anyone have anything good to say about them??? i've heard they break easily and a lot of the times they dont do everything they say... building a 9:1 355 B mod motor... thinking on these rods but heard a lot of bad things about them. i have a set of x rods that need re done but heard its cheaper to buy them from jr or midwest...

I've built 2 claimer engines with JR rods and so far they are doing the job. Both engines are running with a 16" vacuum rule with a 350 3bbl carb so needless to say performance is limited with them. I'm not sure how those rods would hold up in an engine that did not have to pull vacuum nor run that small of a carb. The engines are turning around 6000 rpm max. Rod to bearing clearances were consistant and so were the rod weights. Both engines are balanced, which I feel is one of the most important aspect of any engine you can build. Both engines are less than a year old, but are raced every weekend. Hope this info helps.

after a talk with doug from PTM i am taking my x rods over there and having them re build them. he said they will do just fine. did gm ever make a 6 inch rod or was that an aftermarket deal that went on??

Oldsmobile used 6 inch rods but chevy never did.

chevy has been using stock 6 in rods for several years.

actually 5.98 something. gm powder rods.

if allowed you can buy new cast rods for 160. a set. from competition products they are prowler, cat etc, they are nice for the money and way better than any x rod.
