Both are about in the same range as to quality. Personally I'd go with the better price of the 2.

Yep, go with the best price. Both are stronger than stock...and oem cranks have survived 800 hp nitrous engines in the ls-1. So it is probably a safe bet that any decent forged crank will hold up to what you are going to throw at it.

The real concern if you plan on pushing a great deal of hp is: what rods are you using?

So you are shooting for what 600-700 hp on the bottle? You are not going to break either crank with that, if you change the oil regularly and don't try to spin it past 8000 rpm too often. You don't even need a steel crank for what you are doing. Stock rods, with a really good tune, if they are carefully looked over and everything is balance properly, will safely take 600 hp.

I used to shift a forged (oem) sbc crank in a 361 cid (.060 350) at 7500 rpm and had over 200 passes, and 20,000 street miles on the crank when I tore the car down. I reused the crank in a truck... when I wraped the truck around a pole the crank was still ok.

This was in a 10 second car, making just over 600 hp.

Yes, they are 2 diffrent motors. Not many people around here use SCAT. I've heard much more about the eagle parts than I ever have SCAT. Like everyone else said, just pick the one that is better priced since they are pretty much the same all the way around.

They are both good. I bought all Eagle 4 inch stroke stuff. Plan to turn it to 8500 some do soon. I would not think twice about putting that kind of power on either one. If you have great machinest that can balance everything right and fit everything right. I had all my stuff remachined and checked. Oh, I do not know if I would turn it 8500 in an aluminum block though. I went with the cast iron 6 litter block with steal main caps and arp stud kits. I am sure some one on here has tried to turn the stock 5.7 litter block tight. Maybe one of them will sound off here in a sec.

Yes, but I was using an example as a comparison. Just pointing out that crankshafts in general are capable of handling more abuse than most give them credit for. They are rarely a weak link in an engine.

There is no need for a rev kit. Strokers aren't intended to rev to the moon. IMO, as long as there are springs avalible to handle your cam in a desired RPM range, rev kits are a waste of money and HP. If you planned to rev past 7k, which you won't, one might be neccesary. There are to many good valve springs out there to worry about a rev kit in a hydraulic application.

nick the same thing i told you.. u can make 600+ on the stock bottom end and and a rev kit is pointless.. you have multibple people local trying to point you in the right direction.. just listen, do your research.. .. i let you make a decision on a part and you see what that got you.. LOL (you know what i'm referring to..) you know i won't let u **** up ur car.. u need to sit down with me and keith and we can see what ur goals are and what its gunna take to acheive them safely..
