1990 Gt 5.0 5spd Want MORE POWER!

long tubes are overkill(too much airflow not enough backpressure) until you get h/c/i thats when long tubes make good power and a gt40 intake is probably one of the best performing street intakes out there but expect to pay, also i agree with PoopDawg that if you top out in fourth gear @ 125 then you have gears cuz i know in my car (see sig) that i hit about 105 to 110 at the top of third.

trick flow heads, cam, intake

or do suspension stuff like upper and lower control arms and some sticky tires

When i trapped 100MPH i was at about 5400RPM in 3rd gear.....and i wont go any higher than that......So what gears do u think i have in it?
