I just got off the phone with Manton. They recommend 3/8 pushrod, but said I could get away with 11/32 .120 wall with the 400# open pressures. $12.35ea. Think i'll get the Mantons.
I agree. Most pushrod aren't stiff enough.
I went with the same deal as you are considering. I damn near bought 11/32-5/16 single taper pushrods but I'm getting ready to do W-2 heads so I said screw it.
That engine will get 3/8-7/16 double taper pushrods even tough it will be SFT.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
