Beemon Posted May 18, 2017 Share Posted May 18, 2017 Any 364/401/425 exhaust manifold should bolt up to your block, fitment to your system may be a bit difficult as I think the manifolds changed quite a bit year to year. For your manifolds, it looks like 57 and 58 interchanges according to Russ's website. Link to comment Share on other sites More sharing options...

I have those. Please pm if still needed. Best Regards, Greg PS Right side or left(driver), side? Single or dual different if driver side, common if passenger side.
