Question about LT1.....?

I have a 383 (see signature). I just purchased a complete LT1 intake on Ebay( $125.00) to replace my TPI. My question is this .... will the stock injectors and throttle body feed enough air and fuel for my set up? I have a mild cam (duration 220/224 .502/ .525 lift @.050) Or Will I need to upgrade to bigger injectors and throttle body?

The stock throttle bodies are the least of your concern.

I would get 24# Ford Motorsport injectors (matched) and be done with it.

You will need a tune...

I agree with Bogus. You can go to a 52mm TB later. If you ever plan on going bigger, go ahead and have the intake bored for the 58s.

Your signature shows 24lb accels. If the only thing you are changing is the intake, you may be ok, unless you plan to see more rpms. Personally I would contact Alvin and ask him.
