Guess the HP

It was 20 years ago.
Cam was 270’s @.050, .660 lift.

My notes say the FW headers were 2 x 3.5.

I’d say the length was the big player there.

The FW headers were what was used in the car.

This was a job where the motor was updated from a 446 to a 493.
I basically just replaced the rotating assy and used a different cam.
The 446 combo had a Comp 306R-8, .625” lift.
It was a combo he bought from MM.

With the FW headers it made:
513tq@4100
532tq@4800

551hp@6500
548hp@6800

In the car, with the extra cubes it went almost 1 second quicker in the 1/4.
No changes were made to the car.
