I got the Crane Powermax 2050, the biggest computer-friendly version listed in Summit (they do call it "Powermax", but not "2050" in the catalog). It's pretty wicked in my carb'd 305, but your bigger 350 will tame it down a little bit. The computer doesn't mind it at all.
It would probably exceed the RPM capability of your TPI without some mods such as shorter runners. I've only wound it to 5600 RPMs (the tranny shifted from 1st to second since it's unmodded so far, and I haven't had the guts to take it higher in 2nd since I was already well over the speed limit), and it was still pulling hard at the shift. But, it idles smoothly for me at stock RPMs, has more torque across the entire RPM range, and really starts to pull when the RPMs start building up (which is pretty soon).
A higher stall torque converter would be a plus to help the cam start working sooner.
If it sounds too wild for you, try a step or two down (one or two up in the Summit listing). My gas mileage has taken a bit of a tumble (18 to 14 commuting, but I've been "testing" performance a little more than mpg on those tankfuls). I've even considered putting together that TPI in the garage attic to improve that situation.

a local guy has helped me by giving me a parts list of stuff with the camshaft
lingenfelter 74216 with this specs
213/219 @.050 114-LSA
.462/.470 lift
supposed to be a tpi cam and make big power in smallblocks. his car is with carb not tpi, but still runs low tens in the quarter with that cam so it must make something. it is supposed to be hydraulic roller too but the specs don't look all that big.
