go LS, carbed if you want. at some point you may want the convenience of fuel injection so then you are all set up except for wiringand a few other items. you will need an oil pan kit with baffle, dipstick and tube, pan, oil pump pick up. they are all over ebay. I used a camaro pan. the stock camaro exhaust manifolds will also fit between the frame rails if you are trying to keep the cost down, whereas the truck ones are too wide. the truck engines are cheaper to buy so price it all out and see what works better, a camaro engine, complete, or a truck engine and then buy the add ons. cheaper to buy a wreck and take what you need, then sell the rest. that way you get all the stuff that works together. noit as big a deal for you if you don't plan on injection. if going with a crate engine make sure to ask what it will come with. p/s pumps, alt. belt set up etc.
I know you want to go with a carbed engine and a ditributor but the injected LS engines can be made to look cool too. they start easy, run smooth, emit less odor and get better mileage. up to you though. if a daily driver I would go LS personally. thats just me.
