440 cam help

I think your compression is too low for a decent hydraulic; I'd steer you towards a fast-ramp solid flat tappet cam

Static compression ratio of 8.8:1.
Ica of 56* at 500ft elevation.
Effective stroke is 3.10 inches.
Your dynamic compression ratio is 7.45:1 .
Your dynamic cranking pressure is.................................... 146.31 PSI.
V/P (Volume to Pressure Index) is ...........................160
This cam with a 56* Ica would be a pretty small cam as a HFT, something like a 256/262/110 and the .050 might be 210/216 but that's what it would take to keep your pressure up to create the fun 160VP

Now; with a solid, and the same after-lash specs; you might get a 217/222 @.050/110, which would be the next bigger cam, but still on the small side.
And nobody says you need a 110LDA cam in a street Duster with a 440.
So It might be possible to get a 262/268 net after lashing/106LDA cam , and get perhaps a 223/229/106 @.050, now yur getting some power out of her.

All of these were calculated with a 56* Ica, so the pressure and VP will remain the same for all of them.
I guessed you are at 500ft elevation. Higher elevations will reduce both the cranking pressure and the VP. 160 is a tire-shredder. With 160 you won't need much of a TC and can run 3.23s or 3.55s with ease. But at only 146psi, she won't be particularly easy on gas. On the other hand, she should run on the lowest octane gas you can find.
You can run a bigger than 210/216/110 hydraulic cam but the pressure will plummet, And soon you will have to install a bigger TC as the low-rpm power disappears. IMO this is a step backwards as nearly 99% of all the hours your 440 will ever drive, are gonna be at something like 4000 rpm or less, which is about 40mph in first gear. With 160VP, you can easily pull second gear with tires still spinning. Well with BFGs you could.lol. That 210 cam might power peak at about 4600 (45mph) in your 440, but with the right springs can continue to rev to 5600 (54mph) about where you would shift into second.
Each of those other cams will pick up the power peak about 200 or perhaps 300 rpm.
On the 1-2 shift, the rpm will drop to 59% (with a TF trans), so if you outshift first gear at 4600, the Rs will drop to 2700 in second, so that 440 better have some power down there. That's why I said 5600, to drop in at 3300, to give her a fighting chance to recover.
All very confusing I know.
Best advice is to contact the cam company of your choice, and get their opinion.
At higher elevations, this will become critical.
