Ok...This ought to stir the pot...

I learned about pushrods early, the first 360 I built with a roller cam. I had a set of 3/8 pushrods laying around that seemed to work pretty good with the Harland Sharp rockers. The first hard pass at the drag strip started popping at the top of first gear. Shut it off, towed back to the pits. Check it out and find the pushrods bent like pretzels. Had to remove the intake and break them to get them out of the heads
