I have a bad injector in my 89 GT. My buddy gave me 2 complete sets of injectors. One is set of used , but good, 19lb. stock injectors (F2TE-A3A) and the second is a NEW set of 24lb. injectors (F1TE-D5A). I would really like to use the new set. The engine has a E303 cam, GTP 40 heads and a stock intake. Would the 24lb. be to much? Thanks.
