LT1 cam is roller; he has a Cross-Fire motor which is flat tappet. Decent choice as far as specs, except it won't work in his motor.

http://www.compcams.com/catalog/082_083.html Look at the 12-388-4, 252AH-12, about halfway down the page.

I don't know about "red dot", but I know mine are black.

It means that you've posted in that thread.

Red? huh. What OS system, ISP and browser do you use?

Those specs look good. I think you can ba a llttle more aggressive with the duration. I would get a custom grind.

212/212 or 212,214 with a LSA of 114. 112 is too much for an automatic if you are conserned about smoothness and maintaining engine vaccum at idle.
