Thanks for explaining that, Pat. I've just looked at Lunati pressure-fed solid rollers and they cost quite a few more $$ - oh well, c'est la vie!

Another question (sorry!) - what's your feeling about dual-pattern as opposed to single-pattern cams? I've read that dual pattern work better to compensate for a weaker-flowing exhaust side. I've got Edelbrock Performer RPM heads and pretty free-flowing equal-length 4 into one headers and 3" main pipes with pretty unrestrictive mufflers. Would my engine benefit from a single-pattern cam, do you think?
Lunati have a solid-lifter cam 304/304 (244/244 @ .050") 110 lobe centres and .595/.595" lift, which looks interesting. Part #50200LUN.
