In light of what you did with yours, I took a similar approach but used 13.8 compression with a 390 and LS7 top end that I reworked. Cam is a 255/263 107+2. It actually drives better than one would expect..... You were the only person I could find that had anything close to this size cam in a street car with some type of results or I may have not even attempted to test it. The link is an idle clip. Figured since the thread made me fall in the rabbit hole, I'd revive it and give it a bump.... Wish me luck!

OP outstanding results thank you for sharing all the info you gathered in the process is really helpful data for the hands on forum class.
I too build a 440 ci lsx block ls7 and went 10.60 on my first track outing so no biggie on my second went 10.36 others doing better been working on it and perfecting their craft it takes time and dedication at the end of the day regardless of others you have a killer stock block heads and cam build and a real nice car you build and enjoy all day every day.
The crowd quoting other people’s car got ? What ?
My last track day Feb 3 heads and cam llsr ls3
