Replace cracked manifold with Pacesetter header? #1104522

My ’87 2.6l has a badly cracked exhaust manifold. I'm looking for a replacement, and several people are helping, but so far no luck. I'm going to try a little longer, but just in case I can't find one I’m starting to investigate my alternatives. One of those alternatives is installing a Pacesetter header.

I'd really like to hear from anyone who's installed a Pacesetter on their Gen1!


I’ve searched what little info there is here, and the consensus seems to be that it won’t improve performance at all — I’m okay with that. I'm not looking for a performance boost, I'm looking to seal off exhaust leaks.

My biggest question is just about getting it to fit; from what I can see, it won’t bolt up to the existing exhaust. Some fabrication would appear to be required, but I’m unsure just how much.

Also, having just finished a Weber carb installation, I'm wondering about the need to re-jet the carb. Since the stock manifold, from what I've read, breathes at least as well as the aftermarket header I'm hoping that re-jetting won't be necessary. Am I off base?

Have you exhausted efforts finding a manifold at wrecking yards? Searched car-parts.com ? These trucks are getting harder and harder to support with parts because of their age I think. Many have gone to the crusher.

Yes, I have a constant search set up for the wrecking yards. You're right, they're getting harder and harder to find.
