I am pretty sure that I need to replace the balancer on the car (starting to wobble) and my question is- what imbalance should I use? I've seen 28 Oz, 50 Oz, and internal balance (0 OZ imbalance). So for a stock bottom end, what do I order? I am also looking to do a fluid balancer as well to get rid of the rubber hub.

you must first verify is your engine internal or external balance.

Internal or External
With “internally balanced” engines, the counterweights themselves handle the job of offsetting the reciprocating mass of the pistons and rods. “Externally balanced” engines, on the other hand, have additional counterweights on the flywheel and/or harmonic damper to assist the crankshaft in maintaining balance. Some engines have to be externally balanced because there isn’t enough clearance inside the crankcase to handle counterweights of sufficient size to balance the engine. This is true of engines with longer strokes and/or large displacements.

I believe your engine is internally balanced. You can verify this by locating your current damper and checking for counterweights. This should appear to be what looks like a half-mooned shape on the damper if it is externally balanced with counterweights. If not it is internally balanced.

I happen to work for Fluidampr if you are going to go with a viscous style damper. Fluidampr is part of our sister company Vibratech TVD who invented the original "fluid filled damper" in 1946. Go to our website for more information. Just type Fluidampr in the google bar.

Check but I think a '94 5.0 is 50oz balance.......

1994 5.0=50oz

i appologize 1994 5.0=50oz. i was thinking externally and typed internally. You need fluidampr part # 650221 50oz. 34oz. counterweight on damper and 160z. counterweight on flywheel = 50oz.

Fluidampr 100% made in the USA! Dont be fooled by cheap chinese imitation.

Thank all of you for your replies- I am likely going with a fluid damper as I dont want the rubber separation to occur again.

you can get plenty of cheaper balancers sfi approved and made to not slip or sling the rubber out!

5.0L are 50oz imbalance
strokers are 28oz 331/347 cu in ( there are options for 0 imbalance blah blah blah) depends one what you balcance for during the build!
and are 351w 28oz
