I have gone to a smith Brothers 5/16ths pushrod against all conventional wisdom and guess what??

Its the mopar world on the no go 5/16, 3/8 or its WRONG, the chevy guys have done it forever, smiths 5/16x.116 have worked flawlessly in everything and if you notice it seems they make alot of the middle of the road heads to use 5/16 rods.
