I would agree, yes the scat/eagle/ etc.. stuff is maybe a touch off in terms of absolute perfection in metalurgy, etc. However, if its all properly balanced, clearanced, and assembled preoperly with attention to detail there is no reason it won't be capable of everything you can throw at it.
Last year I had major issues with my stuff all because of 3 different guys errors in assembly. and it was the best you can get, carrillo rods, crower lightweight crank, je pistons, etc.. when done wrong it all blows apart at the same rate. by the time it was over I had nothing and was broke, I buy a low budget, stage 2 shortblock from schwanke that is assembled and balanced proper.. I proceed to spin it 7800 to 8100 for 8 races in a sprint car, last race I spun it 8400 and it never even flinched. I stuffed new main bearings in it over the winter and have ran it twice , 0 problems so far. Maybe I am lucky, maybe not, all I know is the stuff I have is good, scat crank, eagle rods, SRP pistons.. old '78 chevy 4-bolt block... still kickin and grinnin..

CAT parts are pretty much junk. I'd gotten a set of 5140 rods 'cause they were so cheap. Curiosity really. When I saw them, they went on the shelf and I bought a set of Eagle SIR's.

Side by side, the CAT's look like rough forgings compared to the Eagle's. The surface was very porous on the CAT's. The shop that did my balance work said he's yet to see a CAT rod come in that didn't need resized. He's also yet to see an Eagle rod that needed to be resized.

Good luck!!!

I've used quite a few Eagle rods and the only problem I've run into is the small ends have need to be opened up a little, but better to small than too large! The good thing about using cheap parts is you don't assume they are perfect and you check EVERYTHING! Mistakes are made on the big dollar stuff too, and many builders don't pre check them because they assume they must be right, they are expensive!

I agree with Mavrik82 %100, there are so many "throw together" engine builders out there that wont check parts cheap or high $

you would be suprised what you might find, I find stuff wrong with new parts all the time, I dont care who makes it....check it!
