Can I use stock injectors with this?

i have an 85 ta lb9
i'm guessing stock injectors are 19lbs?

can i use them with the following

shorty headers
aluminum l98 heads
lt1 intake
bigger cam? (haven't decided on which cam to go with yet. if you have a suggestion, chime in. emissions is no concern. car will only see limited street use. MPG isn't a real issue either)

Do a search on webcrawer.com or Yahoo for "Injector Calculator" and you should be able to find an online version of the software needed. You plug in a few guestimate values (projected HP ratings) and you can find the injectors you need, or supply the fuel pressure and injector size, mutiplied by the number of cylinders and you'll get the max projected HP potential with that combination.

From what you've posted, your 19's should be fine for the HP you'll get with those mods. At the most you can do a fuel pressure bump and meet the needs if you get wild...

Exactly, you'll be fine. As for the cam, I'd go bigger. I'd stay away from a cam w/ more than 550 lift. I don't think the heads will flow in stock form. However, with some porting, I'm sure those heads will make very respectable power.

use those injectors and invest in an Adjustable Fuel Pressure Regulator and you'll be fine.
