C43 swap to n/a 5.0 M113?
Hey gents
Was hoping some of you could clear something up for me.
My 99 C43 is about to cross the 300,000 mile mark, (big time timing chain rattle, oil leaks, but still runs very strong) and I'm getting ideas for possible engine swaps. I have two C43's, and one of them is getting the normal 5.4 AMG M113 swap at some point but those engines are getting hard to find.
I was browsing craigslist and a guy has had a w220 S500 engine with 129k on it for $400 for some time now:
http://nashville.craigslist.org/pts/4674956544.html
I already know I can direct swap it into my C43 and it would be plug n play, for the most part.
My question is this. There's no replacement for displacement, but the 5.0 puts out almost the same power as my stock 4.3. We know the only difference in the AMG 4.3 is that AMG tweaked the heads and cams.
Can I put my 4.3 heads and cams onto the 5.0? Presumably I'd see about the same power increase as from a stock 4.3 to an AMG 4.3 (about 30 hp).
Of course, if I did this, I'd get them sent to the machine shop for cleaning and stuff. I could also look into better cams, too. There are multiple opportunities here.
Anyone got any info for me? Getting the wife a GLK 350 next year, so that's when I want to tear down my 99 and start driving my 98 (black one).

Price of this Engine is great, is it running good, hope seller offers a warranty as well,
I believe our friend's "silence" is the only one who got 5.0l with HPS S/C, he knows every bolt of this Engine & can give more actual info..
i don't think 5.0l is a good choice compared to 5.4l, unless if supercharged it..
$400 is sooooo tempting..
ZAYED,,

Was just browsing Kleemann options for the N/A 5.0:
Kleemann headers, downpipes, cams, and ECU tune would bump it from 302hp to 380hp, with 385 ft lbs of torque.
Holy jeez.
Or should I save $400 and get same upgrades for the 4.3 after I tear it down and freshen it up?

300 miles is getting up there man, I would be tempted to replace the engine rather than refresh, if done by the book a refresh is very expensive, more cost effective to to get a low miles M113! 
..Just put 5.4 in both your 202 =)

I found out the increased displacement in the 5.0 is due to increased bore but not increased stroke. Strongly implying my 4.3 heads would work fine. But still more info is needed.
Either way I would do a lifter and valve job before anything went back in the car. I need to get the timing chain rattle sorted. New tensioner did nothing for it.
Fun fact, the timing chain tensioner from the c43 is the same one from the McLaren SLR.

I am sure the heads will work, but I would doubt they would gain any power, likely lose. Also the main difference with the 43 bump was the intake manifold and cams, I dont even know if there was any change in the heads at all. I would not mix and match these parts, you will very likely lose, you need more volume for more displacement and i am sure the 500 heads are as big or bigger than the 43 heads. plus they are newer so they have received any design improvement. the 500 might be rated same hp, but the torque is much much more and the car will be alot faster with a stock 500.
Also for the added cost of getting the heads worked on, you could just get a 55 engine.

All M113's using same intake manifolds, no difference,,
C43 using a unique different cams than CLK430/E430, anyone knows what a special thing about C43 cams..?!?

I'm sure the cams have higher lift or more duration. The power comes noticeably higher than the 430.

+1,
AMG created those manifolds in 4/1998 & put them in all M113's 5.0l/5.4l, for that MB made those manifolds productions & stamped as (AMG idea)..

C43 heads where probably flowed or modified by AMG together with the different cams.

I'd be careful with that feature. That just means that yes the same manifold is now available for all. It doesn't mean that is what was OE to the vehicle. Parts get superceded all the time.

There is a few superseded manifolds, I assume that if all update to the same number that they all once had the similar manifold? are you saying I should search on OE part numbers to be more accurate?.
