I need a 350 chevy in my mercedes benz

what adapters do I need? Where do I get them? I have been searching and searching.

why? heavier, lower revving, older deign, and makes less power?

a 280 L6 carbed benz can easilly be punched to around 250 HP, and a 6.3/6.9 Benz V8 ( OHC MPFI) is round about 400 HP. you can get either engine, used for $500-$1000 USD - just shop around online, or with mercedes user groups

Well, you "can" do it. But you will be making everything custom. It isn't like there is a kit you can buy for the swap. I now Dan Johnson dropped a 350 into his rock mog, but there was a ton of custom work to get it done.

A reason to run a 350.....you can buy every part for the engine at any NAPA.

yah - but the reason to stay benz...you NEED to buy parts for the chev 350 [img]images/graemlins/smile.gif[/img]

try the vendor I gave here a while back ( rusty@mbz.org) for good prices on tune up parts. I paid under $100 US for the kit to redo my 240D - including new hardened valve seats, head gasket, timing chain,manifold gasket, et al......how much does it cost to do a full overhaul on a the chev?

hmm - forgot to mention, the reason theres no 'adapters' is that the 4/6 cylinder trannies wont handle a V8. in benz terminology, the 4's/6's use either a K4A 025, or K4C 025 transmission..the '025' part means they're rated to 250 ft/lbs input torque.

the rear ends are also kind-of steep gearing for a V8 ( standard 4/6 cylinder ratios are 3.9:1, and 4.08:1). a 350 with 700R4 is just about the only way to get a V8 in, and geared correctly, and even then, you'd kill the handling ( unless you're planning on using a corvette aluminum block 350)

FWIW, I've heard of 2 conversions to N.American V8's ( one a chev 350, one a ford 302)...both owners hated the results, and sold their cars within 6 months of completing the swaps

Thanks for the replies. I thought I would mention I already have a mercedes 350 v8 in it. Its raggidy and to rebuild it would cost around 6000 + to rebuild it.

uhh - mercedes never made a '350'... closest engine I know of would be the 560 SE/SEL/SEC motors. hows about we start from scratch here, and you tell us what model, year, and engine Mercedes you have ( and what transmission, if you happen to know). if you do the work yourself, even a 6.9 OHC V8 wont cost you $5000 to rebuild...and the Benz motors will beat the crap out of anything short of a tpi corvette motor in the power department!

also, can you be more specific in just how the motors 'raggity'...I've got a lot of Benz experience, w/ gas, and diesel engines, so depending on just whats up, i might be able to get you going for considerably less.. Just as a couple of examples: some older benze used a pair of points in the lower distributor body to conrtol the FI pulse timing..if they're pitted, or shot, the fuel mix sucks. ditto for coils & wires - many benzes CANNOT use conventional plug wires, as it screws up their ignition resistance... the 'correct' wires are expensive, and hard to get, but a Volvo coil + conventional resister wires are a cheap, and 100% effective solution........hit me with the details, and I'll see what I can come up with

I would stay with the benz motor over a chevy V8.

How long have you owned this Mog? year? photos?

Thanks
