 Topic: 426 stock rods
Posted: 04 Mar 2013 at 6:54pm |
Stock 426 rods do not like high boost psi plus water a couple more hooks and block would have had some ventilation holes A-C bought them not me, yeah even though they had one of the largest in house foundries in the world they still looked at outside companies to help cut costs

Unfortunately none of allis rods do well without being flame hardened to a harder rockwell and then when they fail they break and that usually gets the block. These after market slimline rods mass produced out of someones cnc machine if there not about 450 a piece. BE learey of them. If the material is hard enough then the machine time is great and everyone charges for machine time.some rockwell testing has been done on a prominant aftermarket rod and rocker manufacturer and his 4340 hardness was averaging 20. As one poster on the rod debate said 4340 comes in billet stock in about 15 different hardness. Do you know the hardness the rod manufacturer is purchasing and are you willng to just take his word for it.

Are you refering to a prominent rod and rocker manufacturer for the antique tractor pulling arena? Small engine? Automotive?

Panky code meaning he has no idea what the hell he's doing so he needs to buy someone elses parts to figure it out and then trash whoever he bought from when he can't replicate what has been done.

i do not believe 4340 material can be annealed to a level of rockwell "C" scale of 20. industry standards consider 24 to be lowest attainable

Thus the reason I was asking for proof from our village idiot. He's lucky he picked 20 out of thin air. He could have sounded slightly more intelligent had he mentioned the scale, HRB, HRC, etc.
Next time rember to cite your sources, provide proof and give a unit of measurement pankey.

oh wow 24 makes it just fine for a connecting rod . Not a chance. china import metals arent worried with industry standards and your point is? 90,000psi yeild strength 4340 has a rockwell c of 18

http://www.interlloy.com.au/data_sheets/high_tensile_steels/4340.htmlThere ya go hillbilly, get an education. Did anyone say Rockwell 24C was being used for connecting rods? Cranky was saying 24c is the lowest you will see 4340 on the Rockwell C scale you dope.

You're a total idiot. Why does eagle, scat, and summit all supply performance rods made out of 4340?? Please tell us they are doing it all wrong.

well their 4340 intermediate performance rods check in the 30s for hardness and the $1000.00 and up higher performance level 4340 rods have no lower than a 41c hardness. Idiots dont compare to know the difference . They think one and all is the same . as stated in a rod rebutile they are about 15 different hardness of 4340. This is why their rods are sugested and limited to hp output . Really it should be rpms but In most car application hp goes up with rpms .
