any real world gains by switching to thicker/larger pushrods? I have .080 wall 3/8 and was thinking of going to .135 wall 3/8. B1MC heads with 350 seat and 920 open.
I switch pushrods on the dyno my bracket motor when it had the SR heads and T&D rockers arms on it. I had a set of Smith Bros 3/8x.083 that they custom made for the motor(I wanted thicker but they insisted that .083 was more than enough for 275 lbs and 680 lbs opened One of them broke in the middle during a dyno pull   ) that I ended up replacing (after I fixed the motor) during another dyno session. I switch from the .083x3/8 Smiths to a set of .120 wallx3/8 diameter sereis 3 Mantons with no other changes, the motor made 8 HP more and the peak HP RPM went up 300 RPM   I know there is more HP and valve train benifits in better pushrods than most people think  BTW, you might want to try a set of 7/16 x.095 if they will fit
