Pivoting from 340 to 360

If you are talking the KB 190/191s then you might be able to run 10/1 and if you can run full timing, that would make a great combo with all the parts you listed.
That 220/224 must be pretty similar to the 224/230/110 Hughes I used to run., which was a dynomite little torque monster in my combo. I revved that little guy to 7000 all the time; but I had OOTB Eddies on her with the AG intake and TTIs. The point is I loved that cam,I didn't mind the layover after 6000, cuz with 3.55s that didn't happen until 53 mph with the combo I was running, and 7000 was 62mph. And when I downshifted into first at 32 mph, the Rs jumped to 3600, and she was gone.
That's a really good street combo....... just not at 170psi and iron heads.

But if you don't run a tight Q, you are looking at 170ish psi, and that won't fly on pumpgas. Even with Tight-Q it'll be iffy.And you will forever after be forced to buy Premium gas.So; measure,measure, measure, and calculate.
With no quench,I'm gonna throw in with the guys recommending 9.5 or even 9.0

But really that cam,IMO, is a wee bit small.It may cost you extra machining to get the Dcr down.
Figure it out; the penalty for being forced to run premium gas quickly outstrips any fuel economy gains, in the cost per mile calculation.(* see below)
So you might as well move up a cam size which will close your intake about 3* later. The 360 is a cheap throw together at about 9 to 9.5 with those pistons. When you throw that into the mix you get about 150/155psi and badaboom you are running 87 to 89 fuel. The 3.55s are still ok, but the 2000TC is gonna be a little soft at zero mph. And this next bigger cam will still be happy cruising with 3.55s

But that 600 , for me, would be a doorstop PDQ,No matter which cam goes in. I tell you what, get yourself two straws from the kitchen, stick 'em in between your lips and start running.How far did you get? Mark the spot. Go back for two more straws and repeat,lol. Ok, I'm just funning ya; don't do that, you might have a heart-attack!
The point is I have a 600vs, a 750vs and a 750DP, and an 850TQ.Not to mention the AFBs and AVSs on the rebuild-shelf. My 367 likes the 750 best for all uses except fuel mileage runs. For that I modded that petite 600.

But I like that 220/224, and having run the similar 224/230/110 some years ago, in a 367 cuber at something like 190psi, I can tell you that with 3.55s, it was a blast. I would still be running it 14 years later, if it hadn't begun dropping lobes in 2004 .

In regards to cost per mile
I bought aluminum heads so I could run close to 200 psi on 87E10, with full timing. Guess how much money I saved in 100,000 miles of running those numbers. IDK either cuz the comparison is not fair. I know that with the smaller 224/230/110 cam I was getting mid 20s all the time, with 3.55s and a regular 4-speed; and low 30mpg with the prepped carb, on the hiway with a double overdrive combo.
So lets say 25mpgs for just 60,000 miles is 2400 USg.
With closed-chamber iron heads I woudda run 160psi max and 89 gas I think. And with the loss of pressure, I might have expected 15?mpg. So; 60,000@15 is 4000USg. So Lets say I saved 1600USg. What's that come to in dollars? More than $6000?,plus the difference in fuel costs;Hyup enough for a complete engine rebuild, and more.And that's being conservative.
I loved that cam; shouldda never got greedy with the following 230/237/110cam; it has a completely different personality.
