could i put a tpi setup from a 305 on a 350 ? i can buy a 305 tpi but i would like to know if i should drop it in or put the tpi setup on a 350?

 

the tpi is the same...

its actually designed around the 305..but gm threw it on the 350 as an afterthought..

 

so theres no difference physicaly. what about in the ecm?would i have to have a chip ?

 

You need a chip, a 350 knock sensor (tuned to the different knock frequency of the different bore diameter), and injectors that will supply the correct amount of fuel for a 350.

The TPI itself is the same.

 

350's came stock with 22# injectors as opposed to 19#.

 

Are you sure about that? Just asking because I have always heard that the TPI was originaly designed for, and used on the 350's, in the vettes. As far as I know the vettes had the TPI a year or two before the camaro.

 

Completed that swap two years ago using my old 305 TPI on a 350 with just the items mentioned previous.

 

Just get a different chip and injectors. Then add a new knock sensor and you are in business.

Although to take advantage of the 350 I would recommend porting your plenum and base. Siameasing the runners, and maybe adding better fuel rails.

Or better yet go with a Super-Ram or a Mini-Ram. I know several people on here swear by the Stealthram but I would not choose one because I have heard that they are a pain in the *** to install.

I find that the Super-ram is the choice for maintaining a smog legal car. The Mini-ram however is decently priced and easy to install.
