Contemporary 428 headers? Other questions, HELP!

I just purchased a 1992 Contemporary Cobra with a 350 chevy motor. I have a 428 and Tremec trans that I want to install but I need some help.

1. Who makes under car headers (as opposed to side exhaust headers) for my 428 that will fit the Contemporary Cobra?

2. Can I buy motor mounts for the 428 (vs. existing 350 chevy) motor that I could then have welded on to the frame or am I going to have to get them fabricated?

3. Similarly the existing radiator looks old and marginal. Any sources you can think of for a bolt in, quality aluminum replacement?

4. The pedal arrangement is tight, in fact real tight with my left leg feeling like it comes up to my chest everytime I shift this monster. I'm assuming that, given the existing size of the leg enclosure area coupled with the pedals being offset to the left that I can't do much here. True?

Many thanks for your thoughts and help here.

Try Cobra Restorers for headers, otherwise there is a place called "Tubular Automotive" on the east coast that did Contemporary headers. I don"t know how others feel, but I hate my TKO II tremec. First gear is all but useless and seldom do I use o/d. I would opt for something with a first gear in the 2.60 range (T-10 Richmond). With your 428 you would find the 3.27 first gear nothing more than a "stump puller". This is just my opinion however, so good luck. Mike Beamish

Tim, regarding the pedal placement, not much you can do about the offset and tight spacing but one thing I did that helped was remove the seat rails. This lowers the seat by a little over an inch and I moved it back as well. This straightened out the angle (on my leg) somewhat and was an improvement.

Check out the new TKO 600. First gear is a MUCH better 2.87, has a choice of O/D ratios, multiple shifter locations and is rated at 600 ft/lbs. I think there will be a glut of used TKO II's on the market soon.
