorry for the slight hijack, but it is the same conversation so why have 2 threads?
Are the splines on a 3800 Camaro's clutch disk different than the Fiero? I need to ditch the Spec3 I have been using. My wife wants her Fiero back and I want my Camaro back. She doesn't like how hard the Spec3 clutch is. So the deal was made that if I replace the clutch with something that has more of a stock feel, she'll drive the Fiero. As a bonus, I get to build an ALL OUT whiz bang faster than stink Fiero with no creature comforts. So I was wondering if a stock 3800 Camaro pressure plate would work with the Fiero disk. She won't be thrashing it and the L67 is stock. So slippage shouldn't be a problem. I just need a soft pedal with components that fit and work.
I have found the Spec3 to grab fine and not slip but it chatters like crazy and it's an on/off switch. I was told that this is because of the lack of springs in the clutch hub. It's a solid hub.
As for using the Getrag, just don't dump the clutch at WOT. Shock load will kill it behind the torque of a 3800SC. Shift easy and then roll into the throttle. If you plan on abuse, an auto or an F23/F40 are recommended.
Well my recommendation for a clutch that isn't as aggressive would be the Spec 3+ it isnt a pucked clutch like the stage 3 and has more of a stock feel. Also the spec stage 1 would probably hold more than a stock fiero clutch and hold up a bit better.
