Weiand #8007 intake on a 273 (Several questions)

There is a lot of good info here, but it won't be fun sifting through it.
The thing that may have gotten lost is that with 4.10s; 30mph,my favorite blast-off point, on account of it doesn't all go up in tire-smoke, yeah so, 30 mph is about 4100/4200 (in kicked-down to first),with 25.5 tires. By this rpm the engine doesn't much care about it's low compression, nor it's stall speed, nor a bunch of other stuff.By this point all it cares about is getting air in,the hardest job of all.
So a super-fast-rate solid lifter cam and a big carb,headers,and the biggest,fattest,most free-flowing exhaust will all help to make that happen.The key here is the 4.10s. And while I don't always agree with YR, I think he pegged "A" pretty good combo, without digging into the engine. It wouldn't be my combo, but for the price of admission, OP could do a whole bunch worse.
I mean what are we talking about here? Gears, headers, and a 4bbl,(any 4bbl,any intake, to get started). A little icing would be a TC to get some snap off the line. I see that as in the neighborhood of a G, plus labor where outsourced. Where on God's green flat-earth are you gonna buy this much fun for a grand?
OOps I forgot the pipes and mufflers, let's call it $1500
