External balance forged crankshaft

[jpwalt1987]

Who is making a forged steel crank that can be externally balanced using the stock flywheel and harmonic balancer? My searches haven't turned up any info.
I need one for a local guy in town.

Aren't most aftermarket cranks able to be balanced internal or external? IIRC, internal is "easier" but either is possible. I could be wrong...

Get an internal balanced one and have the shop doing the work set it up as external balance. If you're set on an external crank check with Mike at fullthrottle.

Eagle used to make one. It honestly makes more sense to go with an internal balance set up although the cost is higher.

yep internal is the way to go imo

dan usta make stroker its but now he only builds them an doesn't sell kits

I talked to Mike at full throttle. All his in the rotating assemblies are internal balance. It's not for my car. That local guy I've been helping managed to lock up his motor somehow. Pulled the plugs out and it is super tight trying to turn with a tool on the flywheel. Didn't want him to have to buy a new flywheel and a BHJ balancer. Big money on top of what he's about to spend.

I agree that internal is the best way. I talked to DLS also. A complete long block is high dollar!! He built my motor a few years ago and I love it but this local doesnt want to spend that much.

I've got a couple of stock cranks if you want to go that way.

We have Eagle external balance cranks on the way, We also have the internal Eagle cranks. Special pricing now and the August sale is still going on check the vendor for sale section

Nice! I thought they stopped making external forged cranks a while ago. That's good news! I have one already but good news none the less!

 

[Mike Licht]

they did stop but are back at it these are new.

Jeremy... An internal crank with a properly machined stock balancer/inexpensive neutral balancer and a properly machined stock flywheel/inexpensive neutral flywheel is better than the external crank set-up you're inquiring about... And not much more $$$.

Why?

 

[750H.P.V6]

Some OEM engines including Buick V6's are externally balanced due to the fact that there is inadequate counterweight material on the crankshaft to allow for proper balance. When the engine is externally balanced both the flywheel and in our case the crank hub act as counterweights.

Where there is adequate counterweight material (ie: with a steel crank) internal balance is preferable in a H.P. application. The crank will run truer, be less apt to flex and bearing wear will be better. When the engine is internally balanced the flywheel and crank hub will be neutral balanced and therfore not add or subtract from the overall balance of the rotating assy. They can be replaced if necessary at a later date without having to re-balance anything.
