My guess the OP is looking for a cam to go with what he's got not to redesign his driveline.
But I could be wrong, I get what your saying but don't get this Doomsday Apocalypse of low cr and mild cams, tons of people have done it and enjoyed the results is it ideal no but sometimes you got to work with what you got, there's been at least 3 guy's here put a 280 ish cam in a low cr 2bbl 273 long block one with 2x4 tunnel ram and been happy with the results.
318willrun puts cams in low cr 318 all the time and gains with track results but you say it won't work yes cr stall gears are important but unfortunately are the least likely things people will and or can afford to improve, intake cam exhaust is what most are gonna go for and shown to work.
