Has anyone done a engine swap on a 90-92 camaro Rs with a 305 tbi to a 350 tbi. I live in california and was considering a zz4 gm crate but i dont think it will pass smog? can i use the z28's 350 from that year minus the tpi? Any tech help would be nice. I also will probably be upgrading to edelbrocks efi setup. thanks.
