hey... anyone know what i can use to bore out the exhaust manifold... I already passed a Metal Brush using a Power Drill. Cleaned that carbon up just nice. Anyone know or have a pic of what i need to bore it out. thanx man
 
Dremel or rotorzip

If you have a dremel you can use that but takes some time or a RotoZip would be ideal. Anything you can hook a cutting stone to.
 
I made a fixture that clamps to my mill table.And the header bolt
to the fixture.Then I can then bore the collector out with a bore-head
in the mill.It takes about 30 minutes to set up,& about 10 minutes to
bore each collector.

I use the same type fixture to bore,& then port my plenums.

Do you think I could port mine with a drill press?

If anyone has done this let me know casue I deffantely don't have the money for Headers
 
Air die grinder and a couple cheapo carbid bits will do the trick in about 20 minutes per collecter. I was using stones with a drill for a while, that was a waste of time and lots of it.
A flap sanding wheel to finish the job is nice too. But a die grinder and compressor is a must for many projects on this car.

good luck
