For a brand new engine? Seems should be higher.
@Johnny Mac . you here.?

Agreed. Just seems low. Especially in gear and running at 55 mph.

For what it’s worth, my poly is hovering at 45 psi at idle, 60 psi at WOT, but not with a load or in gear, haven’t got that far yet
Those shrouds I have are '70 up probably /6. Should be fairly easy to find in the state of paradise by the sea.
The question is how that might fit or be fitted on an early A and whatever radiator is being used.
Here's intact one laying on a '68
Why are you changing water pumps?
The Edlebrock pumps are like that. They supplied fittings, but they were brass fitting for the aluminumn pump.\

Bigger problem was the pump needs to be ground back a bit to fit. Told 'em - sent 'em picks. Bet they never fixed the issue.

Ran hot.
Found out I had 6cyl rad.
Wrong fan and spacer. Bought the correct rad, fan, spacer. Then water pump and pulleys were wrong.
Bought those. Cast iron water pump fits ok. Just need shorter bolts and nipples. Just ordered bolts. Still need nipples. Que karl.
At 55 mph 55 psi
Good Evening All! Whew what a back read, working working yesterday with honey do's after work : ( Going to be an interesting week, moving son to Spokane on Friday so 6 hr trip in 89 Suburban loaded, over the mountains, 99 degrees day of arrival 101 day of departure. Staying overnight. Wife flys to Michigan for brothers remembrance on Thursday, comes back Monday.
Thanks for all the pics of your ride, enjoying following your progress!
High volume low pressure is best I think. 50 pounds at 55 is g ood to me.

Speaking of oil pumps. What’s the best way to paint one? For the 440. Tape it up?
There is some minor difference between '67 and '68-9 radiators and shrouds.
Maybe the shroud mounting holes? But really have no idea. . Maybe ask in cooling what the difference is.
Here's the '68-9 shroud (repro)
The fan opening is about 20"
Center of the fan opening is about 10" from the passenger side shroud mounting holes
Vertically the rightside mounting holes are about 2 1/4" and 15 3/8" about the bottom line.
First time on today. Returning pm
Why do you want to paint it?
My recollection is oil pressure warning light comes on at 8 psi. 10 to 15psi is fine at a slow idle and fully heat soaked engine - which 210 on the water temps suggests it is. Tims engine is idling relatively high so more pressure seems ballpark correct to me.

It’s external and figured since everything else was painted, May as well
Not warm at idle.
Under a load yes. But the 50 at 55 for a higher rpm engine seems fine to me.
Fan on the car is a 6 blade 17 inch. 20 inch opening seems excessive
The 408 in my 69 vert ran 70 all the time...
Agree. First time on today, and said about the same in my PM. 20 at HOT idle is fine with me. 55 at 55 mph is fine with me also.
If it idled at 70 psi....i would suspect a high pressure spring.
