My 283 turbo sbc hasn't been cheap since I want it to not blow up on the first time I test the power. I've built it to be a blow thur quickfuel carb setup.which is one of the easiest carbs to work on if needed. Going carb is cheaper than going efi but you have to have knowledge of carbs and how to tune it properly. A wide band o2 sensor is your best friend when it come's to tuning.
