You have to remember that this is; 1) Not a Corvette 2) that it is an automatic Camaro 3) the dyno is just a tool.
The ZO6 427 is rated at 505hp and 470tq This engine on an engine dyno which is used for NASCAR spec engines and with normal timing made over 550hp and 565tq.
We tuned this engine on a Mustang Dyno which we have found reads approx 5-7% lower than when we use the Dyno-Jet.
Yes, we used forged internals.
