With the popularity of Ford and Chevy engines nearly every aftermarket big block part bolts to them. I just e-mailed Edelbrock and Hooker (Holley) and asked if they had and intake manifolds or exhaust headers that will fit a '73 Buick Riviera 455 V8 and of course I got a no.

So now I'm wondering if there are any out there. I'm nearly done blowing primer on my car and I was wanting to begin putting new belts and hose on and work that old exhaust of of there.

Yes there are, TA Performance (http://www.taperformance.com) has them as well as Poston (http://www.postonbuick.com) Those two alone should get ya started. smile.gif

They come up regularily on ebay too.

Ebay is a great source, but sometimes you have to be patient for things to pop up.
Also, swap meets are great places to find buick stuff....has been for me, anyway.
