Hi All,
Looking at a black 98 trans am.
Can someone tell me the primary difference between the 98's and 1999+.

Thanks,
Steve

 

It's just detail stuff, they all use LS1s from 98 and up. The bodies even look the same.

 

The '98 LS1's also had a beefier fuel system.

 

beefier? What do you mean?

 

The 10th digit in the VIN is different.

 

better fuel system???? not exactly.... what the 98s have that the 99s don't as far as the fuel system go are around 28# injectors and a metal gas tank (meaning you can run a racetronics plug and play fuel pump) , while the 99s have around 26 # injectors and plastic fuel tanks. other differences are that on 98s not all of the gaskets on the front of the gaskets are reusable, but you can put the 99+ gaskets on there... and some of the 98s have borg warner trannies instead of tremec like the 99+...

oh yeah and the 99s are newer

 

Borg Warner? Well it's still a T56 right? Tremec bought Borg Warner's manual trans division.

 

yeah its still a T56...

 

The 98s' had a single outlet exhaust. '99 and up had dual pipes.

 

they made a single outlet exhaust when the bumper has a molded spot for 2?

 

Was there any difference in the power output and or body style is what I was after...

How about the interior..

 

www.camaroz28.com, mostly fourth genners over there, check it out.

 

Strange as it may seem the rear bumber was molded for 2 outlets, but only one pipe emitted from the rear of '98s. Check out some pics you'll know what I mean. Power for '98 and '99 was the same. Trans Ams' were rated at 305hp, those with WS6 checked in at 320hp.
