Not to sound like an asshole, but in my opinion, your asking apples to oranges really.

Have you ever had a Bryant ?

I have used both, there really is a big difference in them !

 

Why not tell him the differences to help with his decision?

 

I love my Bryant.

 

I like my Bryant. You cant beat them.

 

Callies is ( assuming it is a top of the line model ) a very good forged crankshaft.

Bryant is a very good billet crankshaft.

A top grade billet crankshaft is made out of material generally considered to be far stronger than a comparable forged crank, hence they are the standard/only choice 3000-7000 hp.

F3 either would work fine, if you want the strongest then a Bryant is the way to go.

 

BRYANT

 

My Bryant crank was funny counter-weighted where a Callies (that I have seen) are not. The Bryant was also gun drilled though the mains where the Callies wasn't. There are a few other differences besides the material. Here's a pic of both of them side by side.

funny=fully as in center counter weights

 

Funny! Bryant is Billet! Callies are all Forged!

 

Wrong!!! Callies does center counter weighted billet cranks. For that matter Scat and a few more offers the same. Maybe that's what he was referring to. Apples to Apples kinda thing...

From what i've been told Winberg and Bryant are in a class of their own for custom billets. We went with Bryant because they had a better rep for on time delivery.We've run Crower forged and Chinese in a 2500hp BBC and the Bryant makes the nicest looking bearings by far. The Crower cracked under abuse and the Chi deal broke for no reason.
The Bryant is a work of art accurate to .0005 as close as I could measure,and they send a xmas card every year.
I know the difference between forged and billet and i'd never run forged in a max effort deal again. I don't think they stay as straight under high loads.

Bryant IS in a class by themselves in my opinion!! I split #3 and #4 main caps in two last year with nitrous, didnt even rock a bearing! Polished it after checking it out very thoroughly and have been running it all this season with ZERO issues! Best crankshaft made!!!

 

If you are looking for the best crank money can buy for your application it is a Bryant.

 

Can't argue with a bryant for the ultimate crankshaft, and ultimate in flexibility in design.

'Good' Forgings can take the power also, IF.... that's a big IF you can find a forging to fit your critieria, or requirements.

Such as, Center Counterweights. If your combination really needs center counterweights, you may not find it in a forging... in that instance, the Billet crank is far superior.

The forgings just limit you in design. But they are very strong.

The billets you can design one off strength into the finished product.

Neither is indestructible both can crack and fatigue.

Callies offers the best in a forging IMHO.

 

Correct. Now for the choice...........

 

Has anybody ever run a kings crankshaft?

Thanks guys for all the input, I heard a lot of great things about both cranks. My concern was billet vs forged in my application. I want to make upwards of 2200 horsepower withthe F3 and some where along the line someone said forged will last longer than billet in the over a long term use. The other thing was is the $500 more worth it? I think I have my answer. IF I was building a NA motor or even a smaller blower application I would be right on the cost savings with Callies but in this case i think I am going with Bryant. Now my only obstacle left is whether JE can make me an inverted dome piston for a 6.700 rod that can give me 8.5:1 using a 118cc head.

I don't think JE will have a problem with that. Do you have someone that can get you some good prices? It sounds like you are building one serious motor, good luck with your build.

 

Would need more info on your combo, but 4 3/8 stroke and reasonable piston/rod weight, I'd think the Callies would give excellent service.

Obviously, the Bryant is a pro level piece.

 

Combo BBC DART BIG M Tall Deck
4.50 stroke, 6.700 Oliver MX Rod, 4.560 Bore, 588ci, trying for 8.5:1 compression with Dart 360 118cc conventional head

 

I have a Callies in my engine and I do OK for power .

Check the BME site for the billet vs forged debate.

 

Call Bryant yourself. Get your pistons and rods first and figure out your Bob weight so the crank is made specifically to your combo. You buy a Bryant or any crank for that matter off the shelf and it is going to be a compromise.

 

I thought chevy was the best stuff every produced?... you mean all these chevy guys are wrong?

 

Callies makes a very nice "Manufactured" crank. Like others said Bryant vs Callies is like apples to watermelons. Bryant is a custom "one off" house where Callies is a manufacturer.

On that note I'm very happy with my Callies.

 

It's important to center counter weight when the stroke gets large. Not all Callies are center counterweighted, some of the large strokes that I have purchased are center counter weighted.

 

Crankshaft specialty ......You said that problem

 

A friend of mine sells speed parts but I figure "custom" pistons from JE arent going to have much of a discount. I dont really want to go that route but JE's inverted dome piston is for a 6.535 rod, which is ok but I dont want to cut the crank to clear the stroke, so I figured if they can make a piston with enough meat on the top and still have a -28cc inverted dome all will be good.

 

steve morris uses callies all the time and has good luck with exactly what you are doing with your combo. with that being said, bryant is better

 

Bryant is one of the best but also costs more than Callies. I ran Callies for years in a 555 with no issues. Used a Callies in new 598. We looked a Bryant but the cost was about double and Callies would work well for our setup. If you have the extra money or you were using any additives, turbo or blown I would use Bryant.
