Im gettin a 89 5.0 gt soon in the future and was wantin to get on top of things before hand. The list of things im gonna/hoping to get are:
-borla catback
-BBk CAI
-BBK equal length headers
-Throttle body
-Underdrive pulleys
-Performance intake manifold kit
-stiffer subframe connectors to keep it stiff.

Anything im missing or things i need to add to keep it equal or w/e, do i need a new carb because im chockin the bastard or what. anything yall have is great. Thanks

You're EFI, no carb. Also, I would skip the UDPs. What are your goals for the car? Do you plan on racing it or is it just gonna be a fun little daily driver? What you plan to do with the car dictates what kind of modding you should do.

here is the order you should follow, exhaust, gears, h/c/i

yea but ive heard with this car the cam is perfectly fine the way it is. so im not gonna bother with that. And yea its gonna be a daily driver but a drag machine on weekends. And might be stupid might be not, but can you change the gears on a auto?? cause if you can i want the 3.73 i know the 4.10s are best for acceleration and performance wise but idk if she would be ready for those yet.

gears have nothing to do with your tranny.. they go in the rear end.

also, the stock cam is crap.. and even if you DONT have a stock cam, you dont know what it is.. therefor, no matter who tells you its good... it needs to go

mjr46

dang...who you been smokin weed with??? now if it were just gonna be a D/D then I'd say stock cam will be okay for a while but since you have plans to race it, if you ever have any hopes of making it fast without a power adder then you need an H/C/I for sure = heads, cam!! and intake

gears have something to do with your tranny cause you need speedo gears in the tranny to match with the gear ratio in the rear you want the 4.10's in that auto i agree crappy cam get a different one

AmericanMuscle23

haha well im deff choosin you guys who have the car then the site who's tellin about it. Thanks, yea i heard if ur gonna get a cam you need intake full exhaust and heads before you do it. But in all honesty i really dont know what a cam does besides make it extremely loud, and where would i find one ive searched but its still eluded me. thanks for the help guys

gears have NOTHING do to with the tranny... what so ever!!

the only reason you have to change the gear for the speedo is because you effectively change the final drive of the vehicle which is matched by the speedo gears in the tranny. (which have nothing to do with ANYTHING aside from making your speedo accurate)

so if you run 3.73 gears, with 3.08 cal speedo gears... your speedo is obviously going to be off.

again. rear end gears have NOTHING to do with the transmission

You really need to sit down and do some research first. A cam has nothing to do with how loud the car will be. If i were you i wouldnt even attemp any modifications till you have a understanding of things. Theres alot of good info on this site, all you gotta do is take the time to do some research. Trust me its worth it.
