Is there anything such as a performance tbi injector. Or do they all preform the same way. I know they make differant injectores for differant engines. I have a stock 305 TBI, should I use a differant engine injector, or do they have a "bigger" one for the 305's.

 

you will probably run way to rich with 350 injectors. do the free AFPR Here and then use a scan tool to get it as good as you can.

but with no mods, i don't think that this kind of stuff is a good place to be looking... i would read the tech articles for utlimate TBI do that, and and open element, and exaust. first, then work on gears/posi.

 

I should do the ultimate TBI mod, I have k&N custom open air element. I allready have a 1993 Z28 rear end with posi and 3.23 installed in my RS.

So it looks like the ultimate tbi mod, and exaust for me.
