Does anyone know if the tps/iac/throttle linkage on the 454 TB is the same as on my 91 305 TB? I know there are some differences in 454TB's depending on the year but If I want to convert to the 454, can I still use the tps etc from my existing 305 TB ? What year 454 TB will work?
I tired the archives but couldn't find a clear answer./ Thanks for the help........bob

no they are not the same. yes the tbi will work, but it will require rewiring.

 

does anyone know if my 91 style small block TPS and Iac will bolt/screw in to the 454 TB? I was just going to order the base and use my injector pod........bob

 

you will have to get the 454 tps. ill take pics of em both and post em for you if you want. they are completely different.

 

you have to type this into your address bar, and then it only might work.

SNFLU, you are da man. I am gonna look at the pictures right now. Thanks for making that possible...........bob

 

snflu,I checked the pictures. Man, that really helped. Do you know what year the Big block TB is in your picture? The reason I ask is I read a post where the later Big blocks (after 91) had the same tps and Iac as the small blocks.Thanks for all of your help on this...........bob

 

i guess that may be. but i guess you would have to ask these guys.
