Be advised this is not a plug and play swap. If the 350 TPI is 90 or newer, your firewall harness will not mount up without modification or switching to a 90+ dash (on Camaros, don't know about Firebirds). Plus, you will need to use an intank fuel pump and the needed hoses. Also the engine harness and computer harness could be one (90+, 89- is still seperate). I should know, I am going 305 E4ME A4 to 357 SD TPI WC T5. Plus I am contemplating switching my dash to a '90-'92, that way I can use the electrical speedo, which is needed for the SD 7730 computer to operate the FI.
