Guess the HP!

The motor is going in a 72 Duster with mini tubs and Caltracs... Street/strip car.

I'm hoping for 10.90s on motor but I might be overly optimistic. I'm running TTI 2 inch headers on the car. I didn't have them on hand at the time we bolted the motor to the dyno.

The first was today but isn't very promising..... pulled 487hp, it was done making power at 5300 rpm so something needs looked at.

Yeah, don't get to down on it. My 1st pull with my new 470 showed 601 but 684 ended up being the most common number, I'm sure there's plenty left in it. Like PRH said post the sheets.
There's lots of smart people that can help
