ok I am just trying to get more out of my stock 5.0 without breaking the bank. Ihavegt-40 heads, cobra inake (upper and lower) roller rockers(1.6's) and a e-303 cam, just wondering if i can get by with all that, without changing inj, T/B and MAF. let me know what yall think!

(trying to pull 13's out of it, ran a 14.5 stock)

you need to go on ahead and upgrade. I've herd ppl running lean with stock injectors and that setup. as for the t/b and mass air, you need some air to go with that fuel.

You can them them fairly cheap on eaby

despite what motorman has said you dont "NEED" to change your injectors. Your are infact in the ballpark hp range for changing them, however your still a decent amount off. I would save the money for other areas of the car. I would indeed upgrade the tb over the stock and the maf but if you do that you might as well do the injectors. If you dont have the money to do it now, or to do it all at once go ahead and just wait. Because if you change the maf, you should get it calibrated for 24lbers for future mods. As for the tb i would change that whenever you have the money for the slightly increased throttle response expecially if its an automatic, but judging by the times it is not .

the stock setup is good for 300 whp. you dont need to change. put your money into a dyno tune.

+1 however you are close to that mark my good friend, by the way tooslow5.0, i love primer and i love your sig, please dont paint it

your current set up should be fine..just go get a dyno tune that'll tell you the a/f through the entire rpm band

instead of the dyno tune, get a tweecer or mega squirt if you've got the knowledge. I always say, if you want something done right you gotta do it yourself.
