[also posted on Tech Forum -- sorry, I'm not sure which is more appropriate]

Hello, all.
I need to increase the power available in my 6,200+ lb Gelaendewagen ('84 280GE, "double-cam"). It's only tuned to about 150 hp, but European (gray-market) cars have over 185 hp and more. I've decided to swap my low output (e.g., 8:1 compression ratio) engine (M110.994) with a remanufactured "long block" prepared as the higher output European car engine version (high compression pistons, hotter cam), such as the M110.996 (I think that's the number) as an example. However, I'd like to solicit input (viz., references, in effect) for selection of the shop from whom I'll procure the rebuilt, customized engine.

I've found three candidate outfits, each claiming years of experience on MB engines, quality work, and willingness to do the customizing:
1) NOEL's, of Winter Park, FL
2) METRIC Automotive Engines, of Canoga Park, CA.
3) EIS, of Portland, OR.

My question -- have any of you had any dealings with any of these companies, or heard anyone comment on their quality. If you prefer, please feel free to e-mail me privately/confidentially.

Thanks very much to all, in advance.
