View Full Version : Scat Crankshaft
Codi Apr 13th, 01, 08:17 AM I need a new crank for my BB 454. I am thinking of either the Eagle cast steel or the SCAT cast steel cranks. Has anyone used either one or heard anything about either one. Any input would be appreciated. I would like a stronger one, but my wallet and wife won't tolerate much more than the cast steel.
6-71BlownCamaro Apr 13th, 01, 11:52 AM Just to let you know PAW (performance automotive warehouse) sells a forged steel crankshaft for $599.00
It is a brand new crank includes cross drilled main journals and wide .125 radii for increaced strength. 4.000" stroke standard journal sizes and two piece rear main seal.
This crank will need bearings #M77CB743H and
#M77MS829H.
Good crank and great price what more can I say.
(818)678-3000 is their Phone#
Sure beats paying that same price for a cast crank IMO.

oger Apr 14th, 01, 01:11 AM Have you tried looking for a stock cast one. They aren't that bad and will hold up just fine if you don't try to run 7000RPM with it. The last one I bought from CHEV was steel cross drilled {and if you can get a deal} was about $750.00. It was over a year ago so I don't know about price increases.
ilbl8 Apr 14th, 01, 10:59 PM watch out on the cheep crank's they are from china and the quality is not that good. i have nothing agenst china, just the quality of most of there part's is IMHO crappy compaired to other maker's. they are good enginer's but there casting and forging ability need's a bit more work. so dose there metalurgy.
rember you get what you pay for! i would get a US made crank or one form a company with a good rep, that will stand behind there product. you will probably be more pleased with what you get in the long run. all so i have heard of some bad stories about PAW, i have never got a part from them. so this is just water cooler talk. they do have some nice prices tho. but they charge for there catalog so i am a little leary of them. i mean hey if they want your biz they can give you a catalog. heck there web site has no online catalog, i guess i am spoiled by summit and jeg's.
i like scat crank's. i have alot of frind's the say they are the best for the money. i have only used OEM stuff myself.

6-71BlownCamaro Apr 15th, 01, 08:07 AM Just to say a something about the PAW crank I mentioned...
I have seen that very crank in a 454 with a 250 shot of nitrous! the car runs low 6 sec passes in the 1/8 mile.
I dont know where this made in China stuff got started:P
Where did you hear it was made in china?
boodlefoof Apr 15th, 01, 03:49 PM According to Scat's website (an article on it) their cranks are made in house in their California plant.
ilbl8 Apr 15th, 01, 07:57 PM 6-71,
it is a very well known fact, that most cheap cast or forged part's are made over sea's. china is the # 1 exporter of this stuff. all you need to do is check this board. this has been covered in the past.
just because one crank held up is not a way to say all will. i have seen some chinese crank's hold up fine in race car's and other's break, over and over till they get a good one or buy an american made one.
scat dose not cast or forge all there crank's in house. some of there cheep one's are machiened fron imported blank's or rough fordging's/casting's. this is a fact. call them and they will tell you this. they have too it is the law.
you know like a part box say's "made in canada of U.S and Canadian part's" they have to tell you where stuff come's from and where final assembly or machiening happen's.
also see this thread. it suport's what i am saying. http://www.camaros.net/forum/Forum9/HTML/001268.html

Codi Apr 16th, 01, 07:44 AM 6-71, and ilb18...
Thanks for the reply. I will have to stick with the cast steel. Jeg's Eagle is $335, Northern Parts SCAT is $229. If I could go the $600 to $800, I would. To boodlefoof, I read the same at SCAT's site. I like what I read. All American. As for imported stuff, some is good, some is not so good. I try to buy local first, then American, then what ever else I can find. PAW has a history of providing quality parts at a good price. I've used their stuff on other projects with great success. I like PAW. You just need to know your parts and watch the brand names. As for stuff made in China? They still got my da%& plane. Thanks for all the input.
Mark W. Winning Apr 16th, 01, 09:44 AM Most of the makers will outsource (read: CHINA) some of their low end stuff. Order what you want, if the box or crank are stamped "Made in China", return it.

pdq67 Apr 17th, 01, 11:32 AM My 2 cents worth. Thought I saw an add for .060" undersized BB bearings once so maybe the cast stock BB crank is stronger then alotta people think that it is???
My point is that maybe you can save a crank by going .060 under and not have to buy a cheap foriegn part!!!
Codi Apr 18th, 01, 07:20 AM My machine shop has always said a crank doesn't care how far it is turned down. I know of several running .040, .050. and .060 under and they seem to survive. My original crank is FUBAR. Not only are all the journals toast, it is bent .040. Dave the machine wizard says it will probably break trying to straighten it, so here I am. I will probably go with the SCAT crank. I liked what I read on their site and a cast steel crank is about all I can afford right now. Thanks for all the responses.
chacane67 Apr 18th, 01, 01:31 PM A-lot of the left handers locally, use SCAT cast cranks with excellent results.
I personally have used one of SCAT's cast cranks in a s/b application and spun it 7500 rpm and beat the heck out of it regularly....it put up with all of my abuse.
One thing to mention....DO NOT put a Fluidamper on the end of it. The metalurgist at SCAT (with the reports from many racers nation wide) has determined that the cause of many crank snouts breaking was due to the weight and harmonics of the Fluidamper itself.
I have really heard nothing but GOOD reports about their products....
