timing chain

When Hughes first started selling "fast-rate, made-for-.904 lifters" cams, They flat-out said that their FTH cams had near roller rate ramps on them. When I bought their HE2430Al it spec'd out at 223/230/110 and lifts of .538/.549 with 1.6 arms. I was so excited to believe I had the fastest cam in it's size available with near roller-rate ramps. That cam was a fantastic piece all right, it really was. But it died, and I replaced it with the next bigger Hughes cam, an HE 3037AL.
Some time later, Hughes stopped making those and published the Advertised specs.
It turns out that the 223/230 cam was a 270/276/110 , and the ramps are therefore about (270-223)/2 =23.5* from advertised to .050, which is just not that fast, at all. Furthermore it seems Hughes cams are not spec'd from the same .006 starting point that others usually are. I thought that was altogether somewhat deceptive.
At the time tho, they did have the highest lift for the size of cam, by a fair margin. So perhaps the "fast-rate" is from .050 to max-lift, IDK. I was never sorry to have installed that cam, and was sorry when it dropped some lobes. And I've never been sorry with the current HE3037AL.
But time marches on, and it seems other cam companies have caught the .904 lifter fever.
Sorry to hear you had a bad experience with them.
