I have a few questions. First, I will be installing kooks long tubes on a '94 Trans Am GT and I wanted to know if anyone has had clearance problems. Second, what is the difference between long tube and shorty headers?

 

I dont think that u will have any clearance issues with the kooks headers. They are supposed to be some of the best headers that u can get for the lt1. I have heard alot of people use them without any complaint. Long tube headers are headers that extend past where the stock manifolds stop, usually partially under the car. Short tubes stop just about where your stock manifolds end. You might run into clearance issues with bottoming out a set of longtubes if your car is lowered.

 

I installed these on my old car (97 Z) and they were a cake walk. There was no clearance problems with any part of the header. I also didn't need to remove the starter, alternator, or jack up the motor.

 

i may have heard some ppl have problems with starter clearance on the kooks stepped headers (1 3/4 - 1 7/8 primarie) but im not sure what was done about that

other than taht i dont think u will have a problem

 

Kooks stepped 1 3/4-1 7/8 here...No clearance issues with starter either the stock or LT4 will fit (or any other with similar dimensions...Had to go to an AC PF454 oil filter which I believe is the stock size filter which leaves 1/4-1/2" of clearance and makes it easy to take it off to change the filter...The only clearancing issue was grinding a hair off the steering shaft bolt head where it barely contacted a header tube...May not be an issue for the 1 3/4 non-stepped though...Very nice header with great plug access, fit/finish, ground clearance, etc...highly recommend...

is there an issue with the headers and CANTON oil pans?

 

I have heard good things about Kooks and clearance. Making sure you have motor mounts that are in good shape would also be cheap insurance that you don't run into clearance issues after they are installed.

 

when did pontiac decide to make a trans am gt?

it ididnt last long , it was just a name
