You stock C43 intake manifold is the same as the E55, so Use the E55 heads and your intake manifold. and your exhaust manifolds will also fit and need to be used.

I'm pretty certain you can. But will there be benefits? If you can measure the ports that may prove beneficial. I have a 55 motor on the stand right now and my swap will take place next weekend. I measured the exhaust ports at 36mm if I remember right. The intake manifolds and the exhaust manifold gaskets are the same part number for both cars though. Once I have my 43 motor out I intend to have a look and see if there are any tangible differences.

The C43 heads should be fine, If you have the 55 heads, I would use them . I think the only difference is the bore/stroke of the engine.

We touched a bit on this in a previous discussion a few months ago. Unfortunately, it appears that no one knows the specific C43 cam specs. I think MarcusF put up whatever cam specs he could find on this site. But I'm thinking that while the C43 top end was produced to make more power and torque than a 430 motor, the 55 motor will trump both (naturally). Might not be a benefit to put the C43 top end on a 55 bottom end, but it would benefit a 430 to have the C43 top end.

Guess someone should get out a cam and get it measured. I did search around but didn't find anything. This is probably because the C43 was before or at the start of internet.
Schrick cam measurements are discussed in this thread https://mbworld.org/forums/c36-amg-c...t-details.html Saab was talking about. They are the same for ALL M113 engines.

The things one learns mixing and matching Porsche parts......
Unless you go with a 55 long block & fuel system, the best tune would be one on a dyno using your car and the parts you decide to use. The reason for that is in addition to the cam differences, you may find the 55 valves to be larger than 430 valves. I don't know that for a fact, but I do know the 500/55/55K valves (all the same) are different than the C43/430 valves. Also since the 55 is over 25% larger than a 430, it makes sense that the valves would be larger. If you go with smaller valves, they will have better low RPM flow (but not necessarily at WOT), at the cost of higher revs (& possibly leaner). Which injectors? The ME 2.0 430's? The ME 2.0 55 injectors? The ME 2.8 55 injectors? The later ME 2.8 55 injectors? Do you know what each of those flow? Those aren't questions for me, but your tuner may be interested. Unless of course, the car is on a dyno and the tuner can look at the A:F ratios.

Are you sure it would benefit a 430 to have the C43 top end? I was under the impression that the 4.3 in the C43 is exactly the same that is in the 430's? I didn't think AMG did any porting, or more aggressive cams like they do with most AMG models. They simply stuffed a V8 in a C class and called it a day. That was my understanding anyways...

Yep and I understand that all of the extra power and torque came from modified top end components. Marcus' site has a breakdown, comparing part numbers. I believe most of the 'magic' was down to hotter cams.

Side note,I believe a c43,clk430,e430,Clk500 would benefit from using all valve train parts from an e55 but I would make sure and compare the valve lengths first especially if I were to use the 5.5L heads on any 4.3L motor. A machine shop could check this out for you. The thing is the amg heads are the same as the 5.0l heads but the 5.5l heads come with behive amg valve springs and bigger cams.
The 5.0l heads would benefit from using just the 5.5l cams and valve springs.

In this case the ECU would possibly need modifying and then again like in C43's that have done the swap, the AMG ECU that comes in the car should easily adjust. I believe the regular ECU's in the non AMG cars would naturally adjust also.

I am looking into something similar which is to put 430/43 heads on my 500 engine. The reason I would do this is to raise the compression from stock 10:1 to around 11:1 as run in the latter 55's.
I was on the phone with Kleeman yesterday talking about their cams in 430 heads on a 500 engine. They mentioned that 500 or 55 springs are fine with cams, but 430 springs are designed differently and will coil bind. I was told that if I use 430 heads I would need to swap my springs and retainers from the 500 engine. 500 heads and 55 heads seem to be the same expcet the 55 cams are better.
The potential problem with 43 or 430 heads on 55 is that the smaller comustion chambers (needs to be verified) might raise the compression on the 55 to high. I am going to get a set of 430 heads and cc them to see what effect on compression they would have on my engine.

C43 99 Kleemann Supercharged to c55 KL. S/C
I have c43 with Kleemann S/C and I am thinking to implant e55 amg w210 2000 engine into c43 and reinstall Kleemann S/C, everything should bolt right in. Yes or No?
I would use current wiring, houses and oil pan from c43.
1. Will I have to have reprogram Kleemann tuned C43 ECU to work with e55 engine, or it will adept?
2. Also fuel injectors are they the same on c43 and e55?
3. how about throttle body Inner Diameter and AFSensor are they the same?
4. I currently have complete stock exhaust if I implant 5.4L w210 amg engine into c43 can I use stock exhaust? ( iam planing to delete 2nd kats and resonator regardless of the engine swap and to install x-pipe as close as possible to the front of car and feed into Y-pipe just before where the muffler pipe connection is.
Have anyone done c43 into c55 with kleemann S/C
Any feedback would be appreciated?
I have a daily driver e55 AMG 2001 and it is fast but c55 S/C would keep me entertained
