I am planning on swapping in a 350 in place of my 305 but i dont know if i need a new throttle body or not. Can i use my old one or would i have to get one off a truck in a junkyard? What other parts wouldnt work off the 305?

Any advice would be greatly apreciated

yes they are pretty much the same. the wires may be a little diffrent though

 

You can run your normall throttle body its just not recomended .You can run the 350 with your stock 305 setup it just wont perform well . To get maximum performence you want a 350 chip,670 throttle body w/ 350 injectors,a 350 knock sensor,and a 350 esc module.I ran the stock 305 stuff on my car for like 5 months and I was running high 15's until I swapped to the 350 parts and now i run 14's all day.Good luck

 

The throttle body itself is technically the same. The injectors are different though. He doesn't have to worry about any of the wires...its gonna be in the same car. Everything will hook up the same. If you run your stock TB get a set of police car injectors...(65lbs??). And your gonna need an adjustable fuel pressure regulator. You are definetly gonna need a chip burned also or you'll never run right.
