I have a 91 305 TBI 5 speed, I have a buddy with a 305 TPI out of a 88 Firebird, ECU and all wires. I am thinking of buying the TPI off him. I have done some reading on this site and decided to go with the SDPC Vortec intake and Vortec heads. What cam do you recomend for max power on a 305? Also, why do the Auto TPI setups put out less HP than the manual ones? Is it just the cam or something? Thanks!!

Also, what problems may I encounter trying to use the wiring harness from a 1988 Firebird on my 1991 RS, should everything still hook up, will the speedo be jacked, or will that also hook up? And the Air Bag, does it work off the 1991 computer, or will it still work? This will be a HUGE job, I am aware of the fuel pump/lines needing to be changed, does anyone know of any other problems I will encounter, all help is greatly appreciated, Thanks!!!
