Opinions on what to buy to lower ET...

I have some money earmarked for the car and I can’t decide what to do with it. Currently the car runs fine and hooks hard and pretty consistent. Current times are in sig. Here is the combo:

410 small block, 10.8:1, pump gas, ported Eddys, small solid roller (248/254 duration @ 0.05 with 0.576/0.582 lift)
Victor intake, 750dp, 727, 8” converter, 4.10 gear, 3200#’s, stock suspension with drag shocks and a snubber.

I was thinking of doing one of these, but I only have money for 1…not both.
1. Buy new 950 carb to replace the current carb (650dp with a 750 Proform main body, so basically a 750dp).
2. Get full Caltrac setup with mono springs.

IDK, I think the car would benefit from both, but there is only money for one at the moment. Any help would be appreciated.
