Ernie,

The settings for my roller rockers on the big block are .027/.028.
That .040 sounds like a lot of gap and if the car wasn't so noisy already you would surely have heard it. Even before Ilowered my cams profile the setting was still the same. And I had a 312 duration, .630 lift cam with 96 degree overlap. The new cam is much milder than that but sure pulls a lot better at lower RPM and is a lot nicer to drive with. I think it just has a .535 lift and 292 duration with about 84 degrees overlap.
