If anyone else is interested in getting a 4200 turbo manifold

Now is the time to express your interest, consider $1150 as a rough price this will be lower as the qty. increases to spread the set up charges over a bigger number of parts.

The manifold top mounts the turbo (Garrett GT40 flange)and bottom mounts a Tial 48mm wastegate.

If your running a '57 or earlier then their is plenty of hood room for the turbo.

Steed Speed http://www.steedspeed.com is making the manifold (no you won't find the manifold on his web page) but you can see others that he has done .

Thanks

Marc
