dyno day for the demon

Thats a very mild 416...
Yes, the shop that put together my internal parts asked me if I was building a race car and I told them no. It also has edelbrock heads and dougs headers icon forged pistons, lunati 60404 advertised duration 279in 287ex. also has roller rockers. Holley 750. Edelbrock performer rpm intake. I actually thought it would be doing a little more. Sure does feel like it when I stomp on that pedal.
