will the 94 Edelbrock header fit a 97?

If not is it beacuse they are the same as the Mac headers?

 

I purchased my 94 model Edelbrock headers from a guy that had them on his 97. They work just fine, but you will need a s-shaped piece of pipe made to hok them to your catback system. No big deal though. Lots of guys with the 97's change over to the 94 style single cat headers.

 

Was he using a single cat Y-pipe or his stock dual cat one?

 

it'll fit...

(diff emisions hookup is the only diff i believe)

 

You have to use the single cat y-pipe that comes with the headers. Your factory y-pipe will not work with them.

 

the emission threads are unique to itself on 97's,,u have to get an adapter...mine came with my jet hots, before that i tried to put 94-95 headers on my 97, and the threading wasn't compatable.
