not to change the subject, but I have a somewhat related question. In the long run, will it be easier/cause less problems to swap the tbi 305 in my car with a carb'd 350 or just toss the 305 tb on the 350?

 

As long as the swap is done properly, either is fine. Its up to you which one you're more comfortable with.

 

Well obviously I would rather keep the fuel injection system than switch to a carb but I was just afraid of computer issues. Will I have to modify the ecu/programming if I'm building a 300 horse 350?

 

The 305 throttle body will fit on the 350 but you will need 350 injectors. I did the same thing on my '95 GMC truck. Don't believe I had a problem hooking up the 02 sensor.

 

Ok, are there any other important components I will have to change/ replace?

 

The knock sensor, probably the PROM.

 

can you give me any info on what I need to do with the knock sensor? sorry to be asking so many questions but I just want to make sure I do this the right way.

 

Get a knock sensor for a 350. You can buy new ones for not much money. Get one for a 350 TBI or an L98. They are probably the same. All you should have to change is the knock sensor and the fuel injectors for 350ci units. Computer tuning will have to happen too, more than likely.

 

Ok that makes sense. I figured since I am embarking on this project I will go ahead and beef it up some. If I am going to do the whole bigger cam etc etc and push somewhere around 350 hp will I need to consider any other components to be changed out?

After this question I hope to be able to finally have enough info to start on this darn swap. So bear with me

 

Anyone feel like tossing in their 2 cents?

 

You would probably get better response by starting a new thread

 

You changed the topic. You're not supposed to do that according to Board guidelines. Therefore, I moved all your discussion into its own thread.

 

Oops! that's what I said...
