callies all the way..ive never had there compstar but ive had there magnums and magnums xl and the work is next to none unless you want to get up there an pay 3k for just a crank
i havent heard much about anyone having to have work done to there callies stuff..scat aint as bad as eagle because they do all there finsh work here but i would def take callies over scat any day..

i would say it depends on your end result. if your going to put stupid power to it then go with callies. if your building a mid power street machine might as well save a little bit of cash and go with scat. but since its only a $200 difference you might as well get callies

We use and sell both the compstar and scat. The compstar has a nicer finish and more attention to details on the rods. The compstar comes with arp2000 bolts in the rods standard or you can upgrade the scat to that bolt for around $100. The other biggest differance is that the Scat crank is internal front external rear, and the compstar is internal on both ends. Both setups are very strong.

Both eagle and scat are overseas castings. ALL cranks should be inspected by a machinist and balanced before being used....there is no such thing are a "pre balanced" crank since every complete rotating assembly is different.
FWIW Eagle is rated to more HP then Scat. Both are good to well over 1,000 hp though and will be fine in 99% of LT1 builds when properly installed. Either or is a preference.
Both cast cranks are garbage, and should be avoided like the plague. IIRC Eagle SBC cast is only 500fwhp, Scat 450. That is right around where most properly made H/C stroker builds end up.
I voted Compstar.

Scat and Eagle should be used as paper weights. They are pretty much the only 2 companies I have really heard with failing parts. I know people build motors on a budget and they tend to be the cheaper route but sometimes you ll pay later on.
Now there are plenty of people who have good luck with their stuff but I would spend a few more bucks and sleep a little better a night.
just my 02 tho...

Forged scat or eagle cranks on the other hand are more then strong enough for any LT build on this site except for maybe a small handful of people...and those are the same ones who end up with core shift and block problems from the amount of power they are making.
I made this same decision a few months ago. I went with Callies crank and Compstar rods. I've never used Scat stuff and was seriously considering them but after seeing the product from Callies I'm conifident I made a good decision. I voted Compstar.
I got my setup from Corey. I havent finished the car yet. But Im Confident he does good work. I went compstar for my build. I figured if I was that deep in it then why not spend the couple hundred.
