It's not a desirable combination. If it were FI or stick shift it would be more desirable. And it sounds like the engine needs work. So probably not too much.

1971 280s engine an transmission

I had a buddy buy a 1969 280s engine block from me for $75 delivered to his house. I have him the engine head and all the auxiliary components too. Essentially he got the whole engine (which was seized) other than the intake and exhaust manifolds and the carbs for $75, but then again, it was seized. Mainly he paid for my time to pull the block and deliver it to his house a few miles from mine, and offset the few bucks of scrap metal I lost. If the engine ran, I am sure I could have gotten a few more bucks. The guy ended up freeing up the engine, but I think it would need a full rebuild if it is ever used. I think the $75 just pays for him to have something to play with.

I have had offers around $200 for the complete zenith carb setup, but I haven't sold it yet. It includes the intake and exhaust manifolds, and the exhaust heat riser flaps always need work on these. So the extra set should have value for someone looking for a full original restoration. I am holding out for a little more than $200 on mine, but it's been a long time now. Ironically, I sold 1.5 carbs and the leftovers from a few $35 rebuild kits on ebay for about $120 pretty damn quickly. They were all cleaned though.

Take note that the carbed m130 blocks are different than the injected m130 blocks (that were used in 280sl pagodas).

In my case, I determined that the transmission was the same as the one used in the 280sl pagoda cars. This was not the case for many w108. So you need to get the specific part number off the transmission to determine exactly what you've got. Apparently the transmission pump alone is worth over $100 if good, heck even if it's just a core.

I ended up giving the transmission to a friend who hoards parts and has a 280sl pagoda. He will know better what to do with it and hopefully extract a higher value from it than I could (not being a pagoda man).

If you want to pull off the transmission info, I will be glad to help determine if it is the one used on the pagoda cars.

Altogether, I've only got $75 in my pocket after several months.

My dream car is a classic sporty five speed (stick+overdrive) convertible that seats five. If, you want 70's-80's Mercedes tuner wheels, let me know.
