Sizing carburetor

Some of you guys need to learn to read that cam card,
on the left is advertised
on the right is at .020 tappet.

020 tappet at 1.5 ratio, is .030 valve.
and .300 x 1.5=.450 valve
and .030 plus .450 = .480
case closed.

I like that cam.
With plenty of cylinder pressure, the right timing curve, long-tube headers, and a free-flowing exhaust, my guess is that it could make excellent street torque, and I'm sure I could gear it to run 65= 1600, and with a manual trans, make point-to-point fuel-mileage in the high 20s, with a small TQ.
I mean check it out, it has 118 degrees of power extraction! In a long stroke 360, that alone has a lotta potential.
However, in per the camcard, the Ica is 65*, so, to make pressure with that is gonna take a fair bit of Scr.
The numbers look screwy, but once it's mapped out, the only things that take a hit are the effective overlap, and cylinder pressure. You can't do much about the overlap, but you can deal with the Ica.
For on a budget, I'd run it. It's like a factory 360 2bbl cam except with 340 intake duration. I'd even run it with the 188 valves.

as to carb size, on the street, anything over 500 will work, cuz with 3.23s you're only going thru the PowerPeak the one time, and probably spinning the tires anyway. Getting into Second she'll top out at about 65@4200@10% slip; so you can just run whatever you already have, that is known to work.
Now, if you have to buy a carb, and intake, that's another story..
In that case I'd like to run a metering-rod Spreadbore, like a TQ. But I would not run any spreadbore carb on an adapter to a sq-bore intake.
That cam is gonna peak at around 4900/5000rpm so the AirGap intake is more than you need.
If you already own it, then fine, just stick any old carb on it.
But, if you don't have an intake, just grab anything, even a small-port, small plenum, single-plain, but then I wouldn't bother porting those X-heads ................... which I wouldn't bother with anyway for this particular cam.

But you know, what do I know......
According to some; you should run a 273.
Anybody that knows anything around here, knows that 273s are the bees knees.
Oh, sorry, I meant 318s are the bees knees.
Oh, sorry, you should run a 7500 rpm 283 Nova with a powerglide,
Oh, sorry, you should stroke it.
Whaaatever.
This place is like the ocean;
everyday the tides go out and the tides come in,
and one day it's calm, and another the waves are raging.
Going fishing is a crapshoot; you can have the best equipment, and you can stay out all day, and you can still go home hungry.
