Headers or manifolds for turbo??
I'm building a turbo 4.3 for an '83 cheVette Pro-Touring project (see the Welcome to the message board section for photos). Exhaust on the 4.3's is a big issue when swapping in a Chevette. I have the factory manifolds that I can simply swap sides to point forward, but considered modifying some ebay S10 headers instead. A local custom exhaust guy said on turbo cars, inlet exhaust flow isn't nearly as critical as outlet flow. He said a turbo converted muscle car he worked on made more power when the guy took off the headers and put factory manifolds back on. Any thoughts?? Thanks for any input.

You might check to see if the factory Syclone/Typhoon 4.3 manifolds will fit. They are pretty compact and I know of two or three trucks that have went LOW tens with them.
