I have ran a Howard's hydraulic roller on the street for over 5000 miles and lots of dragstrip use in the last couple of years. I never rev the engine over 6,500 so it works perfect for me. Very happy with its performance.

A friend was having problems with Comp hydraulic roller lifters. He replaced them with the same ones that I use from Howard's and the problems all went away.

I'd also recommend the Howards fuel pump push rod and the crane 66970 - 1 coated gear to go with it. Both seem to be holding up really well!
