roller cam and roller lifters/ hydraulic

Don't be afraid to spend money for quality.
Good anti pump up hydraulics get pricey. Hell , stock replacements aren't cheap.
Shop with an eye on the best you can afford , not how much you can save.
You aren't buying tennis shoes or dish soap.
Talk to Tim @ Bullet racing cams ( 662 ) 893 - 5670 and ask what he'd recommend.
They have a steadily growing reputation in the hydraulic roller world and they don't make lifters. Ask any cam grinder that doesn't have a horse in the lifter race which ones they like and why. Try a call or p.m. to an engine builder.
That will scrape off the varnish and give you an unbiased answer.
And I see a few threads from the past about hydraulic roller lifters , so give the search a shot. Too much information is never a bad thing....especially when there is a 4-5-6 hundred dollar price tag at the end of the equation.
