Crankchaft hp limit

Which crankshaft gives me the most value for money for a blown bbc combination with about 1600 hp, how much can a stok crank handle, I wonder if I'll run another year with the crank I have before I increase hp.

 

4340 forged worked for me at that power level.

I ran several Eagle and 1 Crower 4340 forged in several BBC at up to about 2,000HP with no failures. They were 8/71 and 14/71 540s on alcohol never above 8,900 RPM.

Buy a Bryant

 

If costs are not an issue then go with a billet ie Bryant,winberg,or valasco,but I personally think for a BBC at that hp,a callies crank is the way to go,we have have a callies in our blown alky BBC that has got over 400 passes on it and still going strong.

 

Is it ok with a Dragon Slayer or do I need a Magnum. The important is that it will not break if it weighs a little more is less important to me.

 

BBC cranks

have had good success with Eagle 4340's (4" stroke) at approx 1600BHP. Value for money in my mind

 

Dragon Slayer Worked for me.

Never a problem, now the motor is running in a monster truck, no problems.

 

I was told they are the same forging. The Mag has more mods,knife edging ect. We run the Mag 18-2000 no problems been running them for 10 years. Anything will break with detonation.

 

We ran a Lunati pro blower series in a roots blown alcohol dragster that ran 6.20s in the 1/4 and never had a failure though as mentioned if cost is no option a billet Winberg or Bryant is the way to go.

Best wishes,

Thanks for all the information.

 

Look at a SCAT for that HP. Billet is nice, but big $. My scat comes out and gets checked every winter.

 

Dragonslayer

Dragonslayer is great bang for the buck and it's A US forging.
