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.

I have the Spec 3+ and their aluminum flywheel, Series 3 SC with a Getrag 5 speed.

Haven't driven it much but so far it has very smooth engagement, no chatter.

I agree, the Spec 3+ is a great clutch for the 3800sc.

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.

What car is the swap clutch from? Fiero? Camaro? Does it need to be modified to fit in the Getrag?

I would go with an F23 trans if you want to go manual. It is not much more work, and you can use the stock axles from your fiero with it.

I am planning on using my Muncie 4 speed with the 3800sc. If the spec TOB is not good can anyone link me to a better TOB to use with it?

Just a GM factory TOB should be sufficient.

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.
