If you want a custom burned chip, talk to JS Performance...they'll hook you up.

Correct me if I'm wrong, I thought the 350 has larger injectors then the 305 ( 305=19 and 350 21 or 22?) or there was some other module as well that needed to be changes as well?

Depending on the year, there are more parts involved.

For TPI cars with MAF setups, you need a 350 knock sensor, 22# injectors, and a 350 calibration.

For Speed Density cars (90-92) you need the knock sensor and injectors, and a whole 350 MEMCAL not just the chip.
