There is a guy on here that is hooking me up with a new set of springs and retainers off a set of stealth heads, I am going to be using a firecore vacuum dizzy and their pro-fit wires, msd blaster 2 coil, with the HEI upgrade for the ignition system. Getting a good deal on a case of brad penn 10w-30 right at $60 for a 12pk, the break in oil I am sure is gonna be cheaper still, and also have a case of wix filters standing by, I am going to be running an external pickup and I am concerned about the size difference in the HV vs external milodon pump covers, should I worry about enlarging the holes at all ?



so your saying to use an additive for the break in, and first 2 oil changes ? I thought that the BP had high enough ZDDP to not need anything else ?

I should use 20W-50 in a freshly rebuilt motor ? I figured 10W-30 would be plenty thick.

I run an aeromotive 340 stealth intank pump, so the bowls should fill quickly lol

I appreciate clearing up on the header vs manifold issue as well,

Thanks as always guys,
-Mike
