Re: z28 1969 pushrods, what to use?
We have had bad luck with the swedged tip and ball tip push rods in 302 engines. On at least two dyno tests, they have bent or broke over 6000 rpm.
I have had great success with Comp Cams push rods. They cost more but are one piece seamless and made in the USA. .065" wall and good over 8000 rpm. This is what I use in my Stock Eliminator engines and none have ever failed. Many of the less expensive push rods are made in Taiwan. Just some food for thought.
