Hi.

I have a new set of crane valve springs I would like to use on my engine but I am worried that they might not work with my camshaft. I need your opinion

Valve Spring Specs

1.440 1.040
No dampener
95#@1.703
260#@1.200
1.080
328 #/in

Camshaft specs

221 degrees at 0.050
.496 lift

Thanks again!

Terry

Simply shim them .050" tighter for a 1.653 installed height. That will give you approx 111 lbs on the seat and 276 lbs at full lift which will be at about 1.150" That still will leave you .070" from coil bind height. Just be sure to measure everything. From the specs it looks like you've got the room to do that. A seat pressure of 111 lbs should be good for at least 6200 RPM.
