I honestly think you have to get in some cars and see for yourself what they're like, I know my perception vs what I read in newspapers and what I see online are different. I personally think a lot of guys just pass information on without having real experience.
First one that comes to mind, I drove '66 Fairlane with wide ratio toploader, 3.89 gear, 466ci 385 series, 850dp, Torker manifold with a Comp 292H. I think perception is with wide ratio and 3.89 this would be "ok" but with single plane and decent amount of cam in it and the 850 which has larger venturi which some call lazy, most would consider a little iffy for street? Well, first time driving a toploader, I started out in third gear by accident...twice...and didn't stall it. Did same thing pulling 4th instead of 2nd and it handled it at low rpm. Pulled absolutely fine at 2000, started to pull hard around 3500. Definitely knew it had some cam to it but would idle steady at 900rpm all day as I recall. Considering ports in a FE are smaller than a 460 based motor, I'd think torque would be stronger down low and in the midrange. Guessing 3800lbs with driver.
250ish degree solid roller in a 427ci SBF, AFR 225 heads, Super Victor intake, toploader and 3.50 gear in a '63 Fairlane. Two dudes in the car, guessing 3700-3800lbs? Had to be lazy down low with the large cam, big intake, mild gear? Car was an animal on street tires, stupid. Guy eventually got it to the track think it did mid 11s but at 125mph or so. Again, had some cam to it and wouldn't run power brakes, but it didn't load up or act snotty around streets of Detroit. Part throttle running around shifting 2500-2700 it acted fine, that said it was not a sub 2000rpm combo.
My little 390 in chubby '63 Merc. 224/230 hydraulic roller, TKO 500, 4.10 rear, 750dp, Performer RPM. Handles Overdrive fine at 1600rpm if needed, it will accelerate just fine in O/D anything over 2000rpm. Car idles all day at 850rpm, I can idle it down to 650rpm if I really feel like it but I like it to sling around a little oil at idle, plus it is pretty sloppy when cold if I try that. I'd literally run this in a truck application (maybe just swap on a vacuum sec carb), no issue, on a chassis dyno torque peaked at 3500rpm.
A 445 will handle 230* cam no sweat unless you're putting it in a tow truck, put good modern cam lobes on it to keep advertised duration in check, put a good sharp timing curve in it and get the carb working nice and crisp at part throttle and it'll be an incredible combo. I think the biggest feedback I'd give is get for making a car streetable is get a modern Overdrive in the car, someway somehow. TKO trans has a deep first gear to help with any softness down low, O/D lets you run plenty of gear but still cruise easy on the highway, I run 2200-2300 at 70 with a 4.10 gear and it's perfect. If for some reason you run an auto, modern autos can run lockup convertors in O/D and keep heat and slushiness out at cruise, and I believe most modern o/d autos trend to deeper first gear.
Video I threw together of putzing around going to work, some lazy shifts at 2200rpm, some WOT stuff, just as a reference. Cam guys can confirm, but I'd think the 224* cam in my 390 would act about the same as a 230-232* cam in a 445. I have weak suck 9.2:1 compression, most 445 combos are going to be higher than that so would be a bit crisper down low.
