545 -----575hp

585 hp with a reasonable correction factor i.e. real atmospheric data input not hurricane eye barometric pressure.

With AFR heads and 9.6:1 I would predict 620 hp.

570hp at 5400rpms.

We just dynoed two 516 EFI'S (hp500 EFI ) with 741 cams Merlin 320 heads 9.3 compression . One made 570hp the other made 582hp both at 5500rpm.

What dyno equipment is the motor tested on? Tested to what standard?

Very realistic numbers. Now if you had stated 620HP or something, well that just puts a whole new paint job on things. What torque/rpm numbers did those motors produce?
