I would recommend a Callies Magnum with the BBC nose.

http://www.callies.com/crankshafts/magnum/magnum-small-block-chevy/

Putting one of these in mine right now after breaking the nose off my other 4340 crank. Been running the ATIs BBC diameter hub on my SBC double keyed.

When it broke it took out all the valves in both heads.
If you can't afford to keep rebuilding then do it right the first time and spend a little more money and have the piece of mind knowing it will never be an issue again with room to grow.

Every major, long established, crankshaft Mfg now seems to have several grades of crankshafts. I am not a metalurgist but I don't think anyone can offer a great crankshaft for less than half the price of their top line crank. I would think long before I used a lower cost crank on a high power boosted motor I planned to run hard.

Ok guys.

The Cola crank in question is a quality piece (1000hp?) depends on application. 1000hp in the quarter mile is a lot different than 500hp for 200 miles none stop weekend after weekend!

This crank shaft listed was and still is a NASCAR approved crankshaft, used by sportsman series racing. (mostly the modified series)
The 3.50 stroke gives a 4.030 bore a 357.16 cu for the NASCAR 358cu limit.

They are allowed to lighten the crank to a limit of 45lbs. (about a 3 pound removal) crank averages 48lbs.

The low price is a product of volume usage.
Outside of NASCAR a 3.48/3.50 crank is almost obsolete with affordable stroker cranks available purchased by the masses.


=====================================================

You will also find there is only a few casting company's for crankshafts, (China casting is not counted :no:)

The number 1 casting plant for USA forged steel cranks is Signcast in Wisconsin.

Cadillac Casting Company in Mi is a major source for cast crankshafts & just about anything of Ductile iron for automotive made in USA.

And the number one source is Darcast in United Kingdom, they are also a major axle supplier.
These company's are raw casting plants, not machine company's.

The machining process is done by many many different company's around the world.

I do know Lunati & Callie's do in house machining of raw castings. (I can not speak of others) they may only machine the high quality cranks and have a second econo line done outside.

Cola and Callie's both have supplied crankshafts to GM for GMPP engines. If you have a GMPP engine with a forged steel crank the odds are you have a Callie's crankshaft.

All GMPP 383 engines with a 3.80 stroke forged steel crankshaft it came from Callie's. FYI

==================================================

Also MADE IN USA has some limits, a raw part can be cast "ANYWHERE" and considered raw material for a part machined in the USA.

America is still the number one source for exact high quality machine work! It just cost more.

The EPA & Government regulation has run off most all USA casting company's.

And made it imposable for a USA casting company to compete in today's world market.

Do NOT look at the price tag of this crank. When it was manufactured, it was a TOP SHELF crankshaft, probably double+ the price you see today.

From what I read, Cola went away several years ago, (2006-2007?) consider this like NOS discounted. There was probably a huge inventory sold at pennys on the dollar.

Also I'm not going to buy this crank. It will be one with the same part number, I only posted the link as a refference.

Here's the deal, (it's a package) I'll be getting the crank included with a rotating assembly for $800. What I really want are the $2K Carrillo H beam rods that come in this deal.

I guess I could sell the crank (cheap) and buy a Dagonslayer or Magnun, but if the Cola will live at 1000hp , 1/4 mile at a time, I'll just have it double keyed and use it.

I do agree if I buy a new Callies it will have a BB snout just for added piece of mind. That said my current combo (383, F1 Procharger, 12 rib) has been together since 2004 with a Made in China crank and rods in a GM 010 block, appox 800hp, 7300rpm.

I am pretty sure my current junk has stayed together (excluding the broken Made in China damper, pic above) because I'm not running a cog belt.

What do you think?

Thanks to all that posted! I'm still thinking about weather to use the Cola???

BTW, one of my racing buddys has been using the same Cola in his 871 blown 357 SBC, w/ a cog belt, and he has detonated two of his engines to death. He melted pistons and bent rods, but the crank was fine.
Was he just lucky?

Slingblade, no I'm not running any kind of crank brace.

procharged67, you are correct as Howards and Callies cranks are the same. They say you order a Howards you are actually getting a Callies crank.

Real McCoy, your right on the money. You get what you pay for in quality.
i have been running the howards crank for 4 years .
1300 hp 20 lbs of boost no problems. hell i even run eagle H bean rods!

your spot on about cola being a quality part and comp having old stock. Cola, L.A., etc etc were good pieces from company's that are gone, I called about one of these last week but all they had left in 400 main was a 3.40 stroke.
