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? :shruggy:

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!
