thanks i searched but dident get **** maybe i just suck at spelling

 

just china 4340 rods

 

so they are ok to boost with they dont tell ya any numbers like what it would hold thats what i was wondering

 

Tuner Toys,Spark,Scat,Eagle,Crower econo,Manley econo all the same rods.Some have different options for rod bolts but they are generally the same and more then likely roll from the same line at the factory in China.Good for moderate builds like 4-500 hp and reasonable rev limits like under 9ishK rpm

 

you cant assume that they all came out of the same factory.
If they were of similar quality in the forging, what will set them apart is the final finish of the machining.
Alot of these rods are purchased in raw form and finished possibly locally here in the US at their own plants.

While alot of these rods look alike, what differs are the machining done on the big and small end bores. You'll find that the better companies have much more consistent finish and clearances. Factors that can determine this would be the quality of the machines theyre using, experience and just plain old quality control.

From just glancing at them they can all look alike, but from experience in using these different brands, you'll see that there is much more inconsistencies in certain brands over the others.
