Eagle Crank in 650 hp sbc. Broke the front cheek at the 7/8 and came out the back of a SHP engine.

[/QUOTE]

I had good luck with Eagle cranks and rods in one of my own BB engines.....

You obviously did not

I have seen posts of a broken Callies Magnum 4340 BB crank with very low runs

Oliver rods also....

I never saw any failures...

Rod bolts?? whats that lol Called improper yield and stretch. > Cycles.... Too many will get ya most of the time.


A racing buddy posted pictures of his 632 I think it was with holes in the pan

A motor he bought used... and he said a ROD BOLT broke

The next set of pictures he posted showed a blackened rod and crank and a twisted broken in 2 Oliver rod....

I responded by telling him straight out a rod/crank that's black spun a bearing first and then stuff broke.....heat does bad things to metal.....LOL!

Oliver BBC rods plus 250 runs equals Kaboom and it is not the rod bolts at least not directly! Their design includes a very short rod bolt to gain clearance at the expense of the strength of the rod cap! Take a look at their BBC cap and say a Callies and you will understand!

There's not a rod out there that will withstand a spun bearing failure for long! The crank wins that battle 9 time out of 10!!!! LOL

Exactly My point Al but for some reason many people don’t recognize the obvious.

It is hard to tell where things are made now and stuff made in China is getting better every day. Like it or not.

Bryant is out of American forgings, as is Molnar and Winberg. Their American steel units are the billet only. Crower has a few forgings left..
Bryant tried to buy the forge tooling from GM, but it was scrapped instead.
Speaking of regular SBC stuff only, this is what my shopping has revealed.

Correct, at the least, foreign sourced materials.
There are NO American steel FORGED SBC crankshaft raw forgings being produced. Probably never again. It would seem that they were all from the GM forging plant for many years.

America has lost the ability to build many things, Computers, cameras, Tv's, much of our machining and forging, and once it is gone it is hard to get back.

Nothing that a war with China can’t fix and reboot our supremacy but the swamp in Washington is afraid of China and more to the point afraid of the backlash from corporate America who they work for and rely on their $ to stay in power and then there’s the dumb Americans that don’t care about anything but the price with no concern for where their $ really goes and thats to build china’s military and economic strength. It’s not if but when they will be the #1 super power in the world but don’t worry those here responsible for funding china’s war machine will be dead when it happens so they’ll never get to see what they are responsible for, they’ll leave that to their children and grandkids.

What are you building? Callie’s crank and rods would be just fine in most applications. I believe one of the nicest cranks on the market is probably Bryant, but most have no reason to spend that money

I agree Curly.

That Eagle 3.480 crank was from 2012 with less than 250 runs and the engine builder I used said it magnafluxed good and to use it in a new SHP engine @650 hp tops. It failed in less than 150 runs.

I switched engine builders and they recommended Compstar crank / rods that are in both of my engines at 700 hp. My first engine was rebuilt at 500 runs (spare now) and my present (both Darts) has over 600 runs leaving it in until 1000 runs.

That is correct. I called Callies 2015 prior to purchasing from engine builder. Callies said Compstar was their forgings from China, inspected and machine finished in USA and acceptable at 700 HP. So far I find the quality to be correct based on what the engine builder said of first engine rebuild and service to date of second.

Nice! I think that's pushing the limits, how many runs on the bottom end?
