Hey i was wondering about what kind of injectors should i go to. How big can i go with a 305 tbi. Want to make my 305 a lil faster till i get my 350 completely rebuilt and ready to go. Thanks for any input.

 

If you have a stock engine then just keep the stock injectors (45#), you wont need anything bigger . First performance mods should be open element air cleaner, headers, hi flow cat, and 3" cat back. That should give you some really good gains and will be compatible with the 350.

 

Hey thanks but i already have a new exhaust system and a gutted cat and put on a bigger pipe going back to the exhaust. Also, i have super comp long tube headers on order that i plan to put on. And i putting an open element air filter today so i can start getting some real use out of my 5" cowl induction hood. So would it be time to put on big injectors and i heard that u could put a spacer on the throttle bodies. Will that really improve ne thing? Thanks.

 

go to the tech articles and do the Ultimate TBI mods, there is a way you can make your fuel pressure regulator adjustable, all you need is an increase in fuel pressure and not bigger injectors. Next, i say you add some gears and a posi.
