im building a sbc 350 and i need some push rods. im running dart heads with guideplates so i need a hardened push rod with welded tips. i've been looking around and have seen many rods that have both of these but range in price from $25 to $125. whats the difference? i want good push rods but i don't want to sell my right arm for them. any suggestions?

thanks

You get what you pay for.

Beware of using the pushrods with the balls welded on the ends if you're running high rpm's and or high valve spring pressures. I've seen the welds fail and the ball come off. From there the lifter gets pushed out. Oil pressure goes away, then bearings, then everything you had in your wallet goes away. For the money I think the one-piece .08 wall pushrods made by Trick Flow and carried by Summit are a good deal. About $80. Manley, Comp Cams, and a few others are good as well but expect to pay over $100 for them.

A push rod is nothing more than the name implies, a rod. You can't do much to improve a rod...you can make it as light as possible and as strong as possible. However, those two qualities are usually inversely related....
Unless you are building some state of the art super motor...tubular chromolly push rods would be sufficient

I agree with engineczar get the one piece rod, I use Compcams, don't forget to check the rocker angle with the Dart heads, some of them like .100 longer rods for the correct geometry.

heh, and here I am about to use stock push rods. Well at least I will until I get new heads.
