Solid Lifter Springs I will be looking for a good solid lifter spring for about .650"-.700" lift and 7400rpm. What do you guys recommend. I would like something that would last with some street miles as well. Comp 999s, etc. I understand that there is a drop in solid lifter spring, will it be able to control that kind of lift at about 7400 rpm?

Someone has got to know. A better question may be what kind of seat and open pressure do I need for something like this? Maybe 250ish/650ish?

I am using a .730/.714 260/271 solid cam and we just set the springs up at 230 seat pressure and about 660 open pressure. I used a Lunati 1.550 spring...cant remember the PN offhand. But there are quite a few out there. Cutting 1.550 spring pockets is a little tricky...but that size opens up alot of alternatives for springs.

I am running .100 longer valves. On my current spring setup with .730 lift on the intake and the way the springs have been installed I will have approx .110 left before coil bind at .730. It will actually be a lil more than that after setting .018 lash.

What springs are you running and do you drive this combo on the street at all? Also, are the valves 8 mm or 5/16" with new guides?
