Well, my birthday is coming up, so naturally I start thinking about what I could do to make my car faster. I currently have a the L03 TBI 305, yeah, the motor gets laughed at, so I was thinking about switching it up to a 350, and that leads me to my next problem which brings up many questions I hope you gentlemen can answer. I really like the TBI system on my car, it doesn't have all the mechanical cables that a carburator has and it doesn't have all the sensors and weird looking intake manifolds that TPI/FI has, all it is is that one little unit on top of the intake, so I was wondering if there are alot of TBI 350's out there to buy, and would that be a good choice? If so does everything just hook right in like it would with my 305? The PCM? all the sensors and what not? probably not right? What else needs to be bought along with it to keep it a 350 TBI?

Or I could just get a carbed 350 which I'm sure are much more plentiful, so if I get one of those I don't even need the PCM anymore correct? Thanks alot in advance guys, just answer as best you guys can.

 

you can do it just fine. All you really need to change is the ECU, and you can reuse the intake manifold and front accessories on the 305 so you don't have to change the wiring harness. Everything else is the same on both motors.

 

I see "Location: Temple City, CA". That means you need to be a little careful about what you put in.

The only "legal" option is a '90 or later B-body LO5. You would have to be able to show you have all of the emissions equipment that set-up had. Shouldn't be much of a problem, because the main difference between them is 45 cubic inches.

LO3 exhaust chokes a 305. What did you have planned there? Again, it has to be applicable to the "donor" vehicle.

 

how much does that run? a 350 is enough as it is
