W2 408 Dyno results today !

Frankly, I would have thought 500/500 would be a slam dunk for that combo, with probably another 20 or so on the table with more cam duration.

The heads on the motor for the sheet I posted flowed about 280.

I agree ... but 493/483 is pretty close to 500/500 . But I did expect it to continue pulling past 6500.
