The everyman's 360 LA Eddy headed engine dyno tested

13.2s are a PW of .080 at a race weight of 3300 that is 3300x .080=264 hp required. if you lost a half second due to chassis set-up, it would be .089, and .089x3300 =294 hp
Just saying
It's a street car not set up for drag racing, and it runs exactly what I would expect it to.
