i bent 2. the guy i bought them from had sent me a set that had a couple bent ones also. changed to the cm ones no more bending.... go figure....

I sell Manley 1 pc hardened pushrods for our trucks for $99 set. Waller and many others have been using these pushrods in high HP builds for many years without any problems. FWIW, Manley makes most of the aftermarket pushrods for the likes of Comp, Crane, etc....

Michael,

When swapping pushrods do you just use the stock lengths or do you measure for new length after swapping heads to say L35s?


My plan is to run L35s with the 1.6 Crane golds, so i guess my question woudl be can I run the stock length>?

I'll give you a call to order the rest of the stuff I need to swap my heads here soon.

Stock length is 7.200", but you can go up or down safely .050 without much adjustment. L35s require no longer/shorter pushrod than stock, and there should be no need for a Louis tool or custom pushrods when using stockish GM iron heads AFAIK.

It's always a good idea to use a pushrod checker, but for what your doing (a proven and common swap), then I would just slap it together with stock length pushrods (I did). If something is way outta whack, then check for a collapsed lifter, misaligned rocker, etc....but you should have no problem.

guess someone outta mention, a little prussian blue on valve stem tip and you want to see the rocker makes contact in the middle 3rd.

if you see that the geometry should be correct.
