What crank would be more reliable for a 500 horsepower motor? Scat 4" or Manley 4".

i'll take a Manley anytime over a scat. We've made over 1000hp with a Manley ls1 crank. I use alot of their cranks, rods and pistons.

How come Atech Motorsports doesn't carry any Callies LS crankshafts???

Callies Performance

They can get them, I think its because they are a new vendor, may not have all of our parts lined up yet. -Adam @ Callies

How do I buy your products at Atech pricing? Do I call them with part numbers?

Callies Performance

You can Call them, I am not sure what they have them listed @ . A std. 4.000 LS is Part Number: APO31N-CS

I'd say callies/compstar.
But stock crankshafts in LS motors have seen 1000+ horsepower before...

I'm glad I posted this tread. Just got off the phone with Callies. Sounds like they're the way to go.

Compstar made by Callies are forged over seas and machined in the US.
BTW do not let "Made in China" through you off, reason stuff is garbage their is because the engineers in the US make them use cheaper metals to keep cost down. Example Piston 2618 alloy here is the same compound as in China.

I have a manley crank in mine. Cost as much as an eagle with the quality of callies, really cant beat it. Most cranks are forged over seas and machined here, just my .02. Not many foundaries left in the us.

^^^^^Correct, Compstar is our off-shore brand, we engineer it, it is manufactured over seas, and we finish it in house. Callies Magnum and DragonSlayer are 100% American (start to finish in Fostoria, OH). The forgings are from Bharat forge, located in Lansing Michigan.

Whats the hp rating for the compstar crank vs the magnum or DragonSlayer ?

BigRich954RR

iTrader: (1)

Well not sure but ive seen the magnum well over 2000hp. which is is pretty much the same as dragonslayer.

The few more dollars for the dragonslayer is well worth it. very nice crank plus resell value is alot more. (side note also helping keep jobs in US)
