Guess the HP!

My 440 is about to hit the Dyno

Looks like it’s already on the dyno.

Whatever the numbers are on the dyno sheet, just understand that testing that same combo on a different dyno could yield numbers that are +/-50hp.

The few times I’ve tested a BBM with fender well headers(What they appear to be in the pic), the top end of the curve fell off earlier than what was expected based on the rest of the combo.

On the dyno here, I’d be looking for something in the 575hp range.
Could easily be over 600 with normal 2 x 3.5 headers, and more cam duration.
