my slant buildup

saw alot of talk about that digging up posts on past builds all over online.... I even questioned it myself "somewhere"/ not sure if it was on here somewhere or not... I had bits and pieces of my build ideas scattered around, til I started this thread and a similar one over at the ".org" site. Trying to keep my thoughts, ideas and actual build facts "together" so I can look back later if need be...
and I saw many places where stock 318 springs were used on aftermarket cams.... I know I had asked this on ".Org" and at one point I was told that replacement springs were pretty much "superseded" to 318 springs on /6s, a little stronger than stock original /6 ones...
I didn't want to go crazy on springs, this is no hi rev race motor, it's a truck motor..... I can always swap them out later. I had these, so I'm gonna try them.
Flat tappet engine here, and considering that today's oils don't have the additives they used to, not looking to run something crazy like Brad Penn beyond the break-in/ I drive ALOT, and don't want problems with eating my cam.... If I was gonna be racing this thing, I might have thought different.... if these wind up as "break in" springs, and I wind up having to swap them out, I can do so w/o pulling the head.

On those springs.... they will exert more pressure open, than listed/ spec is at standard, stock cam lift for a 318 (0.373/0.400") at .436 (listed at 0.448" but when you account for the lash setting I come up with 0.436)
Let's see how they work out.
Just give Ken at Oregon a call and ask him what he recommends for spring pressures for your cam grind. The stock 318 springs may be on the light side concerning open and closed pressures but you mentioned that you are not building a 6500 rpm slant anyway.
Hopefully the cam you bought has the HP and TQ peaks low enough in the rpm range to match your intended use.
