My machinist says he can get me a good deal on an Eagle BBC 4" stroke 4340 non twist crank for my new build. How do these pieces compare to a Scat, Callies and GM forgings?

I have had good luck with them . As always some one may disagree but My current engine has a 4.25" 4340 eagle crank and h-beam rods and have turned it over 8000 rpm often and have never had a problem. I just pulled it down to inspect everything and it all looked very good not even any signs of bearing wear or deformity.I guess it has alot to do with a good balance job and proper clearancing. buy the way lastweekend out I went a best of 6.34 @ 109.3 in the 1/8th
w/ a 1.381 60ft. time on 4 yr. old hoosier quick time pros. that are completly worn out. anyway I am very happy w/ all of the eagle products and will continue to use them.

Ron,
Thanks for the info.
Your Chevelle sounds like it hauls! High 9's :eek:

hello.my 4.00 4340 eagle did just fine.looked like new when i checked the 540.i think we will put a eagke 4.25 in ours 526.

Rons70ss...I can`t find your setup when I did a search.
Would you mind posting more info.
Very impressive sounding.

Epistuf..going against the grain here, but, eagle doesn`t seem to have as good a reputation or track record as does Scat.
Especially the cranks btw.
I`d go with a lightened, contoured Scat. Check Flatlander.com
Pretty decent priceing particularly on the kits, you can mix and match as you wish.

look in Kinzli's post on et streets most of it is there .
