My First Stocker Cam

Tom,old OEM springs should be good for break in.

Like Billy said that probaly won't be your only cam, and 2 bbl is whole different deal it is easier to be too big,usaully ex. duration does'nt need to be bigger than intake duration,due to ex flowing high% of intake,ex could be 90% of intake flow verses 70% in unrestricted intake combo as example. Check lift @ valve w/spring pressure you'll be running, if comes up short of .407 then you can have amount short added to next cam,leave,I probaly would shoot for .400 to be sure I checked legal.
If don't have valve train yet try to make stiff as possible.

Dwell does'nt have to have Shubeck style lifter,spring pressure is reason for that. There are dwell nose lobes that were ran back when stock spring pressure rules were in effect.
I would say that 130-140 seat and 325-350 open would work with your cam and 6000,but I would verify w/ Tim or Chris. You might have to set seat pressure higher to get open press right,but won't matter,because what does damage is open pressure too high.
You can use race hyd. like they said,but lifter w/.015 travel will be faster,due to it not compressing,no matter what a real hyd. is going to compress some.

You may want use the race hyd. this time,to save $'s, especially if you are trying to get a baseline on your combo,and you can always upgrade lifters later w/out changing cam.
