There was someone posting about this in the past couple of weeks and I don't recall where. They cited Harland Sharp saying the difference is significant.

My comment to that is Harland Sharp has a vested interest in promoting that difference to sell their product just as much as Crane and Comp have a vested interest in down playing the differnece to sell their product.

I have enough confidence in Crane or Comp that they would not suggest that you use a Chevy rocker if it was significant enough in the long run to make a difference. Likely the difference is you will wear out the guides in 150,000 miles with Chevey rockers verse 200,000 with Harland Sharp.

I would put this issue in the same category as the superiority of the cams designed to take advantage of the larger mopar lifter diameter. In theory it's true but in practical application it's not significant.
