Vortech kits have been made for decades that are designed for 19 lb injectors.
You need a T-rex external pump and an FMU, both of which come in vortech's kit.
+1, the ad on my jegs book does not have a star by the order number stating it needs bigger injectors. Also I've seen ever so slightly modifed stangs with just a cam, chip re-program, and bbk shorties make 415hp on stock injectors.
8psi is make for your car, you have the compression for it, plus your stock pump flows more than 45-55psi right? So run to autozone, snag a good timing light(Keep your receipt), come home and install the damn S/C, use your timing light and time your car perfect(Perferablly on 89 oct) or 87 with octane booster(SThe silver can from autozone) test it out, do your final timing, return your timing light and get your 80 bucks back, get a short throw shifter and let's starts ****ing around with some Zo6's and maybe a C6. I aint no punk bitch LOL
