witch one is better

holley. its bigger. yours if you still have an lo3.

Well i have a 355 with the stock lo3 305 throttle body.

then either the turbo city tbi or the holley will work. actually your stock one will work but if you are making over 360hp, it could be a restriction. i would get the holley, just so if you do go bigger, you have the room. holley is 2" turbo city is a bit smaller.

I would get the holley because it is new and not remanufactured, comes with injectors and regulator and larger bores. I called about the turbo city TBI and the bores aren't quite 2". I have also heard that someone had a TBI unit from them that was slightly warped and created a vacuum leak.

Hey thanks for the help guys just one more question. Does the holly have and (afpr) with it or do you have to buy one sepearte. And thanks again for the help

I am not certain but i think that it does. I think it is the kind that has a little torx bit that you adjust without having to take the injector pod off everytime.

It does. A 4 mm allen stock is all that is needed.
