Hey I need a replacement throttle body for my 88 'Bird and Nobody in the state of Minnesota has a 5.0 throttle body in a junkyard and a new one is 300 dollars so F that lol
But anyway i found about 200 350 throttle bodies so I was wondering if i could use the 350 throttle body on my stock 305 with the stock 305 injectors.

I don't know if the vacuum lines are the same or if the fuel feed/return deals are similar or if my air cleaner will sit on top of the 350 TB unit...
anybody know?

 

Yep, the only difference between them is the injectors. A 4.3 throttle body is also the same size. The only thing I would do after thoroughly cleaning the JY throttle body is the ultimate upgrades. (grind the ridges, injector pod spacer and adjustable fuel pressure regulator and if it fits a throttle body spacer.) If your current 305 throttle body pressure regulator is ok, and you don't want to go with an AFPR, use the injector pod off your existing throttle body and your fuel pressure will stay the same as it is now. I would also have the injectors cleaned and flowed while I was at it. witchhunter.com does a great job at a more than reasonable cost.

 

Awesome! Off to the junkyard I go.
Thanks alot for the quick response!
