84 380Sl engine stumbles

n/a 1984 380SL- bought car with seized engine, replaced with 60K engine from 85 380SE, new rebuilt trans from MB. Installed new fuel pump, filter, plugs, wires, cap, rotor. Engine starts great, rev's great, put in gear and accelerate slowly,and every thing seems ok. Accelerate too fast and engine will stall or start missing. It will get up to speed and seem to run fine, although it feels like it has a slight miss. Come to a hill and it starts missing very noticably but will maintian speed. Car will surge when on cruise control, I assume becouse of miss.

1974 450SL -mechanical door lock problem

My mechanical door locks work well -from the inside of the car, at least. I cannot unlock either doors from the outside, using my key. It looks as if the key doesn't travel far enough do disengage them.) I'm thinking there must be some problem with adjustment of the two long arms that travel from the lock mechanism to the interior door locking lever? This problem is driving me a little batty.

The vacuum locks don't work, either, but I'm thinking that's a separate problem to be resolved AFTER the mechanical locking issue.

Tired 87 560sl due for engine

A while back I purchased a 560sl to join my mercedes fleet. I thought it was a good deal, but it has white smoke upon start up. I am currently doing the repair/replace analysis I began thinking that while I was at it, it would be nice to get a little more horse power out of it. In researching the internet, I found that the sl 560 was de-tuned for the US market, that the SEL/SEC has more horsepower. Also when investigating, it appears that used sel/sec engines are less expensive than the sl motors.
