I have an older (but brand new) Comp Extreme cam pn #48-000-5 - grind# 409 6054/6055. This is a solid lifter cam.
I have the Comp solid lifters also new. The motor is a Chevy 1964 409 ci. 11:1 with 690 heads, Crane 1.70 gold rollers and 4-speed.

I would like to know what valve springs I could use (part number) and if beehive or a dual spring setup is the best. RPM range to 6300
This is taken off the cam card:
Lobe separation is 110.0, lift is .554 int and .569 exh.
Valve adj at .012 intake and .012 exhaust
There is no valve spring recommendation nor can I find any information on this cam. I have called Comp cams and they can't find any info either. They said it was discontinued and not carried in the catalog.
I may take it to the strip, but more street and car shows.Thanks for your help.
