I am not to sure but I found some bigger injectors on ebay for my car. Its a 305 TBI. They have the regular 350 injectors with o-rings and gaskets, everything is brand new, for 150 bucks and then they have the caprice 350 injectors which were even bigger I think for 165.00 brand new with o-rings and gaskets. First off, is this a good deal? And secondly, with my mods (cam,intake manifold, full exhaust, lots of bolt ons, check the site for more) do u think I need bigger injectors? I am running at 12-13 psi as we speak but I notice on the guage it kinda flutters back and forth and it seems like the outside of my throttle bores and around my injector spacer (just a bunch of gaskets pilled up) there is like fuel stains and sometimes I can even see the injector spacers covered in fuel after the car has run. Is this normal? Thanks. Oh and later on I do plan on spraying the car with a 75 shot and working my way up to 100. Thanks.

Heres the injectors
