Had some requests for pictures of how Dynatech LS headers fit in First gen camaros. They are 3/8 flanges, 4 bolt donut style collector, tig welded and 1 7/8 primaries with 3 inch collectors.
They DO require msd wires or similar, as two cylinders must be rerouted...... but they fit nice and have a ton of ground clearance. Nice thick tubes, high quality material. Very nice polished ceramic coating, done by Nitroplate, not like some of the other brands flat, coarse ceramic..... great value for the price.
I don't work for dynatech or anything, just had some requests to show some pics.....
Also note, this is installed with ATS motor plates.
Those are Speedtech control arms in the pictures, on a stock subframe. These headers also clear speedtech subframes with a rear steer rack. I am not sure about stock subframes with a flaming river rack conversion, but there is a ton of room down there so I am sure they will fit.
I also know these headers work Awesome for a tri five chevy ls1 conversion, and also clear a jim meyer tubular control arm and rack conversion for a tri five.
