Hi, I have a 1968 i would love to get on the road again. It has been sitting in a garage for 24 years. The body is almost perfect, with next to no rust. The engine is done, and I am wondering which engine i should put in it. Should it be a standard 350 (the motor that was previously in it) or an LS1 or LS3 engine? I would love to hear what you have to say about it. And also, please tell me about other things i have to switch out of the car since it's been sitting for 24 years.
The stock 350 would be the easiest, but ultimately the choice is yours. If it were mine I would drop the tank and clean it out and blow out the fuel lines. You will probably have to rebuild the brake calipers as well. Any and all rubber hoses, including vacuum , will most likely have to be replaced as well. Obviously the tires will be dry rotted and make sure all the grounds have been cleaned and are tight.
Easy and cheapest way to driving this car is to keep the original 350. As for getting the car back on the road replace all rubber items that have liquid traveling through them, brake service and inspect the gas tank for inside rust.

Yes and get the carb rebuilt, probably expect to have to replace some seals in anything holding oil or fluids, if they dry rotted as well. But I would wait for whatever is going to leak , to leak. Obvioulsy a good tuneup/ oil change to that 350 and oil and filter change to an automatic. The rear bushing and seal in the tail shaft of either auto or 4 spd tranny may be shot as well
C3- I would also vote for putting in a NOM 350, since you can get a dependable crate motor with performance characteristics from mild to wild at a reasonable price and it will match up with your existing bell housing and other connecting points. Other issues- check the gas tank for 24 years of built-up crap. If you are lucky, there will not be any rust thru of the tank and you can just clean it out. Replace all of the rubber gas lines and flush out the long metal lines to get the dirt out. Most of the rubber suspension parts will be dry rotted. Some are easy to replace, the A-arm bushings are more work. You also have decades old electrical wiring. If you are lucky, no previous owner has cut and spliced so that you can not tell which wire is which. Brake calipers and hoses probably need replacing, the rotors may still be OK. The 50 year old rotors on my 68 convert were like new (excellent steel used back then). Your radiator may be OK, but a replacement aluminum one is not that expensive. Suspension parts like tie rod ends, ball joints, steering gear may be OK, but are easy to replace. Hopefully your transmission and rear end are OK, since they are $$$ if you need to fix or replace. Exhaust system should be easy to check for rust out and leaks. Sounds like you are now in the car restoration business. Good luck.

really good reply that gave me a lot of help. Really appreciated it. I will try my best to get it back on the road
Regarding the LS engines, awesome power, easy to make stronger. downside? Its a lot of work and exta expense to swap in. Kits are readily available for Radiators, headers, engine mounts, trans you name it. But none of it is free. Plus, a well installed and detailed sbc in a C3 looks like it belongs. I have an LS3 in my 14 Camaro, its over 100 hp less than my new sbc in my Corvette. So..... I guess Im saying, easy install, very capable power, looks right, what more can you want?

Thank you in advance
Depends on how much time and money you want to spend. Whatever your budget is, double it if you decide to go the LS route.
