I've got my 3800SC swap almost done . it's set up on a '86 CRADLE. ('97 3800SC/auto) the notchie I was "planning" to put it in is a '85 4cyl/auto, thing is, the car, JUST as it is, is TOO reliable and the engine has only about 4k miles. I CAN GET a 1988 Notchie (4 cyl 5 speed) really cheap. Will the same engine/trans "Mounts" work in the '88 cradle ? (To Change from stick to Auto)?? Or, would the 88 5 speed "Put Up with" the 3800SC for long ? I really don't want to "Undo" the '85 4 cyl car, It's just too good. Thanks

Don't know about the mounts but my 85 5 speed put up with my DOHC just fine but then again I did not do a lot (ok NO) clutch dropping starts. The only thing I found on mine was that the spread from 1st to 2nd was pretty big and the shift was 'slow'. I'd be screaming in 1st but by the time I got into 2nd the revs had all dropped off. Your mileage may vary in that respect, that was just my experience. It was nice on the freeway though, nice low rpm at 70 mph but oodles of power to just pull away when needed. I'm sure the Sc would be similar.
Personally, I think that if you've got a good reliable Fiero of any sort, it'd be a shame to spoil that.

Anything I might say is probably worth what you paid for it, so treat it accordingly!

The only "Down side" of the 4cyl/auto is the 125 trans (doesn't like highway, too high "reving". The 4 sp OD auto will be nice. I never know what I'm going to do until 5 min before I DO it ! LOL

I know exactly how you feel. I have an '85 GT with the stock 2.8 and it runs as reliable as any car I've owned. I'm going ahead and taking the plunge to a 3800sc, but the 2.8 is going back into an '86 GT, so at least I know it's going to a good home

I believe, from previous inquiries from myself, that the stock v6 manual trans would hold up OK. All be it with a much stronger clutch than stock being necessary. I want to say that the trans/motor mounts are different than the pre 88 cars. I know that when ordering conversion mounts, 84-87 and 88 are 2 seperate listings. Also, the factory fiero auto transmissions will not hold the added HP from the 3800, but I don't know what your plans were there.

Someone with more knowledge may chime in and correct me some here, but I think I'm guiding you in the right direction with that info.

What I built is a '97 3800SC with 1997 4 sp AUTO trans (not 125). I'm just having a hard time getting myself to "UNDO" the great running 4 cyl/auto that's in it.
I think I'll just keep the 3800 engine/trans wrapped in plastic for awhile and" think on it". Thanks
