3.1 to 305 swap
OK here we go.
I have a '92 Firebird with the 3.1 and 700R4, I am buying a '89 Camaro with the 305 and 700R4 in it, and am going to do the swap, The Camaro is trashed out which is why I am not selling the Firebird and keeping the Chevy. the engine and tranny in the Camaro are in great shape with all wiring harnesses etc. I expect it will take about 4 days to do the complete swap, can anyone give me any ideas that would make the job go smoother? The camaro is complete, so all the parts I should need are on the donor car.

clean everything before you start, take them to a car wash and hose everything you can off. not any real short cuts to doing it, just start spinning wrenches. i'd drain the coolent before i moved the car to where i was doing the swap. i believe you'd have to really work at it to be done in 4 days, but i'm slow so maybe you can.

Baumholder, eh? I've heard of that. I did a V6 Vega swap in Mainz in 1980 (man, was that really 20 years ago?).
Are you doing this in the craft shop? Is that your 4-day restriction? I'd think you're in a good bit over a 4-day job, even if you're faster than ede. I spent at least that much time taking things apart, but I marked and tagged everything when taking apart both cars. That, by the way, saved a bunch of time when it came to putting things back together. The front engine mounts & springs (which should be done at the same time), and fuel system change-overs are going to be very time-consuming. Take pictures before you take anything apart, and more as you disassemble - another minor investment that can pay back big dividends.
Take the A/C's out as complete units while the engines are out - it can be done, and will save having to recharge the V8 system when you put it back together. The exhaust from the cat-back can be taken out as one piece also by taking off everything that attaches to the right side of the rear end (probably easier than cutting and welding the exhaust).
One problem I can think of is your Camaro V8 tach won't fit in your Firebird, and the V6 tach won't work right. Another thing to consider is you are putting an older engine/emissions system into a newer car. Technically, this isn't legal, and could cause problems if/when you bring the car back to the States. The 89 is MAF (if TPI), and 92 V8's had speed density (if TPI). TBI's might not be a problem.
