LS Swap Cheaper Then SBC Build?

[SierraMtns]

I am looking in to doing a LS swap in my 67. Currently I have a built 283 with MSD dist, weiand intake, rebuilt q-jet carb, ect. At first my plan was to keep most of the accessories and get a 350/ 700r4 trans but after looking around it looks like I could do a LS swap cheaper. But maybe not. Things I would have to figure out, dash gauges, computer, motor harness.

Is it possible?

I have a Boyd tank already but would still need a intake fuel pump.

Thanks
