(11-03-2014, 08:24 AM)74Dusted So I'm going to fabricate an OM617 to Small Block Mopar Adapter, I'll machine the flywheel to fit the OM617. The only thing I probably won't be able to handle is balancing the Mopar Flywheel to match the 617. I'll farm that job out to the performance shop that machined the crankshaft in my 6-71 Blown Duster. Unless the 617 is Neutral Balance/Internally Balanced, in which case I could use a 3.9L/273/318/340 Mopar Flywheel.

Anyone know if the 617 is Internally Balanced/Neutral Balance, or External Balance?

My 617 was neutral balanced.  I do recommend getting a HEAVY flywheel for this engine.  I ran a flywheel off a 616 (<20lbs, IIRC) for over a year and while it did seem a little peppier than with the heavier 300GD 617 flywheel(~30lbs), it also was much less comfortable to drive at lower speeds (a LOT of chatter and shudder off the line and in stop and go...you get used to it, but it never feels "right") and most off-road would have been even worse.
This engine likes a bit more counterweight / momentum to keep her running down low.

W123 Mods: 4 speed ** manual climate control ** '85 Kalitucky intake ** manual windows & full tint ** Euro headlights retrofit w/bixenon projectors ** 4 brake light mod ** Vogtland 50mm drop front & Lesjofors S600 drop rear springs ** 16" rims ** late w126 brake spindles, rotors & calipers ** full suspension rehab ** Bilstein HDs ** AL129X alternator & 1/0 starter and charging cables ** 300GD clutch/flywheel ** AFCO 80103N radiator & Earl's 41610 oil cooler ** custom block-off plate, remote oil filter & t-stat ** MW IP w/ tomnik's 6.5mm 'Holly' elements **

S124 Mods: 400E Rear subframe ** SL600 Brakes ** Late 300E 210mm diff ** SLK230 6 speed ** 17" CLK rims ** Vented RF Fender ** Facelift Hood, Headlights, and Lower Cladding **
