For a 5.0? Besides the factory headers?

Big hint: It's not the headers that are the bottle neck, but the front cats from the factory ...

Hello

I have Fox Manifolds on my 351w. Bigger exit hole. about 1/4"

BUT you must do some sort of steering mod!

Im dropping a carbed 302 into one of my tbird shells the exhaust has already been chopped off but i dont have any extra factory tbird 302 manifolds laying around so i was looking into headers and SCP was all that i could find as a bolt on

summit has tons of shorty headers but i was unsure if they were a true fit

Well, if all you NEED are factory 5.0HO headers - there's a couple of 5.0 MN12s in the local yards.

Past that - SCP is all that would fit out of the box. Others will usually take mods to the steering rod or something else.

The MAC shorty headers that are a direct replacement are MAC # 903091.

You might be able to find stores with new old stock or left over stock.
