Sound ok?

Give it a shot, try second to lightest, and lightest; one on each side. The HEI re-curve kit is cheap at the parts store. It works for the standard dist, not sure about the big block one... don't know why it wouldn't... From the specs you gave me awhile back, it's like my cam; it likes a fast curve!! If that works, try all light and see if that makes a difference.

Light springs made a hell of a difference, reminds me of a leash, it's almost like the entire engine is tied to it.


You want the slack just tight enough it doesn't advance at idle, come on quick and hard up to 2500. You can feel where the rest is up to you.
