Hello and welcome to the board. Even though someone swapped in an Olds 350 all the brackets, etc will interchange with the 403. Are you planning to put a 403 back in your 79 TA?

I don't know all I should about the regs in California to answer that question. But, I would think that you could get either the 350 or 403 past emissions with a good tune, cats and muffler. After all, CA cars came with 403 Olds engines.

I'm sure Russ can jump in here and tell ya more about what you'll need to do to pass the sniff test.
