4 Speed Swap

I am doing some research on swapping a 4 speed into my car. It's an 88 Firebird with a 305. I read that the only year you could get a 4 speed in a third gen was '82 and that it was a ST-10. I just want to clarify whether it had a mechanical clutch or a hydraulic clutch. Also, if I were to look for a parts car (stupid question - I know) Is there ANY difference between the setup on a firebird or camaro?

I don't want a T5 - I don't want a hydraulic clutch
I even thought about swapping in a muncie but I have a feeling that would be a serious challenge.

Thanks

Re: 4 Speed Swap

Meh... 82-83 used mechanical clutch linkages. 83 V8 used the T5, then 84 they went hydraulic. Camaro/Firebird mechanical parts are generally interchangeable.

Even if the parts you're looking for weren't hard to come by (being one year only, and 35 years old), I'm not sure it'd make much sense to bother swapping in a 4spd.

Re: 4 Speed Swap

The 82 bell housing and 82-83 linkage are a way to do it. Lakewood makes a scattershield for 82-83 also. There are aftermarket VSSs that can thread onto speedo cable connector at the speedo gear. Some of the 84-up pedals still have the hole for linkage drilled.
Easy enough, as swaps go. The multiple linkage points tend to wear out and the steel parts need rewelded or replaced, and the goofy shape z-bar makes for a poor overall design though.

It is a lot of fun to swap a car to manual. Been there, done that. I would strongly suggest driving your car without overdrive for a while, on the freeway especially. It is miserable to have done an awesome swap that makes a car less enjoyable to drive overall.

Usually, the holiday sauce should be hidden from the retired relatives who con the younger enthusiasts into things that were hot 40 years ago, and aren't today. Like non-overdrive transmissions. Then again, you may be the R.R.

Then tell him via PM, don't bump an old thread that he's probably never going to see.

Re: 4 Speed Swap

It's funny, I literally sold all these parts from my 82 2 months ago. I figured no one would want it. It sold so fast.
