Grand National/NASCAR Cams

[Brutalowner]

Does anyone know the actual camshaft specs for the RB Wedge engines run in the GN/NASCAR super speedway days?
Flat tappet/roller, Duration @.050" LSA, etc? What was their working ranges on-track? 4500 coming out of the middle, to 7000 at the end of the straight?

Might be a question to ask on the aero forum.  This would be the logical place to post it but in this particular case you might get better results there?

According to the Chrysler Performance Bulletin ( not for sure on the part number of the book), the short tracks used a cam labeled stx-22 Racer Brown with .020" intake valve lash  .024" exhaust.   The larger tracks used STX-24 Racer Brown with .028 intake  .032 exhaust.  There is also another cam used for all tracks from Chrysler 436  pn- 3614458 with .024" intake .028" exhaust.

This comes from the book from Larry Shepard you could get through Direct Connection.

Thanks for the input! I found the specs for the Racer Brown cams, but haven't been able to dig up the specs on the DC cam. I got the info I was looking for, Thanks Again!
