A while ago I posted this. (http://www.chevelles.com/cgi-bin/forum/ultimatebb.cgi?ubb=get_topic;f=4;t=018943)

It was regarding me not being able to find dual valve springs for the Lunati 280/280F10 camshaft with a 1.700 or lower installed height.

Well, I think I found something and I want your opinions 1st.

The springs are crower 68405. They have 129 @ 1.65", 338 @ 1.10", 382 lbs/in, and a coil bind of 0.98". At full lift with this cam it will have 326 lbs of pressure and will have 129 lbs on the seat, and has over 0.15" left until coil bind.

How's that sound?

Like almost perfect! They're duals so you can run it in on outers only? Then they'd be perfect! How do they compare with the Isky's Harold recommended?

Crower Springs Isky Springs
Dual Single
129 @ 1.65" 130 @ 1.70"
338 @ 1.10" 339 @ 1.15"
382 lbs/in 380 lbs/in

What's really prefect is that the crowers have a 1.40" O.D. and fit in a seat cup with 1.440" I.D. Those cups have a 1.55" O.D. and my spring pockets have a 1.55" I.D. :D
