350 is quick/easy/cheap. LS takes time/money/effort but yields outstanding power.

how much money do you have? how comfortable are you with wiring? LS swaps are hard to beat, but they do come at a cost

"Los Angeles, CA". The only legal carb is the type your car came with.
$600 isn't much for an engine, unless you're willing to live with what you find used.
There is a tech article linked from the thirdgen.org homepage about swapping from auto to manual trans.

Re: 305 to 350 or LS?
A 350 will drop into the same spot as a 305 as they are the same block and use the same accessories and everything else. But a 350 will need more fuel, adjustments to carb & timing, and some other stuff to work 100%. A carbed 350 with some minor performance parts is going to be in the 275 to 300hp range.
An LS1/2/3 is going to be about 150lbs lighter, give you over 300hp in stock form (with proper tuning & a free flowing exhaust) and is a major upgrade - not talking cutting and welding, but a lot of things have to be changed.

Re: 305 to 350 or LS?
good catch. being a Cali car, any engine swap is going to be more costly than most of us have to endure. if you decide to go LS1/2/3, you're going to need to get *all* of the emissions parts off the donor car

There's no such thing as an "emission-free state". There are states that don't do inspection/testing, but the emissions laws apply to all 50 of the United States.
Except California is allowed to have more stringent requirements than what the Feds impose.

Re: 305 to 350 or LS?
Keep the 305. As I said in another thread, it was recently rebuilt and as was the 700r4. Swaps don't come cheap and unless that 305 was shot, I wouldn't recommend a transplant. You have a nice car in great shape considering its age. Keep it that way. Wish I could have kept it.
