If your using conventional oil, as in pretty much any of the shelf 15-40 etc, use a freaking additive....I havent got a clue why your being told different, because the info is wrong, period. And its $6 bucks added to the cost of your oil change maybe twice a year.....so if this is actually a conversation over $12 a year in protection to help your motor live a long life and you listen to anyone who says its a bad idea then good luck.

You may be misreading my post. I didn't say he shouldn't use additive, or zinc. I said too much is not good, and don't use break in oil after the engine is broken in.
All the newer SM and SN rated oils need additive, but not break in oil. I use Brad Penn because it's cheaper and better per oil change at around $6.25 a qt. than to buy regular oil and then buy ZDDP at $12-$13 a bottle per oil change.

This was my recommendation:
"I think you'll be fine without any additive to oil, but that depends on your oil of course! Too much zinc is bad also, so don't go overboard on breakin oil or additives! I use Brad Penn oil in my flat tappet engines, and I put lots of miles on them. It's the old Kendall factory, and is made to specs for early flat tappet type engines. "

Ahhhh, yep, I miss read, I had an argument recently about someone not wanting to spend a few bucks per oil change on an additive, or use the right oil, brad Penn, Joe Gibbs or what not, so I may have shot my mouth off prematurely lol.....
My apologies

I'll have to look up that Brad Penn oil, haven't seen it around here.

I noticed on my drive in this morning, that when you punch it (opening secondaries) that is bogs. Doesn't bog,then take off, just bogs. No black smoke from exhaust during this either. I am thinking lean condition?

Carb has all stock springs and needles, so may look into getting a kit for it and attempt to richen up the secondaries. Or may just throw the Holley 650 DP back on and see what happens. I dont know....


Another thing that I have learned the past 2 days of driving it-3.08 gears suck!

Yah, 3.08's and a big tire are no fun lol, I honestly have zero experience with edelbrock at all (and I even use one) but love the 650dp, most will tell you its the wrong Carb for your application but I prefer them.

Congrats on your successful build!

"Too much zinc is bad also..." True that. You might find using ZDDPlus added to a quality over the counter motor oil to cost less but that's easy enough to check out.

The bog could be simply a worn out accelerator pump. Remove the air cleaner and look down the carb venturis. Work the throttle open and see if it you see a squirt of gas entering the carb?
On the Brad Penn oil; do a Google search for dealers in your area. That's how I found my local dealer and he sold me the case for $72.

There is fuel from venturis with throttle. Haven't checked the secondaries ones yet though, but primary, yes.

I have acc. pump in middle hole (normal position) still, does the accelerator pump have anything to do with the secondaries?
I thought it was mainly for the primaries.

I'm not big on Edelbrock carbs, but pretty sure they don't have secondary accelerator pumps. Closer to the pivot point gives larger shot; farther smaller shot of gas.
