Nothing wrong with old technology. Carbs are easier and cheaper than fuel injection.
I fiddle with my carbed 2F way more than my EFI 3FE... plus the idle. EFI is sooooo nice once it's done right.
I agree with cheap and easy.
2F; heck, even a 3FE...
chevy ls swap is growing on me in my old age. having done Camaros and big old fords, I've decided that MORE is not always better. the ls will be a lot easier on the gas tank than a carbed 350, but cost more outright.
bear in mind, in Cali, you must use a motor that is the same year or newer; AND the same size or bigger, unmodified, with all of its stock trappings in order to pass C.A.R.B.
