I have heard that the factory pushrods are shorter than 7.4, and I have heard that the aftermarket hardened 7.4's are a little longer. I was wondering if anyone knows what the ACTUAL length of the hardened 7.4 pushrods are. I pulled the stockers out and I am going to set them up tomorrow with a height gauge and measure the stock length and see what kind of difference there is between 8 of them. did a crude measurement with a set of calipers and came up with 7.385 for the stockers.

 

I measured 8 Stock pushrods and came up with them being 7.3945-7.3956 so they are really close to the 7.4" everyone says they are. I wanted to let you know because I have searched for the last couple days and evetyone thinks they are 7.380 or so, but I still wanna know what the hardened lengths are. I measured the wall thickness of one and it was around .077".
