Hi freinds,
I'm sorry for my late reply, here the news:
I received wiring harness, pulleys for supercharger, belts ..
As my original engine is off and on the floor, i proceed to test new engine fitting.
First problem I met: the V8 is about 15 cm back and cannot fit, so I swapped engine mounts from V6 to V8 and then the result is is OK: it fitted perfectly in horizontal position.
But unfortunatly, I met a second problem, it's in vertical position, the front axle carrier blocks engine to take its good position

.
I noticed that the engine I got was a CL 55 AMG and not CLK 55 AMG, after search I found that the bottom are different Oil Pan are different: the CL front oil pan is bigger than CLK one.
I had two possibilities to face the problem: changing front axle carrier or change Oil Pan, but after search again: Oil pan swap was the ultimate solution, so i order it today from MB dealer (now they know me well and offer me 17% discount

).
As monday is a day off, i hope receive it on tuesday and carry on the deal.
Lantana: what about ECU pics?
keep you poted.
