Our LT1 Stock Engines in our Impalas and Camaros it popular to add a 1.6 RT or RR's replacing stock rockers measured at 1.47.
Dyno testing with Bryan Herter showed measured 15hp rear wheel improvement. Got another 5-7 with an upgraded tune for total of 22hp.

Stock Eliminator, in theory, is the antithesis of the internet. People have worked for 30, 40 or more years to find out what they know about what makes their combo get to the end of the track before you. Now, you want them to tell you what they learned?
The internet can seem to be about "tell me what you have worked hard to learn. Oh, and, thanks." But responses can be cryptic. And I would expect them to be. Just like in the "prehistoric" days. You have to take what you're told and make the best of it.
