I paid for 3/8x.120 wall ball and cup and when one of them broke in half on the dyno testing, it broke due to a defect in the material I was told by Piere that they where .083 wall, not the .120 wall I ordered and paid him for
When the bad one broke at around 5200 RPM on the engine dyno it took out the one beside it and the upper half ended up gouging the cam lobe and lifter bushing after the Crower solid roller lifter was spit out, which cause the link bar to break the top of that set of lifters off
They replace the two bad pushrods but did not offer to help fix the cam and replace the pair of broken lifters
I ordered a set of Manton .120 wall and put the motor back on the dyno with the Smith Bros. and made three pulls and then switch the pushrods to the Manton set with no other changes, those pushrods made 8 HP more and raised the peak HP RPM by 300 RPM
This forum is for all of us to try and help each other, I hope this does that
