Kaama,

You shoulda' called Bruce (Crower) or one of his boys up and explained to him their mistake and your situation. I'm sure a pair of their cranks or billet rods woulda' smoothed things out, LOL.

so budah i should go with 140 lbs spring now how will that help it live longer?

Better able to preven valve float and will keep the lifter on the lobe as the rpms increase.

I agree.

the reason i asked i did not want to kill the lifter. also why does crane only recommend 130 lbs if that is not enough

I ended up changing the cylinder heads I'm going to go with, instead of the "as-cast" AFR 305's, I'm going to get the CNC ported AFR 315's. The intake flow is increased 20+ cfm across the valve lift range, with similar improvements on exhuast flow. More efficiency = more power.

So now I'm looking at:
RPM.........HP.......TQ
2000.......249......653
2500.......322......676
3000.......386......676
3500.......448......672
4000.......503......661
4500.......552......644
5000.......578......607
5500.......580......553

AVG.........452......642

This old Thread makes me think how far along technological advances in the engine industry has come with several and various components like, MLS Gaskets, Lifters, Cnc ported Heads, etc, etc,...and various Cnc Machining Technology.
We've come a long way since 2003 🏁🏴‍☠️🏁🏴‍☠️🏁
