I was looking all through my summit magazine and can only find 5/16 7.2" pushrods. Will the 5/16 be strong enough for use with the 306 cc cam I just bought or should I try my hardest to find the 3/8? Also are those the correct length I need for a stock deck set of heads? The stock pushrods in there are only 10K miles old , will they be just fine? Are stock specs the 5/16 7.2"??? Thanks---

EDIT: I just found some comp cams 3/8, but it doesnt say the length, it just says "standard small block chevy".....uhhhh.....

 

You will be fine with 5/16 pushrods...

I have Trick Flow chromemoly 7.200 pushrods wth 0.8 wall thickness for sale...Part # is tfs-21407200...I paid $85 for them They are one of the hardest pushrods you can get...If you are interested email me at sebastianek23@hotmail.com

Thanks

You want the hardest, or the stiffest?

 

Are you trying to clue me into something, lol?! Are the t.flow ones good?! Thanks-

 

I"m attempting to determine whether the guy worded it that way intentionally, or if he doesn't know the difference between a hard (heat treated) or a stiff PR. A hard rod doesn't necessarily mean a stiff rod, AFAIC.

Yes, the PR needs to be heat treated to withstand contact with the guide plate, but in the end, I want the stiffest PR. The one with the least flex. No, not stating the rods are good OR bad.

 

Pushrods aren't always the most glamourous parts on a motor, but they sure can make a big difference. "cheap" pushrods I have found are that way for a reason, one reason why at minimum I suggest the Comp Hi-Tech 5/16 pushrods.

BTW if you want a 7.200" long 3/8 PR check out Smith Brothers or Manton, Comps 3/8 PR's only go as short as 7.500"

Thanks guys, I just bought the Trick Flow 7.2" 5/16th ones off the guy that posted in this thread. I am sure they will be good enough, I am not going too radical with the engine. I appreciate it---
