Thanks for your input.Silversled wrote:If you are going to be beating on your car and bouncing it off redline, I would also recommend uprating the springs to some PAC or other beehive style. They are cheap and the extra spring rate will help the heavier valves in our heads from floating. Don't bother with dual springs unless you are going to a much higher lift with an aftermarket cam.

I'm planning on setting the L77 up like a LS3, 6200 rpms. However, I did not consider the valves.
My plan is LS3 Cam, blue valve springs, DOD delete with new lifters, maybe injectors but haven't calculated that yet. I'll block off oil ports like you suggest.
Then I was going to tune the fuel/timing/trans using a SS for baseline.
I'm not planning on flogging the caprice. I've got a blown ls1 fbody for that.
Is there any reason to think a 6200 rpm fuel cutoff is too high for the L77 valves?
Any advice on switching out rockers or other parts (135k miles)?
