Nothing wrong with the carb.It would like a dual plane a lot more though.Heck,even a used performer or CH4B would be fine for less coin than an rpm.
With the torker intake it would like a vacuum secondary carb best for your application IMO.It would'nt mind the low stall as much with the vacuum carb either.

But hey you have it so put it together,tune it,and get a baseline.Then see how much you can pickup by trying an intake or what ever else comes along.

I built my 496 with used/leftover parts except for the pistons and I chose the wrong ones for the compression I now want.It still runs pretty well.
